For eco-tourists who crave adventure there are few places better than Parque Nacional Corcovado, a biodiverse smorgasbord of tropical rainforest, coastline and wildlife. Puerto Jimenez is a great base for those who wish to explore the park via one of several local touring companies, but it’s also got its own thing going on, including an impressive wildlife sanctuary, some lovely restaurants and an excellent local crafts shop.

Legend has it that notorious pirate Sir Francis Drake hid his treasures somewhere in Drake Bay, hence the name. Doubloons or not, there are plenty of natural treasures to marvel over, like lush rainforests and colorful sea life. Invest in a guided hiking, diving, fishing, tubing or treetop canopy tour to get the full Drake Bay experience. “Tracie the Bug Lady” even offers a night tour to acquaint you with all of the local creepy crawlies.

You can easily fill a week with activities in and around the mountain village of Boquete. Tours of every sort—jungle tours, coffee estate tours, hiking tours.

A tiny village with two miles of pure white sand and fabulous conditions for swimming, Uvita might become your favorite place in Costa Rica. It's part of the Marino Ballena National Park (Whale Marine Park), named for humpback whales who meet and mate here every winter and spring. Take a boat ride to Caño Island, a nature reserve with incredible marine life.

Surf, dive, snorkel, beach comb, horseback ride, bicycle, or relax in a hammock in Dominical. Take a stress-relieving yoga class at Bamboo YogaPlay. Enjoy beach restaurants serving up everything from East Indian curries and Italian pastas and pizzas to local gallo pinto and shots of anise-infused sugarcane liquor. Savor lonely beaches populated by pelicans, frigate birds, brown boobies, and hardy surfers here for the waves and good beachfront food at reasonable prices. When you’ve caught up on your sleep and feel relaxed, take the family on a hike to the double-cascade waterfall at Nauyaca. Perhaps the family would be up for a horseback gallop on the beach, or a trot to a smaller waterfall like Pazo Azul, whose plunge pool is popular with local kids. There is always boogie boarding at Playa Dominicalito. Or beachcombing and dolphin-watching at Playa Dominical. Guided bird-watching, and mangrove estuary and rainforest tours are always educational. Charter a fishing boat. Catch and release big sailfish like marlin in the deep sea, or keep some tasty dinner fish like red snapper, yellowfin tuna, snook, wahoo, and dorado. In Marino Bellena National Park, humpback whales migrate south towards Dominical to escape the Arctic cold. December to April is the humpback whale mating season in Ballena (Whale) Marine National Park. May to November is the nesting season, when Olive Ridley and Hawksbill turtles do their nocturnal egg-laying on the beaches. Low tide beach combing walks can take you out to Punta Uvita Tombolo island. Snorkel, dive, and explore mangrove habitats. Or just sit with the family on the gold and white sands watching green marine iguanas sunbathe between dives into the rocks and corals to feed on marine algae.
