Thailand Islands Guide 2026: Phuket, Phi Phi, Krabi, Koh Samui & Island Hopping

🏖️ Phuket: The Island Base Camp

• Phuket is the logistics hub: biggest airport, most flight connections, and ferries to every Andaman island
• Stay Kata or Karon for quieter beaches; Patong is nightlife central — choose your vibe before booking
• Old Phuket Town pairs Sino-Portuguese shophouses with a café scene — perfect for a rainy afternoon
• Grab works on Phuket; songthaews (shared trucks) run fixed routes for 30-50 baht if you have time to spare

⛵ Phi Phi & the Classic Day Trips

• Ferries to Phi Phi leave Rassada Pier several times daily; the 45-minute crossing is the shortest sea leg
• Maya Bay reopens seasonally with visitor caps — book the early slot, swim before the crowds land
• Bamboo Island and Mosquito Island have the whitest sand in the archipelago — quieter than Maya Bay
• Overnight on Phi Phi if you can — days belong to tours, but sunrise at the viewpoint is yours

⛰️ Krabi: Railay, Ao Nang & Lanta

• Railay Beach is cut off from roads — longtail boats from Ao Nang (15 min, ~200 baht) are the only way in
• Railay East climbs limestone cliffs for sport routes of every grade; West Railay is for sunset sand
• The Four Islands tour (Phra Nang, Tub, Chicken, Poda) runs half-day from Ao Nang for 500-800 baht
• Koh Lanta is the low-key escape: long quiet beaches, no beach clubs, and the Old Town on stilts

🗺️ Koh Samui & the Gulf Islands

• Samui has its own international airport — the Gulf side works even in Andaman monsoon months
• Ang Thong Marine Park is the must-do: 42 limestone islands with a green lagoon hike and kayak coves
• Koh Phangan is more than Full Moon Party: west-coast beaches and viewpoints are genuinely peaceful
• Lipa Noi on Samui has the shallowest sunset water — bring kids here, not Chaweng

❤️ Island Hopping: Boats, Routes & Timing

• Lomprayah and Songserm run the Gulf ferry network; book combo bus+ferry tickets from Bangkok online
• Andaman longtail charters are negotiable: half-day around Ao Nang runs 1500-2500 baht per boat
• Peak season splits: Andaman Nov-Apr, Gulf Jan-Sep — when one coast rains, the other shines
• National park fees (400-600 baht) are collected in cash at most islands — keep small notes in a dry bag

📱 Safety, Money & Connectivity

• Red flags on beaches mean currents, not closings — Andaman undertows are real, swim inside flags
• ATMs charge 220 baht per withdrawal island-wide — take out larger amounts, fewer times
• Travel insurance that covers scooter accidents and boat transfers is essential on island routes
• One Thailand eSIM keeps navigation, Grab and ferry bookings alive across every island and pier

💡 Quick Tips

• Book island ferries a day ahead in high season — walk-up tickets sell out by 10am
• Reef-safe sunscreen is legally required in marine parks — the regular kind damages coral
• Negotiate longtail and taxi prices before boarding; fixed-price booths beat street touts
• Scooter rental is cheap but real: drive left, helmet on, and check the tire tread before paying
• Cash still rules at beach shacks and small piers — cards work in resorts, not at the mango sticky rice cart
• Check tide tables for viewpoint hikes and reef swims — low tide changes everything
• One eSIM across Phuket, Krabi and Samui beats buying three local SIMs at three piers

⚡ Pro Tips

• Fly into Phuket and out of Krabi (or reverse) — open-jaw saves a full day of backtracking down the coast
• Private longtail for 2-3 people often costs less per head than a group speedboat tour — and you set the timing
• Monsoon secret: when the Andaman coast closes, shift to the Gulf — Samui, Phangan and Tao sail all summer

📋 Summary

Thailand's islands reward planning: base in Phuket or Krabi for the Andaman, Samui for the Gulf, hop early before the tour boats, and let one eSIM hold the whole route together.
