How long to spend in each country in Southeast Asia
The overnight bus from Hanoi pulls into Ninh Binh just after dawn. The karst towers emerge from low mist, the rice paddies are still dark green, and the only sound is a woman cycling past with two crates of lychees balanced on her rack. You have four days here. It feels exactly right. Two days earlier, in Ha Long Bay, four days felt like two too many.
That tension — too much time in one place, not enough in another — is the central planning problem of any Southeast Asia trip. Most itineraries either sprint through seven countries in three weeks or linger in Thailand so long that Laos becomes a rushed afterthought. Neither is wrong, exactly. But both are worth thinking through before you buy a single flight.
What follows is a country-by-country guide to realistic minimum and comfortable durations, with honest caveats about what actually eats your time: visa queues at border crossings, slow buses on mountain roads, rainy season flooding, and the particular exhaustion of moving every two days.
Thailand: 10–21 days
Thailand is the easiest country in the region to move through efficiently — good roads, reliable trains, a functioning airport network — and also the easiest to overstay in Chiang Mai cafés. A practical skeleton: 3 nights in Bangkok (Rattanakosin for the temples, Chinatown on Yaowarat Road for dinner — try the braised duck over rice at T&K Seafood), then a direct overnight train north to Chiang Mai (12–13 hours, 3rd-class fan sleeper around 300 THB), 3–4 nights, then a decision: islands south or mountains/Laos border north. Don’t try to do both on a trip under 18 days. The Gulf islands (Ko Tao, Ko Samui) and Andaman coast (Krabi, Ko Lanta) are a full sub-itinerary on their own.
Minimum: 10 days. Comfortable: 14–18 days.
Vietnam: 14–21 days
Vietnam is long and narrow — 1,650 km from Hanoi to Ho Chi Minh City — and that geography punishes rushed itineraries. The open-bus ticket (sold everywhere, roughly $35–55 USD for the full route) sounds convenient but deposits you in tourist hubs at inconvenient hours. The train is slower but far saner: the Reunification Express links Hanoi to Saigon with stops at Da Nang, Hue, and Nha Trang. Book soft-sleeper berths on Vietnam Railways at least a week ahead.
Key time sinks: Hoi An needs 3 nights minimum — the tailors, the morning market at Hoi An Central Market, the cycle out to An Bang Beach. Hue needs 2 nights to see the Citadel and at least one meal of bún bò Huế (spicy beef noodle soup, sharper and darker than anything you’ll find elsewhere in the country). Ninh Binh is 2 nights, not one. The north — Sapa, Ha Giang loop — is a week in itself if you want it properly.
Minimum: 14 days (north to south, no detours). Comfortable: 18–21 days.
Cambodia: 7–10 days
Most people spend 3–4 nights in Siem Reap for Angkor, which is correct — the temple complex is vast enough that a single day is a waste of the journey. Sunrise at Angkor Wat is worth the 4:30am wake-up exactly once; after that, go mid-morning when the crowds thin and the light is better for the bas-reliefs at Bayon. Allocate a day for Banteay Srei (37 km northeast, best by tuk-tuk, 600 THB return).
Phnom Penh deserves 2 nights, not the single rushed afternoon many people give it. The Tuol Sleng Genocide Museum and Choeung Ek are emotionally heavy — don’t combine them in one day. The south coast (Kampot, Kep) adds 3–4 days if you want to decompress. Kep’s crab market at the seafront serves crab with Kampot pepper — this is not an optional experience.
Minimum: 7 days. Comfortable: 10–12 days.
Laos: 7–14 days
Laos is slow by design and by infrastructure. The Luang Prabang to Vientiane route by boat (the slow boat down the Mekong from Huay Xai, 2 days) or the Chinese-built railway (3.5 hours, around 200,000 LAK) defines your options. The slow boat is genuinely beautiful — the Mekong narrows and widens between limestone bluffs — but two days on wooden benches is a commitment. Bring a cushion and snacks from Huay Xai market.
Luang Prabang needs 3–4 nights. The alms-giving ceremony (tak bat) at dawn on Sakkaline Road is still worth seeing, though the tourist crowding has worsened — stand back and observe rather than participating directly. Vang Vieng has cleaned up from its party-town nadir and the karst cycling routes around Pha Ngeun Cave are genuinely good. Allow 2 nights. Vientiane: 2 nights is sufficient.
Minimum: 7 days. Comfortable: 10–14 days.
Myanmar: Currently not recommended
The political situation since the 2021 coup remains serious. Most Western governments maintain “reconsider travel” or “do not travel” advisories as of 2026. If this changes, budget 14 days minimum — the Bagan–Inle Lake–Mandalay triangle is the logical core. For current guidance, check your government’s official travel advisory.
Malaysia: 7–10 days
Malaysia is frequently skipped or rushed, which is a mistake. Penang (specifically Georgetown’s Armenian Street and the Clan Jetties in Weld Quay) is one of the finest food cities in Southeast Asia — char kway teow at Penang Road Famous Teochew Chendul, nasi kandar at Line Clear in Penang Road. Minimum 3 nights. The Cameron Highlands (3 hours by bus from Ipoh) are cool, green, and smelling of soil and tea — 2 nights. Kuala Lumpur needs 2 nights for Brickfields, Chinatown, and the Petronas Towers, which are more impressive from the KLCC park below than from the observation deck.
Minimum: 7 days. Comfortable: 10 days.
