Río San Juan: river journeys, history and nature
Río San Juan is a river region where San Carlos, El Castillo, Solentiname and the Indio Maíz conservation area require different travel arrangements. River transport is central to planning many experiences.
What to see and do
Explore San Carlos as a gateway, consider the historic fortress in El Castillo or a separate journey to the Solentiname archipelago. Nature experiences near Indio Maíz must follow current access and conservation rules.
How to get around
Identify the exact river destination and departure dock before arranging boats. The route to El Castillo is not the same as the journey to Solentiname, and lodges downstream may require an additional arranged transfer.
Before you travel
Allow generous time for boat schedules, weather and connections. Do not assume a lodge provides transfers or guided activities without confirmation, and respect protected-area restrictions.
