Getting there & entry

HKT (Phuket International) — 1-stop (no US nonstop) (No US nonstop to Phuket. ~20–26h with 1–2 stops via an Asian or Gulf hub — LAX shortest (~20–22h) via Tokyo/Seoul/Taipei/Hong Kong; often connect through Bangkok (BKK) then a 1h20 domestic hop to HKT. East Coast 24h+.)

Transfer: ~45 min–1h to the west-coast beaches (Patong/Kata/Kamala) by airport taxi/minibus or private transfer · ~$25–50 per car (metered taxis ~800–1,000 THB)

Entry (US): 60-day visa exemption for US tourists (2024 rule); passport 6-mo validity. Thailand Digital Arrival Card (TDAC) required online within 3 days of arrival; proof of ~20,000 THB funds pp technically required. No vaccines required (yellow-fever cert only if arriving from an endemic country); Hep A/typhoid recommended.

Excellent on-the-ground value (pool villas, food, massage); the 20–26h long-haul airfare is the main cost.

Access & safety

hilly island; beaches sit down winding roads, so you'll use taxis/private drivers or rent a car/scooter (metered taxis are scarce — agree fares first) · stroller/wheelchair: resorts OK; beaches are soft sand with steep access roads and patchy sidewalks

tap water: not safe — bottled/filtered only · altitude risk: none · uv heat: high tropical UV and heat (up to ~95°F in April) · water safety: SW-monsoon (May–Oct) rip currents on the west coast are deadly — obey red flags; jellyfish seasonally; dengue present
