Bottom line: Koh Samui and Koh Phangan offer resort comfort with island prices—€40-100/night boutique hotels, €3 pad thai, €8 cocktails by the beach. Ang Thong Marine Park day trip (€45/person via Klook) is the highlight—42 islands with hidden lagoons and snorkeling. Skip the Full Moon Party chaos; the island has quieter beaches if you know where to look.
Koh Samui is Thailand’s most developed resort island—international airports, luxury hotels, and spa retreats. Koh Phangan sits 30 minutes north, infamous for Full Moon Party but equally rewarding for its quieter beaches and jungle waterfalls. Combined, they make a perfect Thai island week.
Koh Samui: The Resort Island
Best Beaches
Chaweng Beach (east coast): The longest and most popular. Calm water, palm trees, lifeguards. Loud at night. Best for: first-timers.
Lamai Beach (east coast): Samui’s second beach town, more local, half the crowds. Best for: couples and families.
Bophut Beach (north): Fisherman’s Village has the best restaurants on the island and a Friday night walking street. Best for: good food and boutique shopping.
Maenam Beach (north): Quiet, local, cheaper than Chaweng. Good for: peace seekers.
Ang Thong Marine Park
The highlight of any Samui trip—42 limestone islands jutting from the sea, with hidden lagoons, coral reefs, and viewpoints.
Day trip options:
- Speedboat tour: €50-65/person (book via Klook for €45), includes snorkeling, kayak, viewpoint hike
- Overnight camping: €100/person, sleep on the beach in Wua Talap island
What to see: Emerald Lake (lagoon in the middle of an island), viewpoints, snorkeling with sea turtles (yes, really).
Practical Info
- Getting around: Songthaew (shared pickup truck) €1-2/ride anywhere. Rent a scooter (€10-15/day) if confident on Thai roads.
- Airport: Bangkok Airways exclusive terminal, flights are pricey (~$100 Bangkok-Samui). Ferries from the mainland are cheaper but take 6+ hours.
- SIM card: Get AIS or TrueMove SIM at airport (€8 for 15GB). Use Airalo for eSIM.
Koh Phangan: Beyond the Full Moon
Koh Phangan has a split personality. The southern tip has Full Moon Party—60,000 people, full moon, chaos. The rest of the island has jungle waterfalls, hidden temples, and quiet coves.
Alternative Beach Guide
Haad Salad (northwest): Quiet fishing village beach, good snorkeling, fresh seafood restaurants. Best for: actual relaxation.
Thong Nai Pan Yai (northeast): Tranquil bay, no party, some of the island’s best luxury bungalows. Best for: couples and honeymooners.
Haad Rin (south): Full Moon Party beach. If you’re here for the party, this is it. If you’re not, stay 2km away.
Natural Wonders
Namtok Than Sadet (Than Sadet Waterfall): The island’s biggest waterfall, a 3-hour hike through jungle. Free entry.
Khao Ra (Mountain Summit): The island’s highest peak (627m). Half-day hike. Viewpoint at the top is spectacular at sunrise—but you have to start at 5am.
Slip ‘n Fly: For the Full Moon Party crowd. Giant inflatable slip ‘n slide into a pool. €30. It’s exactly as fun as it sounds.
Getting Between Samui and Phangan
Ferry: Lomprayah catamaran, 30 min, €8/person. Runs every hour. Speedboat: €15/person, 15 min. bumpier but faster.
Book via Klook for €7 vs. buying at the pier.
