This leading ecotourism and conservation wildlife refuge offers spectacular bird-watching tours and excellent naturalist-led hikes (starting at $36), a thrilling Flight of the Toucan canopy tour ($52), a chance to spend the night in the jungle ($158), or self-guided walks along forest and mangrove trails ($15). The refuge also manages a turtle-protection project and nature-education program in the local school. You can stay in basic cabins or in poolside rooms—or just come for the day.

This massive double cascade, the longer one tumbling down 150 feet, is one of the most spectacular sights in Costa Rica. The falls (aka Barú River Falls) are on private property, so the only ways to reach them are on horseback, hiking, or riding in an open truck. Arrive before 1:30 pm as the ticket office closes at 2 and access to the waterfalls closes at 3:30 pm.

With more than 200 specimens, Parque Reptilandia is the largest reptile park in Central America. Their impressive collection includes snakes, lizards, frogs, turtles, and other reptilian creatures, housed in visitor-friendly terrariums and large naturalistic habitats. Stars of the park are a Komodo dragon, a pair of 200-pound Aldabra tortoises, and Coquita the American crocodile. An easy walking trail winds through covered and open-air exhibits and can be visited, rain or shine. The well-planted gardens within the park are a haven for many native bird species. The park is open daily from 9 am to 4 pm.

Long and flat, Playa Dominical is good for beachcombing among all the flotsam and jetsam that the surf washes up onto the brown sand. There's shade and parking under palm trees along the brick-paved road that parallels the beach. Along the stretch between the road and the waves, you'll find local artisans selling artwork and sarongs flapping the breeze. The water is relatively clean and local businesses make sure things look tidy. Tortilla Flats restaurant is practically on the beach. Huge waves and dangerous rip currents make it primarily a surfing beach. In high season, flags mark off a relatively safe area for swimming, under the watchful gaze of a professional lifeguard. Amenities: food and drink; lifeguards; parking (no fee). Best for: surfing; walking.

This wide beach is usually calmer and more suited to boogie boarding and beginner surfers. There are hidden rocks near the shore, so the best time to swim is at low tide. This is one of the best walking beaches, with lots of shade under tall palms and beach almond trees early in the morning. The sun sets behind a huge rocky outcropping topped with tiny palm trees, an ideal shot for photographers. There is an unofficial campground running parallel to the beach, which is popular with locals, especially during Easter, Christmas, and school holidays. Amenities: parking (no fee). Best for: solitude; sunset; walking.

Hidden in a forest above Dominicalito Beach, this waterfall is considerably smaller than Nauyaca Waterfalls, but it has a lovely swimming hole at its base. The pool is often populated by local kids when school is out and by surfers late in the afternoon. Pay strict attention to the posted sign that warns not to leave anything of value in your parked car. Avoid holiday times and weekends, when there are often large crowds. The best time to visit is during rainy season between the months of June and December, but be mindful of stairs that are steep and often slippery.
