Rain days are the days with at least 1 mm of rain, as a weather station counts them.

Weather read at Long Beach (Phra Ae): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. It is flagged rather than scored down, and crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

How busy it gets

Busiest from November to March; quietest from May to October.

Getting there

Fly into Krabi (KBV), then drive. The flights under Where to book are to Krabi.

The drive from each airport is the road's, from openrouteservice.org by HeiGIT: typical, not a schedule.

How far Ko Lanta is, and what it costs, depends on where you set off from — the months above do not.

Before you go

Type A and B and C and F plugs at 220 V. Drives on the left. The currency is the Baht. UK Foreign Office: avoid all but essential travel to parts. Everything for Thailand: cost of living, languages, emergency numbers and health.

Being there

On arrival

  • Paying — Cards work in malls, hotels and tourist restaurants; carry 20 and 100 baht notes for street food, markets and taxis. Many small sellers use PromptPay QR, which mostly needs a Thai bank app.
  • UPI, for visitors from India — Not accepted for paying here; bring a card that works abroad.
  • Tipping — Not expected; Thais round taxi fares to an easy number and sometimes leave small change in restaurants. Do not tip on top of a service charge.

Getting around Ko Lanta

  • Apps — Rides: Bolt, Grab. Maps: Google Maps, Apple Maps. Messages: LINE, WhatsApp.

The main roads on the island are well paved. However the road just north of Mu Ko National Park is still unpaved dirt. More on Wikivoyage

Ko Lanta in pictures

What Ko Lanta is like

Ko Lanta (เกาะลันตา) is an archipelago off the Andaman Coast of Southern Thailand. Like many other destinations in Krabi Province, it is known for its diving and long white beaches. More on Wikivoyage

Worth seeing
Khao Mai Kaew Caves (ถ้ำเขาไม้แก้ว) (Just off the lower of two cross-island roads, down a narrow 1.5 km dirt path through the rubber plantations). More on Wikivoyage
Worth doing
There are no scuba diving sites on the island itself, all require a boat trip. However Lanta is the closest island to the famous Hin Daeng, Hin Muang, and Ko Haa sites, so it is very popular with divers. More on Wikivoyage
Getting in
The nearest airports are Krabi, Trang and Phuket. Krabi and Trang have direct road and boat connections to Ko Lanta, and are the best options if you're only visiting Ko Lanta. More on Wikivoyage
