West of Guápiles, in a secret volcanic-mountain-range location, a 45-minute 4WD trip and a three-hour hike lead to this fabulous 410-hectare rainforest reserve (altitude 800m), set in a Parque Nacional Braulio Carrillo buffer zone. You'll sleep in an atmospheric lodge with no electricity. Rates include transport from Guápiles, meals, jungle hiking, wildlife-spotting and splashing in nearby rivers. Reserve ahead.
There's a minimum of six people and a maximum of 12.
