Koh Samui Itinerary: The Perfect 4-Day Plan for 2026

Four days on Samui, no plan? This itinerary maps the island's best beaches, temples and day trips into four unhurried days, with real 2026 prices and honest travel times.

It is a four-day, three-night plan based in or near Chaweng, though it works just as well from Lamai, Bophut or Maenam - Samui is compact and the ring road connects everything. KOHME is the local island app: book activities, order food and arrange a scooter or airport transfer in one place, at local prices. Here is the plan at a glance.

Getting Around Koh Samui

Samui is big for the Gulf, with a 51 km ring road. A full loop is about 1.5 hours of driving, so distances add up once you add temples and waterfalls.

A scooter is the classic Samui move and cheapest for this plan - grab one for Day 2, when you cover the most ground. Arrange a scooter or car through KOHME rentals on Koh Samui and have it delivered to your hotel. Prefer not to drive? Book a taxi or airport transfer on Koh Samui for a fixed fare. On a scooter, wear the helmet and photograph existing scratches to avoid a deposit dispute.

Where to Stay by Area

Where you base yourself shapes the trip. Typical 2026 nightly rates for a decent mid-range room:

For a first trip pick Chaweng or Lamai - near the beach and central for day trips; Bophut is quieter and prettier, Maenam the value play.

Day 1: Chaweng & Lamai Beaches

Ease in gently on the two beaches that made Samui famous.

Morning. Start at Chaweng Beach, the island's longest, liveliest strip of white sand. The north end is calm and shallow, ideal for a first swim, with loungers and beach bars along the front.

Afternoon. Head 15 minutes south to Lamai Beach, broader and more laid-back. Nearby are the Hin Ta and Hin Yai rocks, the cheekily named grandfather and grandmother formations, worth a quick photo.

Evening. Chaweng's food choice is enormous, from street pad thai to seafood grills. Too tired to go out? KOHME does food delivery across Koh Samui at local menu prices, so a big Thai spread comes to your room without the tourist markup.

Day 2: The Island Loop (Big Buddha, Temples & Waterfalls)

Your sightseeing day, and why a scooter or car earns its keep. Start early to beat the heat.

Big Buddha (Wat Phra Yai)

Begin at the Big Buddha near Bang Rak. The 12-metre golden statue sits on a small islet and is visible from landing planes. Free entry (a donation is appreciated); mornings are cooler and quieter. Dress respectfully - shoulders and knees covered.

Wat Plai Laem

Minutes away, Wat Plai Laem is a striking temple built over a lake, with an 18-arm Guanyin and colourful Buddhist-Chinese design. Free, photogenic and far less crowded than the Big Buddha.

Na Muang Waterfalls

Cut inland to the free Na Muang waterfalls. Na Muang 1 is an easy walk with a swimmable pool when water is flowing (best in and just after the wet season); Na Muang 2 is taller and needs a short uphill hike. Skip the pushy ATV and elephant touts.

Fisherman's Village, Bophut

Finish on the north coast at Fisherman's Village in Bophut, restored wooden shophouses full of cafes, boutiques and seafood restaurants - the best spot for sunset drinks and dinner. On a Friday the weekly Walking Street market takes over. Rather not ride? These stops also combine into a guided KOHME half-day or full-day tour.

Day 3: Ang Thong Marine Park Day Trip

If you splurge once on Samui, make it this. Ang Thong National Marine Park is 42 limestone islands in emerald water about an hour offshore - the postcard image most people carry home. Tours leave from Na Thon or Maenam and usually include:

• The Emerald Lake (Talay Nai) on Koh Mae Ko, a hidden saltwater lagoon ringed by cliffs
• The Koh Wua Talap viewpoint, a short steep scramble to the classic Ang Thong panorama
• Kayaking among the karst islands and sea caves
• Snorkelling, plus a beach stop and lunch

Choose a slower, cheaper big boat or a faster speedboat with more park time - both full-day with hotel pickup. The 2026 prices:

Bring reef-safe sunscreen, a dry bag and shoes you can climb in. Book a day or two ahead through KOHME activities to compare operators and lock in transfers. The park closes seasonally in the roughest weather, so confirm it is running.

Day 4: Wellness, Food & Departure

Wind down. After the boat trip your legs will thank you for a slow morning.

Massage. Start with a Thai massage, widely available in Chaweng and Lamai for 300-500 THB per hour, the perfect antidote to yesterday's climbing and kayaking.

Brunch and beach. Samui's cafe scene is strong: smoothie bowls, proper coffee and healthy plates around Chaweng and Bophut. Squeeze in a final swim, or shop at Central Festival if it rains.

Departure. Samui airport (Bang Rak) is 15-20 minutes from Chaweng, so no need to leave early. Pre-book your airport transfer on KOHME so the ride is waiting at a fixed price.

What This Koh Samui Trip Costs in 2026

Rough per-person guide for four days, excluding flights and accommodation. Indicative and season-dependent.

All in, a careful traveller runs this itinerary on roughly 5,000-6,000 THB beyond a bed; a comfortable trip with taxis, a speedboat tour and nicer meals lands nearer 12,000-14,000 THB. The boat trip is where the money goes.

On timing, the driest months are February to April and June to August; October and November are the wettest, so front-load the Ang Thong trip then in case a sea day is cancelled.

Frequently Asked Questions

Is 4 days enough for Koh Samui?

Yes. Four days covers the highlights without rushing: a beach day on Chaweng and Lamai, an island loop for the Big Buddha, Wat Plai Laem, Na Muang waterfalls and Fisherman's Village, a full-day Ang Thong boat trip, and a final morning for a massage, a good meal and departure.

How do you get around Koh Samui?

The cheapest option is a scooter at roughly 200-300 THB per day for the 51 km ring road. Shared songthaew trucks run the main coast for 50-100 THB per hop, and private taxis or app rides cost around 400-600 THB from Chaweng to the airport. If you would rather not drive, book a car or airport transfer in the KOHME app.

How much does an Ang Thong Marine Park day trip cost in 2026?

A big-boat group tour runs about 1,500-2,500 THB per person and a speedboat trip roughly 2,500-3,500 THB. Most include hotel transfers, lunch, snorkelling and kayaking, but the 300 THB park entry fee is sometimes charged separately, so always check first.

Where should I stay on Koh Samui for a short trip?

Chaweng suits first-timers who want beaches, nightlife and the most restaurants. Lamai is cheaper and more relaxed, Bophut and Fisherman's Village are best for boutique stays and dining, Maenam is the quiet budget option, and Choeng Mon is a calm pocket near the airport.

What is the best time to visit Koh Samui?

The driest, sunniest window is roughly February to April, and June to August is also mostly dry. The heaviest rain falls in October and November, so if you visit then, put the Ang Thong boat trip early in your stay in case rough seas cancel a day.

Can I order food delivery while sightseeing on Koh Samui?

Yes. KOHME delivers to hotels, villas and many beach spots across Chaweng, Lamai, Bophut, Maenam and beyond at local prices. You can also book activities, an Ang Thong tour and scooter or car rental in the same app.
