Boat Logistics
Confirm lancha departure times to Solentiname or El Castillo early in the morning, as schedules can be infrequent.





San Carlos sits at the southeastern corner of Lake Nicaragua, marking the start of the historic San Juan River. As a major administrative and transport center, it is the primary link between the mainland and the remote wonders of the Río San Juan Department. While many visitors treat it as a transit point, the town offers an authentic look at Nicaraguan life with its bustling docks and local commerce. It is the best place to arrange boat transport to the Solentiname Islands, known for their primitive art and birdlife, or to head downstream toward the fortress of El Castillo. The town also provides access to the Los Guatuzos Wildlife Refuge, a haven for biodiversity.
