20 Best Sights in Yellowstone National Park, Wyoming

On a busy day in summer, only a handful of parties will fill out the trail register at the Avalanche Peak trailhead, so if you're seeking solitude, this is your hike. Starting across from a parking area on the East Entrance Road, this rigorous 4.2-mile, four-hour round-trip climbs 2,150 feet to the peak's 10,566-foot summit, from which you'll see the rugged Absaroka Mountains running north and south. Look around the talus and tundra near the top of Avalanche Peak for alpine wildflowers and butterflies. From early September to late June, the trail is often impassable due to snow, and fall also can see grizzly bear activity. Stick to summer. Difficult.

Past the entrance to Bunsen Peak Road, this moderately challenging 4.4-mile round-trip trek climbs 1,280 feet to 8,527-foot Bunsen Peak for a dramatic panoramic view of Blacktail Plateau, Mammoth Hot Springs, the Gallatin Mountains, and the Yellowstone River valley. Allow about three hours.Moderate–Difficult.

A 2-mile round-trip route leaves Geyser Hill Loop boardwalk and becomes a trail shortly after the Firehole River; it circles a picturesque overview of Geyser Hill with Old Faithful Inn as a backdrop. You may also see Castle Geyser erupting. Even when 1,000-plus people are crowded on the boardwalk to watch Old Faithful, expect to find fewer than a dozen here. Easy–Moderate.

Partly paved and fairly flat, this 1¾-mile trail along the south rim of the Grand Canyon of the Yellowstone affords impressive views and photo opportunities of the canyon and falls of the Yellowstone River. It starts at Chittenden Bridge, passes by magnificent Upper Falls View and Uncle Tom's Trail, and ends at Artist Point. Beyond Artist Point, you can continue your adventures for another 1.3 miles along a less-traveled and stunning trail to Point Sublime, or cut inland through high mountain meadows along the Clear Lake–Ribbon Lake Loop. You'll see fewer humans and possibly more wildlife in this more rugged backcountry, so carry bear spray. Moderate.

You can hike these two easy loops, which both leave from the Norris Ranger Station, in under two hours. The 1½-mile Back Basin loop passes Emerald Spring, Steamboat Geyser, Cistern Spring, and Echinus Geyser. The latter was long known as Norris's most dependable big geyser, but its schedule has become much more erratic. The ¾-mile Porcelain Basin loop leads past whitish geyserite stone and extremely active Whirligig and other small geysers. Easy.

This 2½-hour, 5-mile loop starts at Liberty Cap in the busy Lower Terrace of Mammoth Hot Springs. Within minutes you'll find yourself amid the park's dense backcountry as you climb 400 feet through spruce and fir, passing several ponds and dams, as well as a glacier-carved moraine, before emerging on a windswept plain overlooking the Montana–Wyoming border. Look up to see Everts Peak to the east, Bunsen Peak to the south, and Sepulcher Mountain to the west. Your final descent into Mammoth Springs has great views of Mammoth Springs. Moderate.

Especially scenic, this short but steep jaunt branches off of the North Rim Trail and can be accessed from either the Brink of the Upper Falls or Brink of the Lower Falls parking areas. The ½-mile one-way trail switchbacks 600 feet down to within a few yards of the top of the Yellowstone River's 308-foot Lower Falls. Moderate.

Ranger-led walks are held at various locations throughout the summer. Winter programs and some walks are held at West Yellowstone, Old Faithful, and Mammoth. Check the website or park newspaper for details.

Take the ½-mile loop boardwalk to see the fumaroles (steam vents), blue pools, pink mudpots, and mini-geysers in this thermal area. The trail is popular, and sometimes a bit overcrowded, in summer and winter because it's so accessible. Easy.

Along the easy 1.3-mile Geyser Hill Loop boardwalk, accessed from the Old Faithful Boardwalk, you'll see active thermal features such as violent Giantess Geyser. Erupting only a few times each year (but sometimes going quiet for several years), Giantess spouts from 100 to 250 feet in the air for five to eight minutes once or twice hourly for a few to as long as 48 hours. Nearby Doublet Pool's two adjacent springs have complex ledges and deep blue waters that are highly photogenic. Starting as a gentle pool, Anemone Geyser overflows, bubbles, and finally erupts 10 feet or more, every three to eight minutes. The loop boardwalk brings you close to the action, making it especially fun for kids.

This 0.6-mile loop hike in Hayden Valley curves gently around seething, sulfuric mudpots with such names as Sizzling Basin and Black Dragon's Cauldron, and around Mud Volcano itself. Easy.

From the west end of Biscuit Basin boardwalk, this 2.4-mile round-trip trail climbs gently for a mile through heavily burned forest to the lava-rock base of 70-foot Mystic Falls. It then switchbacks up Madison Plateau to a lookout with the park's least-crowded view of Old Faithful and the Upper Geyser Basin. Easy–Moderate.

Offering great views of the Grand Canyon of the Yellowstone, the 3-mile (each way) North Rim Trail runs from Inspiration Point to Chittenden Bridge. Particularly fetching is the ½-mile section of the North Rim Trail from the Brink of the Upper Falls parking area to Chittenden Bridge that hugs the rushing Yellowstone River as it approaches the canyon. This trail is paved and fully accessible between Lookout Point and Grand View, and it can be accessed at numerous points along North Rim Drive. Moderate.

Starting at Slough Creek Campground, this trail climbs steeply along a historic wagon trail for 1½ miles before reaching expansive meadows and prime fishing spots, where moose are common and grizzlies occasionally wander. Allow two or three hours for the full 3.4-mile round-trip hike. Moderate.

Well marked and mostly flat, this 2.3-mile loop leaves the south side of the road for a perfect beginner's hike out to Yellowstone Lake, particularly with a setting sun. The trail rounds the western edge of Indian Pond, then passes moose habitat on its way to Yellowstone Lake's Storm Point, named for its frequent afternoon windstorms and crashing waves. Heading west along the shore, you're likely to hear the shrill chirping of yellow-bellied marmots. Also look for ducks, pelicans, trumpeter swans, and bison. You'll pass several small beaches that kids enjoy exploring. Easy.
