3966 Best Sights in USA

This one-of-a-kind education center focuses on a sprawling 1½-acre model of the entire San Francisco Bay and Sacramento–San Joaquin River delta system, complete with flowing water. Now open for public exploration, the model has been used by the U.S. Army Corps of Engineers to reproduce the rise and fall of tides, the flow of currents, and the other physical forces at work on the bay.

The 30-minute tours at the famous brand's factory are unabashedly corny and only skim the surface of the behind-the-scenes goings-on, but this flaw is almost forgiven when the samples are dished out. To see the machines at work, visit on a weekday but call ahead to confirm if they will indeed be in operation.

California's oldest state park is the best place to see old-growth redwoods without going north of San Francisco, and it's far less crowded than Muir Woods. The parkland ranges from sea level up to 2,000 feet in elevation, which means the landscape changes often, from dark redwood groves to oak pastures that are deep green in winter and bleached nearly white in summer. The countless waterfalls are the most visible during the winter and spring rains. To get a feel for the redwoods, take the Redwood Loop Trail, an easy half-mile path, great for kids, that takes in some of the tallest trees here, including the Mother of the Forest and the Father of the Forest. Pick up the trail from the parking lot across from the visitor center, inland at park headquarters in Boulder Creek. A brochure you can pick up here points out significant trees along the way.

If you have a little more time, consider taking the Sequoia and Skyline to the Sea trails for a 4-mile loop that takes you past a pioneer family cabin to a platform overlooking Sempervirens Falls, up the slope of Slippery Rock, and then along stretches of Opal Creek (where you meet up with Skyline to the Sea).

Hikers looking for a challenge might consider the strenuous but scenic 9.5-mile trek from Rancho del Oso valley (accessed on the western portion of the park, east of Highway 1) uphill to Chalk Mountain, which meanders along a ridge with sweeping views of the park and coast before steeply descending by way of the Whitehouse Ridge Trail. Look for the Clark Connection, up Canyon Road, as your starting point.

A short walk from the highway on the Marsh Trail leads to the Rancho Del Oso Nature Center (www.ranchodeloso.org). Open on weekends from noon to 4, the center has natural-history exhibits and is the starting point for several self-guided nature walks.

This 12-acre beach park is popular with local families who enjoy the lovely Brazilian-walnut hardwood boardwalk, plethora of parking spots, and sail-shade canopy-covered walkways and benches. Kids will get a kick out of the playground and adorable large sea turtle sculpture (grown-ups will appreciate that it was made of repossessed metal from an oil rig by a local artist). Free beach wheelchairs are available, as are umbrellas and lounge chair rentals for a small fee, and a concession dishes up sandwiches, salads, and snacks like ice cream. Divers love the four sunken ships off the coast as part of Florida's artificial reefs program. Amenities: lifeguards; food and drink; parking (fee); showers; toilets. Best for: snorkeling; sunrise; sunset; swimming.

White sand beaches, blue-green waters, and a tall lighthouse mark this quiet beach at the southern tip of Cape Lookout National Seashore. A boat is the only way to get here. Passenger ferries leave from Harkers Island and Beaufort, while passenger and vehicle ferries leave from Davis and Atlantic. Land on the sound side, then walk across a path to the beach, where you'll be greeted by a long beach strand full of seashells, including large whelk shells. In season, you can also climb the lighthouse tower or tour a museum in the keeper's quarters. Amenities: toilets. Best for: solitude; sunrise; sunset; swimming; walking.

Moss Beach's biggest attraction is the spectacular Fitzgerald Marine Reserve, a 3-mile stretch of bluffs and tide pools that occupy 32 acres. Since the reserve was protected in 1969, scientists have discovered many new aquatic species. The best time to visit is during a zero or negative low tide, when you're likely to find crabs, anemones, urchins, and sea stars. Volunteer naturalists are around to answer questions on the weekends. Self-guided tours available, but pets are not allowed.

Lion and tiger habitats, the Giraffe Savannah, and a 4-acre mixed-species area called the Serengeti Crossing that showcases zebras, ostriches, warthogs, and wildebeests keep this zoo roaring. The Tropical Forest, with its Western Lowland Gorilla environment, is a big draw, and kookaburras, emus, and kangaroos populate the Outback Trail. From May to September butterflies flit and flutter at Butterfly Landing, where docents are on hand to answer questions and give advice on attracting the colorful insects to your own garden. Franklin Farm entices children with sheep, goats, and other farm animals. In winter, call in advance to find out which animals are braving the cold. The park, 4 miles from downtown, is reached by Bus 16 from the Forest Hills (Orange Line) or Andrew (Red Line) T stops; there's plenty of parking.

This old family-friendly standby, with six locations including Bangor, is famed for its peanut-butter whoopie pies as well as the classic black-and-white, and can grant any special flavor combinations by request with 24-hour notice.

The town comes to life—and traffic to a standstill—on the third weekend in October, when some 250,000 people gather for the Half Moon Bay Art and Pumpkin Festival. Highlights include a parade, pie-eating contests, live music, plenty of pumpkin-themed food and drink, and a "weigh-off" of giant pumpkins, some more than 1,900 pounds.

This 4-mile stretch of sand is perfect for long walks, kite flying, and picnic lunches, though the frigid water and strong rip currents make swimming inadvisable. There are three access points (Francis, Venice, Dunes) and four beaches (Francis, Venice, Dunes, Roosevelt). One access point (Francis) is in Half Moon Bay; the others are north of town off the highway. To find them, look for road signs that have a picture of footsteps. There's a visitor center and BBQ pits at Francis and picnic areas at Francis and Roosevelt. Dogs are prohibited. Amenities: parking (fee); showers; toilets. Best for: camping; solitude; sunset; surfing; walking.

Stop for a spell at Harley Farms, a restored 1910 farm and fully operational dairy that stretches over 28 acres and houses 165 goats on 9 acres of pasture. Two-hour weekend tours follow the milk trail as it moves from goat to dairy, then from curd to cheese (Harley's is renowned for its chèvre, fromage blanc, ricotta, and feta). You can walk around the yard, spy on goats and llamas, and read detailed signage describing the buildings and operations. The Harley Farms Shop sells cheese, lotions, soaps, and gift items. Monthly dinners, conducted in the old hayloft showcase local, in-season produce and book up fast.

An outcropping of nature in a sea of North Berkeley homes, this is an unbeatable spot for a sunset picnic. Look for amateur rock climbers, after-work walkers, and cuddling couples, all watching the sun sinking beneath the Golden Gate Bridge. Come early to grab a spot.

Straight out of a Looney Tunes cartoon, this activity-focused playground with oversize replicas of familiar objects offers lessons along with some fun. The whole family can gain tidbits of knowledge on earthquakes, animals, and insects. Explore gravity in the Physics Forest, which features 12 interactive experiences. In the sunny atrium, kids assume the role of ants on their daring ascent. Outside they can run and climb along a running river or take on a tricycle race. The museum is practically designed to wear out the little ones and give parents a much-needed break.

The featured attraction here is the 355-foot-long Knights Ferry covered bridge. The beautiful and haunting structure, built in 1863, crosses the Stanislaus River near the ruins of an old gristmill. The park has camping, picnic, and barbecue areas along the riverbanks, as well as campgrounds accessible only by boat. You can hike, fish, canoe, and raft on miles of rapids.

Runners, joggers, and power walkers charge along the 3.4-mile path that encircles this 155-acre heart-shaped natural saltwater lake. Crew teams glide across the water and boatmen guide snuggling couples in authentic Venetian gondolas (fares start at $60 per couple for 30 mins; 510/663–6603, gondolaservizio.com), while yogis, jugglers, and picnickers look on from the shore. Lakeside Park, which surrounds the north side of Lake Merritt, has several outdoor attractions, including the small children's park, Children's Fairyland (699 Bellevue Ave.), and the Lake Merritt Wildlife Sanctuary, a water and air fowl haven that was also North America's first wildlife refuge. Don't miss the nearby Grand Lake neighborhood, centering on the parallel strips of Lakeshore Avenue and Grand Avenue, for good browsing and even better eating.

If you're curious about the rehabilitation of marine mammals from the Pacific—and the human practices that endanger them—stop by this research hospital and rehabilitation center for rescued aquatic creatures. An observation area overlooks pools where sea lions and seals convalesce, and informational exhibits explain the center's history and work. You'll learn even more—and get closer to the animals—on a 45-minute docent-led tour.

The world's first oceanarium was constructed in 1938, 18 miles south of St. Augustine. This National Register of Historic Places designee, now part of the Georgia Aquarium, has come a long way from marine film studio to theme park to its current iteration as dolphin research, education, and entertainment center. The formal dolphin shows are history, but you can have a far more memorable experience with interactive programs that allow you to swim with and feed the animals or become a dolphin trainer for a day. Programs start from a simple "touch-and-feed" option and are as elaborate as a super-expensive "trainer for a day." General admission allows you to observe the dolphins through 6-foot-by-10-foot acrylic windows. The 1.3-million-gallon facility is home to 13 dolphins, and until 2014 the park housed Nellie, the longest-lived dolphin in human care until her death at the age of 61. A new calf, Coquina, was born shortly after Nellie's death. Other exhibits feature native Florida marine life such as tarpon, sharks, spotted eagle rays, and giant sea turtles, as well as historical artifacts dating back to the park's inception as a nautical movie studio.

A 1,000-acre wildlife sanctuary along the Bolinas Lagoon, this Audubon Canyon Ranch preserve gets the most traffic during late spring. Quiet trails through the rest of the preserve offer tremendous vistas of the Bolinas Lagoon and Stinson Beach. On Saturdays, ranch guides are posted throughout to point out animals—including waterbirds, shorebirds, bobcats, and coyotes—and answer questions. During the week, check in at the small bookstore and take a self-guided tour.

One of the largest outfitters in the Las Vegas Valley, McGhie's rents equipment for skiing, bicycling, and sandboarding. This location, in downtown Blue Diamond, which is just west of the city in Red Rock Canyon National Conservation Area (there are others in Henderson and on South Fort Apache in Las Vegas), specializes in bikes—convenient, since it's right on the doorstep of 125 miles of hard-core mountain biking. The company rents bikes individually, and also offers a host of guided tours around Red Rock and beyond. Unlike other outfitters in the area, McGhie's also rents bikes specifically for kids.

In the center of Santa Clara University's campus is the Mission Santa Clara, the site of the first college of higher learning in California (est. 1851). Some of the roof tiles of the current building, a reproduction of the original, were salvaged from earlier structures, which dated from the 1770s and 1820s. Restored original adobe walls (1822) and a spectacular rose garden (viewable, but not open to the public) remain intact as well.

You can partake of the southern Central Valley's agricultural bounty at the farm's Big Red Barn location—owners Steve and Vickie Murray promise more free samples than Costco, and they deliver. You'll find whatever's in season, including peaches, plums, apricots, and 18 cherry varieties. There are prepared foods, too, and activities for kids (jumping pillow, petting zoo, hay rides, AstroTurf sledding hill). The Cal-Okie Kitchen sells tasty fry pies filled with eggs and other ingredients for breakfast and pulled chicken and other meats for lunch and dinner.

Founded in 1888, the National Geographic Society is best known for its magazine, and entering this welcoming 13,000-square-foot exhibition space feels like stepping into its pages. The compact museum offers family-friendly, if pricey, interactive exhibitions delving into the historical, cultural and scientific research that distinguishes National Geographic Magazine. There are items from the permanent collections—cultural, historical, and scientific—as well as traveling exhibitions. It also has a new virtual-reality theater experience introduced in 2018. Nat Geo Nights—presentations by explorers with interactive activities, music, and food and drink specials—are held the third Thursday of every month. The M Street Lobby photography exhibit, as well as the outdoor photo display around the perimeter of the museum, are free.

You can sample the wares at this homey factory complex, which has tastings (try the aged Gouda) and cheese-making tours, a store, and a bakery. Outside are a picnic area and a petting zoo.

Ten miles east of Biddeford lies Ocean Park, a vacation community founded in 1881 by Free Will Baptist leaders as a summer assembly with both religious and educational purposes, following the example of Chautauqua, New York. The 1881 Temple, in an unusual octagon shape, is on the National Register of Historic Places. Today the community hosts an impressive variety of cultural events, from concerts to sand-sculpture contests. There's even a public shuffleboard area for vacationers not interested in the neon carnival attractions in Old Orchard Beach just up the road. Get an old-fashioned raspberry-lime rickey at the Ocean Park Soda Fountain, at Furber Park.

If a quarantine is not in effect (watch for signs), from November through April you can look for mussels amid tidal pools and rocky outcroppings at Pescadero State Beach; a fishing license is required. Any time of year is good for exploring the beach, the north side of which has several secluded spots along sandstone cliffs. Across U.S. 101, the 243-acre Pescadero Marsh Natural Preserve has hiking trails and is the site of a large and active blue-heron rookery. Early spring and fall mornings are the best times to come, when there are lots of migrating birds and other wildlife to see. No pets on the beach or in the preserve. Amenities: parking (fee); toilets. Best for: solitude; sunset; walking.

With its laid-back restaurants (including Half Moon Bay Brewing Company) and waters full of fishing boats and sea lions, the harbor is a nice place to wander, and you can pick up shoreline trails at nearby Pillar Point.

The original Point Montara fog signal station was established in 1875. The lighthouse, which originally stood on Cape Cod from 1881 to 1922, was added in 1928, and it still has its original lightkeeper's quarters from the late 1800s; it's the only known lighthouse to have served on both coasts. Gray whales pass this point during their migration from November through April, so bring your binoculars. Visiting hours (9 am to sunset) coincide with morning and afternoon check-in and checkout times at the adjoining youth hostel. Parking is free, but a one-hour time limit is enforced.

Sequoia sempervirens, or coastal redwoods, grow to 150 feet tall in Redwood Regional Park, one of the few spots in the Bay Area that escaped timber-hungry loggers in the 19th century. The 1,830-acre park has forested picnic spots and myriad hiking trails, including part of the 32-mile East Bay Skyline National Trail, which links Redwood to four other parks in the Berkeley–Oakland hills. Also check out adjacent Joaquin Miller Park for beautiful East Bay views and lush forested trails.

The nation's first Ripley's museum is, appropriately enough, in a historic structure—Castle Warden, an 1887 Moorish Revival–style mansion. Like its younger siblings, this odditorium is packed with plenty of unusual items including Robert Ripley's personal collections; a mummified cat; a death mask of Abraham Lincoln; a scale model of the original Ferris Wheel created from an Erector set; and life-size models of Robert Wadlow, the world's tallest man, and Robert Hughes, the world's fattest man.

Tree-shaded Roeding Park is a place of respite on hot summer days; it has picnic areas, playgrounds, tennis courts, horseshoe pits, and a zoo. A train, little race cars, paddleboats, a carousel, and other rides for kids are among the amusements at Playland. Children can explore attractions with fairy-tale themes at Rotary Storyland.
