The Refugio de Vida Silvestre La Flor, 19km south of San Juan del Sur, is a guarded reserve dedicated to protecting the sea turtles, primarily the Olive Ridley species, that nest here in large numbers between July and February. The night-time nestings themselves are an amazing spectacle, and the reserve also has good surf, a beautiful white sandy beach and a stand of shady trees, plus more great empty beaches within walking distance. Most hostels and operators can organize a trip here from San Juan – getting here independently (either via one of the water-taxis opposite Hostel Estrella, or by bus from the main stop) can be tricky and you’re best asking in town for frequencies. Mosquitoes and sandflies are abundant – take repellent. Camping overnight (there are a few tents here to rent) is an expensive C$500 per tent.
