Térraba–Sierpe Wetland Reserve [1]: This vast mangrove ecosystem teeming with wildlife can be explored by boat from Sierpe and Ojochal.
Drake Bay [2]: A dramatic setting close to Corcovado and Caño Island adds to the appeal of this hidden corner, where nature lodges specialize in sportfishing and diving. A nighttime insect tour is guaranteed to be fascinating and educational. It’s accessible by an improved road, but drivers will still need to ford three rivers.
Corcovado National Park [3]: Jaguars, tapirs, crocodiles, colorful snakes, and monkeys and scarlet macaws galore are among the easily seen wildlife in this rugged rainforest reserve. Numerous lodges and tent-camps nearby grant access.
Casa Orquídeas [4]: Ron and Trudy McAllister have spent more than two decades creating this amazing botanical garden, tucked away on the remote shores of Golfo Dulce.
Playa Zancudo [5]: A magnificent beach and dramatic setting combine with low-key accommodations to provide a lazy, laid-back retreat where all you need is a hammock and swimwear.
Pavones [6]: This surfers’ paradise has it all: great waves, stupendous palm-shaded beaches, and plenty of budget options for eats and places to rest your head. Tiskita Lodge is a rustic delight for nature lovers.
Isla del Cocos National Park [7]: This remote isle is off-limits to all but experienced scuba divers, who come to commune with pelagic creatures, including whale sharks, rays, and hammerhead sharks.
Paradise Garden [8]: You’ll learn fascinating lore about plants, including their medicinal qualities, at this tropical garden lovingly tended by its North American creator and owner.
