Ko Chang,Thailand.

Ko Chang has no airport or bridge, so all arrivals require a ferry crossing. The fastest route from Bangkok is to fly Bangkok Airways from Suvarnabhumi Airport (BKK) to Trat Airport (TDX) — roughly 3 daily flights, ~45-minute flight — then take a shared minivan or private transfer the ~20 km to Ao Thammachat pier (transfers approximately 550 THB one-way, 990 THB return; book ahead as airport taxis often won't do the ferry run). Ferries depart from Ao Thammachat pier to Ko Chang's Ao Sapparot pier daily from 06:00–19:30 year-round; the crossing takes about 30 minutes. Budget travellers can take a direct bus from Bangkok's Ekkamai Bus Station to the mainland pier — a roughly 5–6 hour journey that often includes the ferry fare. Note: Trat Ferry (formerly Centrepoint Ferry) has been suspended since July 2024 and is unlikely to resume; use the Ao Thammachat departure instead.

A single main road runs down Ko Chang's west coast connecting all the major beaches, but distances are significant and the terrain is steep and winding. Songthaews (shared pickup trucks) are the primary public transport — fares run approximately 40–80 THB depending on distance; note that drivers may wait until seats are filled, particularly in low season. Motorbike rental is the most flexible option at 150–300 THB per day; helmets are strongly advised given the island's winding, hilly roads (motorbike accident rates in Ko Chang are among the highest in Thailand). Cars can be brought over on the ferry for an extra fee of around 120–150 THB on top of the ferry ticket. The eastern side of the island has very limited public transport, so a rented scooter is essential for exploring fishing villages and waterfalls there. Most island-hopping and diving/snorkelling boats depart from Bang Bao Pier in the south.

Ko Chang has two distinct seasons. The dry season (November–April) is peak time: skies are clear, seas are calm, and temperatures are a comfortable 27–30 °C. December–February is widely considered the sweet spot — sunshine stretches to 9 hours a day, dive visibility can reach 20–30 m around the HTMS Chang wreck, and snorkelling trips to Koh Rang National Marine Park run daily. February is statistically the quietest dry-season month, a smart pick if you want sun without the December–January holiday rush. March and April remain warm and largely dry but temperatures climb toward 33–35 °C. The monsoon (May–October) brings heavy rain — July and August are the wettest months — and most boat trips face cancellation risk; however, accommodation discounts and lush green landscapes attract budget-conscious visitors. November is a transitional month: rains taper off sharply and Loy Krathong festival (full moon, usually November) creates a magical atmosphere along the island's beaches and waterways. Avoid Thai public holidays if possible, as Ko Chang becomes a busy getaway for domestic tourists.
