The perfect 7-day Koh Samui itinerary for groups

Seven days. One island. A group of friends ready to push their limits, explore every corner, and make memories that'll get retold at every dinner party for years. Here's exactly how to spend a week on Koh Samui — no filler, no tourist traps, just the good stuff.

Koh Samui is made for group travel. The villas are built for it, the island is big enough to keep surprising you, and the mix of adrenaline, nature, nightlife, and culture means everyone gets their moment. Whether your crew is into cliff jumping, Muay Thai, night markets, or just a long table of fresh seafood with cold Changs — Koh Samui delivers.

This itinerary is built around adventure and staying active, while leaving room to breathe. We've split the island into zones so you're not wasting half your day in a songthaew. Let's go.

Day 1 - Arrive, settle in, get your bearings

Area: Bophut / Fisherman's Village

Afternoon - Check into your villa, claim your rooms, and do the only thing that matters first — jump in the pool. Give yourselves a couple of hours to decompress from the journey.

Evening - Head to Fisherman's Village in Bophut for your first evening. Stroll the charming old street, grab drinks at one of the waterfront bars, then sit down for a seafood dinner at one of the local restaurants along the strip. Order the whole fish and the pad thai. Order everything, actually.

Night - If the group has energy, the Friday Walking Street market in Bophut is one of the island's best — local food stalls, live music, street performers, and the kind of chaos that only happens in Thailand. Check if it's running during your visit.

Siam-CS tip - Staying with us? Our team can arrange a chilled welcome dinner at your villa — think fresh local dishes served poolside, letting you settle in before the adventure begins.

Day 2 - Muay Thai morning + Chaweng beach day

Area: Chaweng

Morning - Start day two with a Muay Thai session. Koh Samui has several excellent gyms offering group training — don't worry, you won't be sparring on day one. The trainers are used to beginners and the morning sessions are as fun as they are punishing. Expect to be sore in muscles you forgot existed.

Midday - Recover at Chaweng Beach — the island's longest and most famous stretch of sand. Rent sun loungers, grab lunch from one of the beach shacks, and spend a few hours in the water. The sea here is clear and warm year-round.

Evening - Chaweng comes alive at night. Bar-hop along the main strip, catch a Muay Thai fight at Chaweng Boxing Stadium (a genuine experience — not a tourist show), then finish at one of the beach clubs for a nightcap.

Siam-CS tip - We can book a private Muay Thai session with a trainer who comes directly to your villa — ideal for groups who want to learn together in a more relaxed setting before hitting a gym.

Day 3 - Private boat day — island hopping

Area: Ang Thong Marine Park & surrounding islands

Full day - This is the day your group will talk about most. Charter a private speedboat and head out to Ang Thong Marine Park — a UNESCO-protected archipelago of 42 uninhabited islands about 30km northwest of Koh Samui. Think towering limestone cliffs, hidden lagoons, snorkelling in crystal water, and a complete absence of crowds (because you're not on a tour bus in the sea).

Highlights - Kayak into the emerald lake at Ko Mae Ko, snorkel off Ko Sam Sao, cliff-jump from Ko Wao, and eat a freshly prepared lunch on the boat deck between islands. Build in time to anchor in a quiet bay and just swim.

Siam-CS tip - We organise private boat excursions for our guests — full day, your itinerary, your pace. No sharing with strangers, no rush. Just tell us your group size and we'll handle the rest.

Day 4 - Jungle interior + waterfalls + ATV

Area: Na Muang / central highlands

Morning - Rent ATVs and head into the island's jungle interior. Koh Samui's highlands are dramatically different from the coastline — dense forest, steep ridges, and sweeping views down to both coasts. Most ATV operators run guided group tours that take you along jungle trails you'd never find on a scooter.

Midday - Stop at Na Muang Waterfall — the island's best waterfall, set in a lush valley. Swim in the natural pool at the base. It's refreshing in a way that only cold natural water in 35-degree heat can be.

Afternoon - Head back to the villa for a late swim. Tonight is a quieter one — dinner at a local restaurant in the Nathon or Taling Ngam area on the west coast, known for its stunning sunsets and far fewer crowds than Chaweng.

Day 5 - Scuba diving or snorkelling + cooking class

Area: Choeng Mon / east coast

Morning - Take a morning dive or snorkel trip off Koh Samui's east coast. The waters around Koh Tan and Koh Matsum are excellent for beginners and certified divers alike — coral gardens, sergeant major fish, and the occasional reef shark if you're lucky. Several operators offer day trips from the main piers.

Afternoon - Back on land, spend the afternoon in a Thai cooking class. Learning to make a proper green curry, pad kra pao, and mango sticky rice together is one of those group activities that sounds low-key but ends up being one of the best afternoons of the trip. Plus, you eat everything you cook.

Evening - Choeng Mon beach at sunset is one of the most underrated spots on the island. Quieter than Chaweng, lined with casuarina trees, and genuinely beautiful. Grab drinks here before heading back.

Siam-CS tip - We can arrange a private cooking class at your villa — a local Thai chef comes to you, teaches the group, and leaves you with a feast. No minibus, no shared table with strangers.

Day 6 - Big Buddha, temples + Lamai beach night

Area: Plai Laem / Lamai

Morning - Visit Wat Plai Laem — a spectacular temple complex on a lake featuring an 18-armed goddess statue and golden Buddha. Far less visited than the famous Big Buddha nearby, and genuinely breathtaking in the early morning light. Combine both in the same visit — they're a five-minute walk apart.

Afternoon - Drive south to Lamai Beach for the afternoon. Lamai is Koh Samui's second-largest beach — slightly rawer and more local-feeling than Chaweng. Rent jet skis, try parasailing, or just swim and people-watch from a beach bar.

Night - Lamai has a lively night scene centred around a compact strip of bars and open-air clubs. This is your last big night out — make the most of it.

Day 7 - Slow morning, private chef lunch, farewell swim

Area: Your villa

Morning - Nobody wants to do anything on the last day. And that's fine. Sleep in, swim, sit by the pool, and quietly agree this was one of the best trips you've done. Maybe a short walk or a final scooter ride to a viewpoint, but nothing scheduled.

Midday - Go out on a high — have a private chef come to the villa and cook a proper send-off lunch. Fresh seafood, Thai classics, maybe a whole grilled fish. Eat slowly, drink cold drinks, and sit around the table longer than you need to. This is what Koh Samui is actually about.

Afternoon - One last swim. Then pack, check out, and make your way to the airport with that particular kind of heavy-hearted happiness that only a really good trip leaves behind.

Siam-CS tip - Our private chef service is one of the most loved things we offer. Just tell us dietary preferences and how many people — we handle everything from ingredients to clean-up.

A few practical tips before you go

Getting around - Rent scooters or hire a driver for the week. Songthaews (shared pickup trucks) are cheap but slow. For a group, a rented van or private driver makes sense.

Best time to visit - December to April is peak season — dry, sunny, and perfect. July to August is also great. Avoid October and November if possible (wettest months).

Stay in a villa - For groups, a private villa beats a hotel every time. Shared pool, shared space, no corridors — you're together from the moment you wake up.

Book activities early - Private boat charters and Ang Thong permits fill up fast in high season. Sort these in the first 24 hours, not the day before.

"The groups who have the best trips are the ones who balance structure with spontaneity — a few big anchors in the week, and space for the island to surprise them." — Siam-CS Management, Koh Samui since 2013
