Central America entry requirements

By the Viamo editorial team · Editor Terje Moy · Last updated July 2026 · 7 min read

Central America spans seven countries with distinct entry rules — but the region has made overland travel considerably more straightforward than it looks on paper. Mexico's visitor card system, the CA-4 free-movement agreement covering four countries, and slightly stricter requirements in Costa Rica and Panama together shape what most travellers actually need. Here is how it all works.

Mexico: the FMM visitor card

Mexico is not part of Central America geographically, but most overland journeys through the region begin here. Visitors arriving in Mexico from countries that do not require a Mexican visa are issued a Forma Migratoria Múltiple (FMM) — a visitor card that grants a tourist stay of up to 180 days.

If you arrive by air, the FMM fee is typically included in your airline ticket. If you cross a land border, you pay a fee at the border post — currently in the range of a few hundred Mexican pesos, though the exact amount can change. Keep the paper FMM stub carefully; you must surrender it when you leave. Losing it can cause delays at departure and may result in a fine.

Mexico does not require an onward ticket for most nationalities, but individual immigration officers have discretion, and having evidence of onward travel is always sensible. For a detailed look at visa requirements by nationality, see our guide to do I need a visa.

The CA-4 agreement: Guatemala, El Salvador, Honduras, Nicaragua

The CA-4 Border Control Agreement allows citizens of Guatemala, El Salvador, Honduras and Nicaragua — and qualifying foreign visitors — to move freely between these four countries without completing separate immigration formalities at each border. In practice, this means that once you are admitted into any one of the four CA-4 countries, your allowed stay runs across all four collectively.

For most tourists from visa-exempt countries (including the UK, US, Canada, Australia and the EU), the CA-4 grant is 90 days total across all four countries combined — not 90 days per country. Crossing from Guatemala into Honduras, for example, does not reset your clock.

Key practical points:

• You still cross through border posts and your passport is stamped, but the immigration process is simpler than a full new visa procedure.
• The 90-day CA-4 allowance begins from your first entry into any of the four countries.
• If you exit the CA-4 zone entirely — for example by visiting Costa Rica or Mexico — and then re-enter, a new 90-day period may begin, though this can be inconsistently applied. Immigration practice at individual land borders is not always uniform.
• Some nationalities are not visa-exempt even under CA-4 and need to apply for a visa in advance. Check carefully for your specific passport.

Land borders within the CA-4 zone can be busy and bureaucratically variable. Keep photocopies of your passport and entry stamps, and allow extra time at major crossings such as La Hachadura (El Salvador–Guatemala) or El Florido (Guatemala–Honduras).

Guatemala

Citizens of many countries — including the US, UK, EU nations, Canada, Australia and Japan — enter Guatemala visa-free for up to 90 days (within the CA-4 framework). No onward ticket is officially required, but border officers may ask. There is no tourist entry tax at most land borders, though fees can apply at international airports.

El Salvador

Entry rules broadly mirror Guatemala's within the CA-4 framework. El Salvador uses the US dollar as its currency and has moved toward digital payment systems in some areas following its Bitcoin legal-tender legislation, though cash in dollars remains universally accepted at borders. No tourist card fee applies for most visa-exempt visitors, but verify this for your nationality.

Honduras

Honduras participates fully in CA-4. A tourist entry fee — historically in the range of US$3–5 — is collected at some land borders; the exact amount and applicability vary. Keep small US dollar bills for border crossings. The land border at El Florido (connecting to Copán Ruinas, one of the great Mayan archaeological sites) is frequently used by travellers.

Nicaragua

Nicaragua also participates in CA-4 but historically has charged a tourist card fee upon entry — around US$10 at land borders, payable in US dollars. This has varied over the years, so confirm the current amount before you arrive. Some nationalities require a visa in advance; others are granted 30-day tourist entries. Political conditions in Nicaragua have been volatile in recent years; check your government's travel advice carefully before visiting.

Costa Rica: onward ticket and proof of funds

Costa Rica sits outside the CA-4 agreement and enforces its own entry rules. It is one of the stricter countries in the region for immigration checks:

• Onward ticket: Costa Rican immigration typically requires proof of an onward or return ticket. This is checked at the airport and can be enforced at land borders. Airlines will sometimes deny boarding if you cannot show this. Booking a refundable bus ticket onward to Panama or an open-return flight is a common workaround for open-ended travellers.
• Proof of funds: Immigration may ask for evidence that you can support yourself during your stay — generally around US$100 per person per day is cited, though this is rarely verified with bank statements in practice. Having a credit card and some cash available is usually sufficient.
• Visa-exempt stays: Most Western passport holders receive 90 days. Costa Rica is popular and well set up for tourists; the rules are enforced but the process is generally smooth for most visitors.

Panama: onward ticket, entry and the Darién Gap

Panama also requires an onward or return ticket and proof of sufficient funds (often cited as US$500 or equivalent, or a credit card). These requirements are genuinely enforced, particularly at Tocumen International Airport in Panama City.

Panama grants 90-day tourist entries to most visa-exempt nationalities. The country is used by many travellers as the southern gateway, particularly those arriving by air for onward connections to South America.

One critical point for overland travellers: there is no road through the Darién Gap between Panama and Colombia. The Pan-American Highway breaks here. To continue from Central America to South America by land is not possible via the gap itself; travellers either fly or take a boat (via the San Blas Islands or Capurgana). This is one of the most significant route breaks in the Western Hemisphere and should be planned in advance. See our guide to coaches in South America for onward planning once you reach the continent.

Border crossing fees: a general note

Various fees are collected at Central American land borders — exit taxes, entry fees, tourist cards, municipal taxes — and the situation changes frequently. Some fees are official; some are informal requests. In general:

• Carry US dollars in small denominations (US$1, US$5, US$10) for fees at all borders.
• Fees of US$1–15 at various borders are normal; anything significantly higher warrants scrutiny.
• Unofficial "helpers" at busy crossings will offer to guide you through for a tip — you are not obliged to use them, but at chaotic border posts they can save time.
• Get receipts where possible for any fees paid.

Frequently asked questions

What is the CA-4 agreement and which countries does it cover?

The CA-4 Border Control Agreement allows qualifying visitors to move freely between Guatemala, El Salvador, Honduras and Nicaragua. Most visa-exempt tourists receive a single 90-day allowance across all four countries combined, not 90 days per country.

Do I need an onward ticket to enter Costa Rica?

Yes, in practice. Costa Rican immigration routinely requires proof of a return or onward ticket. Airlines check this at check-in for flights to Costa Rica, and land border officers may ask too. Have documentation ready.

How much is the Mexico FMM tourist fee?

The FMM fee at land borders is typically a few hundred Mexican pesos (roughly US$15–20 at recent exchange rates), though it is subject to change. At airports it is usually included in the airline ticket. Keep your FMM stub — you must return it when you exit.

Can I drive from Panama to Colombia through the Darién Gap?

No. There is no road through the Darién Gap. Travellers must fly or take a boat between Panama and Colombia. This break in the Pan-American Highway is a fundamental logistics consideration for anyone travelling overland through the Americas.
