Parque El Gallineral

Colombia's official tourism site counts nearly two thousand trees on the island, many draped in Spanish moss. Stone paths and little bridges loop through them, the river is never out of earshot, and because the park is big for its visitors you can usually find a quiet corner to read or just sit.

The municipal institute that runs it lists a pool for adults and children and a restaurant with Santander food. The Fonce rafting trip finishes at the Malecón right beside the park, so it's a natural place to dry off after the river. There's an entry fee, and foreign visitors pay a different rate from locals.
