There are around 500 rivers in Panama. They generally start from steep mountains, making Panama one of the best places to raft. Rafting is practised mainly in the province of Chiriqui on the River Chiriqui Viejo. Professional rafters can say that the Chiriqui Viejo is one of the best white water rafting rivers with relatively easy access.
The river is 130 km long and is located near Costa Rica. While rafting, you can see beautiful mountain towns of Cerro. By the way, if you're planning to go rafting on Chiriqui please take into account the tropical rainy season that lasts from May to December, with its peak in September through October. The more convenient dry season in Panama lasts from January to May and is more suitable for calm rafting enthusiasts.
