Do Finland passport holders need a visa to visit GT?

Finnish ordinary passport holders do NOT need a visa for tourism in Guatemala. Finland is a "Category A" country, so travelers receive a free entry stamp on arrival permitting a stay of up to 90 days within a 180-day period. This 90-day allowance is shared across the CA-4 zone (Guatemala, El Salvador, Honduras, Nicaragua). Finland is classified by the Instituto Guatemalteco de Migración as a "Category A" country whose nationals are exempt from any visa to enter Guatemala. On arrival, a Finnish citizen receives a passport stamp granting up to 90 days for tourism, business, or transit, free of charge. Because Guatemala is part of the Central America-4 (CA-4) Border Control Agreement, the 90-day clock covers combined time spent in Guatemala, El Salvador, Honduras, and Nicaragua, and begins on first entry to any of the four. The stay can be extended once for a further period at the immigration offices in Guatemala City. The passport must be valid for at least six months on arrival. Immigration officers may request proof of onward/return travel, accommodation details, and sufficient funds. Guatemala is in Central America, not the Schengen area, so the EU Schengen 90/180 rule and ETIAS do not apply to this route (ETIAS is a European scheme affecting travelers entering the EU, not Finns leaving it). Verdict is firmly visa-free, confirmed against the Guatemalan immigration authority, the Finnish Ministry for Foreign Affairs listing, and the published visa policy.
