Land Border Crossings

Before every land crossing — what to have ready

Passport open to the bio pageA closed passport is the most common reason for a queue delay — have it open before you reach the window.

A pre-arranged visa or eVisa, where one's requiredKenya, Vietnam and several other crossings on this page have dropped visa-on-arrival in favor of an eVisa arranged online in advance — check which your route needs before you're at the window.

Local currency (often USD) for on-the-spot feesVisa-on-arrival fees, exit taxes and departure charges are usually cash-only at the booth. Laos and Cambodia both run on exact-change USD.

A passport photoStill required for Lao and Cambodian visas on arrival — carry two spares so a missing photo doesn't cost extra at the counter.

Proof of onward travel or your first night's addressPanama and several other posts ask for it — a screenshot of a booking is normally enough.

A real time bufferPeak-hour waits run 1–2+ hours at busy posts like San Ysidro and Namanga. Never schedule a connecting bus or flight right after a border crossing.

Europe — Schengen zone exits & re-entries The 90/180-day rule applies across Schengen — see Visa Processing Times

Bregenz/Höchst — Lustenau

Austria ↔ Switzerland

5–20 MIN CAR / BUS ON FOOT

One of the quieter Schengen crossings into Switzerland (which is Schengen but outside the EU customs union). Passport control sits on the Swiss side; Austria stamps on request. Friday afternoons add up to 40 minutes from commuter traffic.

Horgos / Röszke

Serbia ↔ Hungary (Schengen)

1–5 HRS PEAK CAR BUS

The busiest Schengen entry point in the Balkans. Bus passengers are processed separately from cars and usually move faster. Arriving before 07:00 or after 20:00 can cut the wait to under 30 minutes.

Serbia is outside Schengen — the same Schengen visa or authorization that covers Hungary is required here, not a separate one.

Southeast Asia — the overland circuit Thailand / Laos / Cambodia / Vietnam

Thailand's land border with Cambodia has been closed since mid-2025 — including Poipet/Aranyaprathet, the main Bangkok–Siem Reap crossing — after a border dispute escalated into armed conflict. As of 2026 there is no confirmed reopening date; an overland Thailand–Cambodia route currently isn't possible, and flying is the only way between the two. Confirm current status before routing a trip through it.

Nong Khai — Vientiane (Friendship Bridge)

Thailand ↔ Laos

10–30 MIN BUS TRAIN

A shuttle bus crosses the 1.2km bridge every 10–15 minutes (40 baht); two direct trains a day also run to Vientiane's Khamsavath station. Lao visa on arrival costs $20–42 in cash depending on nationality, plus $1 if you don't have a photo. Open 06:00–22:00.

Moc Bai — Bavet

Vietnam ↔ Cambodia

30–60 MIN BUS

The direct Ho Chi Minh City–Phnom Penh bus route (~6–7 hrs); the operator collects passports and walks the bus through both sides. Cambodia visa on arrival is $30 cash; Vietnam requires an eVisa arranged at least a few days ahead for every nationality.

East Africa — safari-circuit border posts Kenya / Tanzania / Uganda — the East African Community (EAC)

Namanga

Kenya ↔ Tanzania

30 MIN–2 HRS CAR / BUS

The main Nairobi–Arusha overland link and the busiest post on this circuit, worse during June–October safari season. Tanzania's eVisa runs $50 single-entry / $100 multiple-entry; Kenyan citizens cross visa-free under the EAC agreement. A yellow fever certificate is required if arriving from an endemic country. Open roughly 06:00–22:00.

Kenya ended visa-on-arrival in January 2025 — non-Kenyans need the eVisa arranged online before arriving, not at the booth.

Busia

Kenya ↔ Uganda

UNDER 1 HR TYPICAL CAR / BUS ON FOOT

A one-stop border post — both countries' agencies share a single building, which runs faster than the older two-checkpoint layout — and it's open 24 hours. Kenya entry issues the East Africa Tourist Visa's free interstate pass at the booth; Uganda requires an eVisa arranged in advance, with no visa on arrival.

The Americas

San Ysidro

Mexico ↔ United States

45 MIN–2+ HRS CAR ON FOOT

The busiest land border crossing in the Western Hemisphere (Tijuana ↔ San Diego). The three vehicle lanes run at very different speeds: General is slowest, Ready Lane typically trims 15–35 minutes off it, and pre-approved SENTRI can run under 15 minutes. Peak hours are 06:00–10:00 and 16:00–20:00. Live waits: bwt.cbp.gov ›

Paso Canoas

Costa Rica ↔ Panama

30 MIN–1.5 HRS CAR / BUS ON FOOT

One of Central America's busiest and least organized crossings — long lines and paperwork checks on both sides. Costa Rica charges an $8 exit tax, payable at a kiosk across from the border office, before you're stamped out. Panama entry requires proof of onward travel; most nationalities pay no visa fee for stays up to 180 days.

Universal crossing tips

Never bribe

An officer asking for an unofficial "fee" is testing you. A calm "What's the official receipt for this?" usually ends it — most low-level corruption at a crossing relies on travelers not asking.

Exit stamp first

At crossings where you walk between two buildings, get the exit stamp before approaching the other country's entry booth. A missing exit stamp is one of the most common reasons travelers get turned back.

Bus vs. own transport

A shared bus can be slower into the queue but faster through it — the operator coordinates directly with officials on both sides. A private car or taxi only skips the line at minor crossings; at major ones it queues separately and often waits longer.

Check the hours

Most land crossings run roughly 06:00–22:00; a few, like Busia, are 24 hours, and some remote posts close for lunch or by 18:00. Confirm the specific crossing's hours before building it into a tight itinerary.
