Pros & cons of Thailand buses
Honest synthesis of French and English-speaking traveler feedback.
Over 70,000 km of highways, all tourist destinations served, including islands via combo tickets. No major destination is unreachable by bus.
€1-3/hour of travel depending on class. The overnight VIP Bangkok → Chiang Mai at €20 is unbeatable (saves a hotel night).
Reclining 3-per-row seats, meals included, blanket, sometimes individual screens and USB ports. Travelers compare to European overnight train comfort.
For islands (Koh Samui, Koh Phangan, Koh Tao, Phi Phi, Koh Lipe), one ticket = bus + ferry, connection guaranteed by operator if late.
The #1 point cited in reviews. Bring sweater + scarf, especially overnight. It's cultural — Thais love AC blasted.
30min-1h delay happens ~1 in 5 trips (Bangkok traffic, weather). For ferry combos, the connection is protected by the operator.
Notoriously sporty driving, cramped with luggage, uncomfortable. OK for short tourist routes (Krabi → Ao Nang, Chiang Mai → Pai), avoid beyond 3-4h.
Risk almost exclusive to Khao San Road buses in Bangkok, or shady street agencies. Keep valuables in cabin. Booking via 12go.asia (verified operators), risk is negligible.
Bus vs Train: travelers' verdict
On forums (Routard, Reddit, Voyage Forum), the bus vs train debate for long overnight routes (typically Bangkok → Chiang Mai) keeps coming up. Here's the synthesis:
📊 Tourdumondiste survey (1,017 travelers): 77% used the bus in Thailand, vs 38% the train.
🚆 Train pros: Considered safer by the Routard community. Spacious 2nd-class sleeper bunks, saves a hotel night, "Orient Express" feel. But: slower (13-15h vs 9-11h VIP bus) and requires advance booking.
🚌 VIP bus pros: Faster, more frequent, similar or lower price, combo tickets to islands. VIP comfort very decent per travelers (reclining 3-per-row seats).
🏆 Verdict: For Bangkok → Chiang Mai and other long inter-city routes, overnight train wins on comfort & safety. For islands, tourist sites or the south, VIP bus remains unbeatable in practicality and cost.
Safety — the real numbers
Several travelers worry (rightly) about road safety in Thailand. The facts:
- Thai roads: statistically among the most accident-prone in the world (WHO), but scooters and motorbikes account for 75% of accidents — not buses.
- Long-distance buses: very few serious accidents reported. On thousands of daily buses, serious incidents are rare.
- Risky operators: private minivans with sporty driving, very low-end buses via Khao San Road street agencies, and some trips with overworked drivers (consecutive long overnight routes).
- Safe operators: majors (Transport Co., Nakhonchai Air, Sombat, Greenbus, Lomprayah) follow strict protocols. Nakhonchai Air even runs random drug/alcohol tests on its drivers.
- Cargo theft: reported almost exclusively on Khao San tourist buses → islands. Booking via 12go.asia with verified operators, risk becomes negligible. Keep valuables in cabin always.
💡 Golden rule: if the driver looks tired or under influence, or the bus is visibly in poor condition, don't take the risk — take the next bus. It rarely happens with major operators booked online.
8 tips for great travel — from 50,000+ reviews
- Pick an operator rated 4.3+/5 — on 12go.asia, filter by rating. Nakhonchai Air, Lomprayah, Sombat, Greenbus are safe bets.
- Avoid Khao San Road for booking — street agencies charge commission, sell low-end, and concentrate negative reviews (theft, delays, beat-up buses).
- Bring sweater + scarf — AC is really very cold, especially overnight. #1 mention in all reviews.
- Keep valuables in cabin — passport, cash, electronics, never in cargo hold. Lock on suitcase if possible.
- Pick VIP on trips > 6h — the price difference (€5-10) is well worth it on long routes. 3-per-row seats, meals, blanket.
- Book 48-72h ahead in high season — Dec-Feb, Songkran (April), Full Moon at Koh Phangan: VIP sells out fast. Otherwise you'll be stuck on Express.
- Foam earplugs — passengers often phone all night. Small expense, big sleep impact.
- Check recent reviews — on 12go.asia, reviews are dated. Prioritize the last 6 months (operators evolve quickly).
