Reserva Esperanza Verde

Lodge in Refugio de Vida Silvestre Los Guatuzos

Nestled on the Río Frio, roughly halfway between San Carlos and Los Chiles, is this private, 5000-hectare humid tropical forest reserve. Expect to see hundreds of bird species, three kinds of monkeys, fingernail-sized tree frogs, and an array of rare orchids. You can do it in a day trip from San Carlos (US$30 per person, two-person minimum), including private panga transport, guide and trail access, which can be arranged through Hotel-Cabinas Leyko in San Carlos. Alternatively, you can spend the night in one of its simple, solar-powered rooms.
