Rules in force · 5Drug trafficking can carry the death penalty in Singapore…
  • Southeast Asia ↗Drug trafficking can carry the death penalty in Singapore, Malaysia, Indonesia, Vietnam, Laos, Thailand, Brunei and Myanmar; never carry a bag or parcel for anyone.
  • Southeast Asia ↗Carry a passport valid for at least six months from entry with two blank pages; airlines refuse boarding on less.
  • Cambodia ↗Apply for the e-visa only on the official government portal; lookalike sites charge extra. Some nationalities can also get a visa on arrival.
  • Cambodia ↗Angkor Wat and other active temples enforce a dress code: shoulders and knees covered, or you are turned away at the gate.
  • Cambodia ↗US dollars are used for most tourist prices; carry clean, undamaged small notes and some riel for change under one dollar.

The Mekong Lowlands and Central Plains is the flat middle of Cambodia: the capital, the Mekong river towns and the rice plains that feed them. Most travellers cross it on the Phnom Penh–Siem Reap road or the Phnom Penh–Kratie river road. Treat it as a 2–4 night add-on to Phnom Penh, not a destination in itself, unless you want slow river towns and Khmer rural life at a low cost.

  • Do not plan to see Phnom Penh, Kampong Cham and Kampong Thom in two days: each leg eats half a day.
  • Rural roads can flood in the wet season (roughly June–October); buses slow down or reroute.
  • Check your own government's travel advice and the current land-border status before any overland leg.

Phnom Penh and the plains
Hot season March–May pushes past 35 °C (95 °F); the wet season June–October brings short heavy afternoon downpours and flooded side roads. November–February is the comfortable window.

The region is low and flat, so it holds heat and water. If you only have one dry-season window, aim for December–January.
