Every campamento offers guided walks, or caminatas, through the rainforest to nearby sights, typically lasting 3–5 hours and costing US$25–40 per person.
Ruínas Lacanjá (Lancanjá Ruins) is a minimally excavated archaeological site, with a small main temple with traces of the original red paint still visible and several inscribed panels and stelae, ensconced in lush rainforest.
Cascada Las Golondrinas [1] (Swallows Waterfall) is a scenic waterfall made up of four different cascades, pouring over a long cliff. While included in most guided walks, it’s easy enough to reach on your own, following a trail accessed through Parador Sak Nok’ (US$3.50 entrance).
Campamento Río Lacanjá [2] arranges rafting trips (US$60 pp) that include two hours rafting down the Río Lacanjá and two hours hiking back, with stops at Lacanjá ruins and Cascada Las Golondrinas [1].
Laguna Lacanjá is described by some as a mini–Laguna Miramar [3]; it’s a gorgeous crystalline lake emerging like an oasis from the lush tropical rainforest. Unfortunately, a disagreement between local residents has halted visits there, at least officially. Still, it doesn’t hurt to ask—it’s a true gem, and all the more memorable for being so seldom visited.
