Major city · Nicaragua
San Carlos
Stay 1 night, 2 if you want the fort and a boat day: San Carlos is a river-boat junction, not a destination. Base on the malecón.
San Carlos sits where Lake Nicaragua drains into the Río San Juan, in the country's wet south-east. Almost every traveller passes through on the way to El Castillo, the Solentiname Islands or the Costa Rica border at Los Chiles. The malecón and the old fort take half a day; the rest of your time is boats, buses and stocking up before the road ends.

- Central America ↗Guatemala, El Salvador, Honduras and Nicaragua (CA-4) give one shared entry allowance, usually 90 days in total; leaving for Belize, Costa Rica or Mexico and coming back does not always reset it — check with immigration before a long stay.
- Central America ↗Cross land borders in daylight and early in the day; many posts close or empty of transport by late afternoon, and the approaches are where robberies happen.
- Central America ↗Several borders charge entry, exit or municipal fees in US dollars (Belize exit, Nicaragua entry and exit, Honduras entry); carry small, clean US notes and ask for a receipt.
- Nicaragua ↗Check entry rules for your passport with a Nicaraguan embassy and your airline before booking; some visitors must register in advance, and entry can be refused without explanation.
- Nicaragua ↗Avoid political gatherings and do not photograph police, the military or protests; foreign nationals have been detained or expelled.
- Nicaragua ↗Do not bring drones or professional camera equipment without prior permission; they can be confiscated at customs.

Watch out
Safety
- Boat and bus timetables change often: confirm at the ticket office the day before.
- Do not photograph the armed border post on the Río Frío boat to Los Chiles.
- Street money-changers: use a bank or a shop, and count the notes.
- Take a taxi after dark rather than walking long distances.
- Swimming off the malecón is what locals do, but the lake takes untreated sewage: use a piscina instead.
