- 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.
El Castillo is a one-street river village on the San Juan, built around a 1670s Spanish fort that once stopped pirates and Horatio Nelson. There are no cars, no ATM and no road in: you arrive by boat from San Carlos, walk everywhere, and use the village as a base for Indio Maíz rainforest and river rapids. Two nights covers the fort, a jungle or kayak day and the boat back.
