Five days is the sweet spot for Koh Samui. Long enough to reach two neighbouring islands without any of them feeling rushed — Ang Thong Marine Park on one day, Koh Tao for diving or snorkelling on another — and still have a proper final morning on the beach rather than packing at noon.
Two advance bookings required; everything else you can sort on arrival.
The short version
- Day 1: Arrive, Chaweng Beach, settle in
- Day 2: Island loop — Big Buddha, Bophut, Na Muang Waterfalls, interior viewpoint
- Day 3: Ang Thong Marine Park (full day — book before you land)
- Day 4: Koh Tao day trip — Lomprayah ferry, snorkelling, Koh Nang Yuan viewpoint
- Day 5: Silver Beach and Lamai, cooking class or spa afternoon, Chaweng night market
The two non-negotiable advance bookings: Ang Thong (sells out weeks ahead in high season) and the Lomprayah return ferry to Koh Tao. Book both before you fly, or at the absolute latest the night you land.
Before you arrive
Read the best time to visit guide before buying flights — Koh Samui’s wet season runs October to December, the opposite timing from Phuket’s. It matters for Days 3 and 4 especially.
Sort accommodation before landing. The where-to-stay guide covers the island by area and budget. For getting around once you’re on Samui — scooters, songthaews, private transfers — the getting-around guide has the full picture.
Only have four days? The 4-day itinerary covers Ang Thong, the island loop, and a Koh Phangan option. This guide adds Koh Tao and a relaxed final day in place of the rushed departure.
Day 1: Arrive + Chaweng
Afternoon: Samui Airport is small — you’re through immigration in 20–30 minutes. A private taxi to Chaweng runs ฿300–400; a shared songthaew is ฿100–150 but slower and won’t take luggage easily. Check in, drop your bags.
Head to Chaweng Beach. The northern end (Chaweng Noi) is quieter than the central stretch — walk 10 minutes north if the main beach is crowded with sun loungers and hawkers. The beach faces east so there’s no sunset from the sand, but late afternoon light on the Gulf is worth the stroll.
Evening: One block off the main beach road, the lake road parallel to the strip has a row of Thai restaurants that don’t cater exclusively to tour groups. Start there. See the food guide for specifics.
Note: If you arrived late or tired, do beach and dinner only. Day 1 is meant to be recovery, not sightseeing.
Day 2: Island Loop — North Coast and Interior
A full day of movement. Best done by hired scooter (฿200–300/day from almost any guesthouse) or by chartering a songthaew for the day (฿1,000–1,500 for the vehicle, negotiate before you get in). Route: Chaweng → Big Buddha → Bophut → Na Muang Waterfalls → interior viewpoint → back to base.
Big Buddha (Wat Phra Yai) — 9:00am
Start before the coach tours. The golden 12-metre Buddha sits on Ko Fan, a small island off the northeast coast connected by a short causeway. Naga-flanked stairs lead up to the statue. Shoulders and knees must be covered; sarongs are available at the gate. Entry is free. Allow 45 minutes.
While you’re in the area: Wat Plai Laem — a large multi-armed Guanyin statue over a lotus pond, five minutes east along the coast road — is mostly skipped by tour groups and worth the short detour.
Fisherman’s Village, Bophut — 10:30am
Ten minutes west along the north coast. Bophut’s old Chinese shophouse street is the one stretch on the island that still looks like somewhere people live. Have coffee, a late breakfast, or walk the waterfront. If it’s a Friday evening later in your trip, put this area back on your list — the Friday Walking Street market (from ~5pm) is the island’s best. Full detail in the Bophut guide.
Na Muang Waterfalls — 12:30pm
Head south through the interior on Route 4169. Na Muang 1 is the main falls — a broad 20-metre cascade into a natural swimming pool. Worth going in if you want to; the water is cool. Na Muang 2 is a 30-minute uphill walk further in and is quieter. No entry fee at either. Pack food or eat from the roadside stalls at the track entrance; there’s no proper restaurant up there.
Interior Viewpoint — 2:30pm
Several viewpoints on the central ridge give clear lines over both coasts simultaneously. The main one sits on Route 4169 between Chaweng and the interior — look for a concrete platform, a drinks vendor, and scooters parked at the edge. Good on a clear day; not worth stopping for in overcast weather.
Evening: Back at base by 4–5pm. Friday nights in Bophut — the walking market is the right call for dinner.
Day 3: Ang Thong Marine Park (Full Day)
Early alarm. Tours depart from Nathon or Maenam pier between 8:00 and 8:30am. This must be booked before Day 3 — ideally before you land, certainly not the same morning.
Standard big-boat group tours: ฿1,200–1,800 per person, including lunch, snorkel gear, and park entry. Speedboat tours cover more of the 42-island archipelago and run faster: ฿2,000–2,800. The park entrance fee (฿300 for foreign adults, ฿150 for children) is usually included — confirm before paying.
A typical day covers: snorkelling on the outer reef, the 30–40 minute hike to the hilltop viewpoint on Koh Wua Talap (the panoramic shot you’ve seen in every photo of Ang Thong), sea kayaking into the emerald lagoon on Koh Mae Ko, and lunch on the main island. Take proper shoes rather than sandals — the viewpoint hike is steep and rocky.
Tours return to Samui by 5pm. You’ll be sun-tired and fed. A quiet dinner close to accommodation is the right call.
Full details, booking tips, and seasonal closure information (Ang Thong closes approximately 1 November–15 December due to sea conditions) in the Ang Thong Marine Park guide.
Day 4: Koh Tao — Snorkelling and Koh Nang Yuan
Koh Tao sits roughly 70km north-west of Samui — about two hours by Lomprayah’s high-speed catamaran. Most people go for the diving (it’s among the cheapest places in Southeast Asia to learn, with proper conditions). The snorkelling is excellent and you don’t need a dive ticket to enjoy it.
Getting there: Lomprayah departs Maenam Pier around 8:00am and Nathon Pier around 8:30am. Fare: ฿450–600 one way, so ฿900–1,200 return. Buy return tickets when you buy the outward leg — the last departure from Koh Tao is around 16:30 and it sells out. Book on 12Go or Lomprayah’s website; do it before you fly in peak season (December–April).
On the island: You land at Mae Haad Pier on Koh Tao’s west coast. Sairee Beach is a short walk north — the island’s longest beach and the strip where all the dive schools, restaurants, and bars are concentrated.
Where to spend your time:
-
Koh Nang Yuan — Koh Tao’s postcard shot: three rocky hills connected by white sandbars, clear shallow water between them. A longtail from Mae Haad takes 15 minutes (฿200 return). Entry to the island is ฿250 per person; snorkel gear is a separate rental at ฿100–150. The viewpoint hike is 20 minutes and delivers one of the best views in the Gulf. Go here first — it gets crowded by midday.
-
Shark Bay — On Koh Tao’s southern tip, blacktip reef sharks rest in the sandy shallows year-round. Completely harmless. Reachable by scooter hire from the pier (฿150–200/day) or longtail. Worth the trip purely for the novelty.
-
Organised snorkel tour — Half-day tours running from Sairee typically cover Koh Nang Yuan, Shark Bay, Mango Bay, and Hin Wong Bay for around ฿500–700 per person including gear. Good if you want to see multiple sites without navigating longtail logistics yourself.
If you want to dive: Fun dives run ฿800–1,000 per dive at Sairee’s schools. A day trip gives you time for one, maybe two dives. For a PADI Open Water course (฿9,900 and up), you need at least two nights on the island. Full logistics in the Koh Tao guide.
Return: Leave Koh Tao by 16:30 at the latest. Back on Samui by 7pm.
Day 5: South Coast + Cooking Class or Spa
The final day is deliberately unhurried. No early alarms, no boats to catch.
Morning: Silver Beach and Lamai
Head south out of Chaweng along the coast road. Silver Beach (also signposted as Crystal Bay or Thongtakian) comes first, about 10 minutes down — a 250-metre cove sitting between Chaweng and Lamai. The water here is the clearest on the east coast, and the rock formations at each end of the cove make it Samui’s best onshore snorkelling without getting on a boat. Get there before 10am; it fills fast. The access road is steep, which is why it’s never as crowded as Chaweng. Full write-up in the best beaches guide.
Carry on south to Lamai, another 10 minutes along the same road. Lamai’s beach is quieter than Chaweng with good swimming. The southern end near Hin Ta and Hin Yai (the grandmother and grandfather rocks) is worth walking to — distinctive granite formations right at the waterline, and the beach narrows here.
Afternoon: cooking class or spa
Pick one.
Cooking class: Samui has several good schools. Group classes (4–6 dishes, 3 hours) start from ฿2,500 per person and most include a market visit beforehand, which is the more interesting hour. Jungle Kitchen runs sessions from Fisherman’s Village with shuttle service (around ฿3,900/person). Infusion Cooking Classes offers private sessions at ฿5,990 for two — worth it if you prefer not to share bench space with a group of twelve.
Spa: Traditional Thai massage is ฿300–500 per hour in a local shop and available on virtually every street in Chaweng and Lamai. Resort spas charge ฿2,000–4,000 for a 60-minute treatment and are meaningfully better — quieter, better-trained therapists, no plastic-chair waiting area. Pick based on budget.
Evening: Chaweng night market
End the trip properly. The Chaweng night market runs most evenings along the central strip — grilled satay, pad thai, fresh seafood, mango sticky rice, tropical fruit, the standard range of tourist gear. The stalls near the lake road end of the market are better value than those on the main beach road. Go for the food; don’t bother with the souvenirs unless something catches your eye.
Day-by-Day Cost Summary (per person, excluding accommodation)
| Day | Main activity | Estimated cost |
|---|---|---|
| 1 | Airport taxi + beach + dinner | ฿400–600 |
| 2 | Scooter hire + fuel + food | ฿400–700 |
| 3 | Ang Thong Marine Park (big boat) | ฿1,200–1,800 |
| 4 | Koh Tao return ferry + snorkelling + food | ฿1,200–1,800 |
| 5 | Scooter + activity (class or spa) + dinner | ฿2,800–4,500 |
Mid-range five-day activity spend: ฿6,000–9,400 per person (roughly NZ$270–425 at current rates). Budget travellers using songthaews over scooters and skipping the cooking class can get the activity spend to ฿4,000–5,000. The two expensive days are Ang Thong and Koh Tao — both are worth it.
Practical Notes
Transport: Scooters are the right call for Days 2 and 5. Songthaews (฿50–100 per person per leg) connect the main beaches and work fine for getting between Chaweng and Lamai. The getting-around guide covers all options.
Advance bookings: Two are non-negotiable — the Ang Thong tour (Day 3) and the Lomprayah return ferry to Koh Tao (Day 4). Everything else can wait until you land.
Monsoon timing: Ang Thong closes approximately 1 November–15 December. If your trip falls in that window, swap Day 3 for Koh Tao and Day 4 for a Koh Phangan day trip — the order still works logistically. Check the best-time guide before booking flights.
Base camp: Chaweng is the most convenient base for this itinerary — close to the airport and central to the east coast beaches. The ferry piers are a drive: allow 20–30 minutes to Maenam on the north coast and 40–55 minutes to Nathon on the west. If quieter nights matter to you, Bophut works well for Days 1–3 and cuts the run to Maenam to a few minutes. Browse the full hotel list at /hotels/.
FAQ
Is five days enough time for Koh Samui?
Five days covers the main sights comfortably — the island loop, Ang Thong Marine Park, Koh Tao, the south coast beaches, and the Chaweng market. The one thing you won’t have time for is a proper Koh Tao dive course, which needs at least two nights on the island. The Full Moon Party on Koh Phangan runs to a fixed calendar and may not fall within your dates.
Do I need to book Ang Thong Marine Park in advance?
Yes. Tours regularly sell out, especially December through April. Book through any reputable tour agency before you land — your hotel can do it on arrival, but don’t leave it to the morning of Day 3.
Can you do Koh Tao as a day trip from Koh Samui?
Yes, and this itinerary does exactly that. The Lomprayah departs Samui around 8am and the last return from Koh Tao is around 16:30, giving you roughly six hours on the island. That’s enough for snorkelling and the Koh Nang Yuan viewpoint. It’s not enough for a full dive course or serious exploration — if diving is the main reason you’re going, add a night.
What’s the best area to stay for a five-day trip?
Chaweng for convenience — closest to the airport and central to the east coast beaches. Budget 20–30 minutes to reach Maenam pier for Day 4’s Koh Tao ferry, and 40–55 minutes to Nathon. If you prefer quieter surroundings, Bophut on the north coast also works and sits far closer to the north-coast ferry piers. Full breakdown in the where-to-stay guide.
How much does five days in Koh Samui cost?
Activity and food spend (excluding accommodation): ฿6,000–9,400 per person mid-range. Budget travellers using local transport and skipping the cooking class can get this to ฿4,000–5,000. Accommodation varies from ฿400/night in a guesthouse to ฿6,000+/night at a private pool villa. The two biggest activity costs are Ang Thong (฿1,200–2,800) and the Koh Tao day (฿1,200–1,800 return transport plus snorkelling).
