IMPORTANT! Starting August 1, 2023, the national park will require all visitors to purchase park tickets online beforehand on the SINAC website. They will stop selling park tickets at the door on August 1. Rio Celeste hiking level is moderate. The trail is not terribly long or difficult but for inexperienced hikers, some sections may prove a little challenging, particularly the waterfall. There are around 150 or so steep steps to the waterfall. Additionally, there are many big rocks and tree roots you have to walk on as it’s a natural path. Sometimes when the rains are incredibly heavy or there is a tropical storm, the river isn’t blue. This normally occurs during the months of September, October and November. December can be very rainy too.
