A low rumble of the 4x4, a sweep of green that opens toward the Pacific—this is how the day begins leaving San José for the Tarcoles valley. Riders crest a mountain and the ocean glints below; the truck drops you at a riverine edge where mangroves and escarpments line a waterway famous for large American crocodiles.
