5-Day Koh Samui Itinerary — Beaches, Ang Thong & Waterfalls

Overview

Five days is the itinerary length most first-time visitors to Koh Samui should plan for. It is long enough to cover the east coast’s main beaches, both of the island’s landmark temples, a full-day boat trip to Ang Thong National Marine Park, and a waterfall hike in the southern interior — without the rushed, one-stop-per-day pace a 3-day trip forces. This plan bases you in Chaweng on the east coast, moves at a moderate pace (one major activity per day plus beach time), and runs on a mid-range daily budget of roughly 1,500-2,500 THB (~43-71 USD) per person excluding accommodation.

It suits couples, friends, and families with older kids who want a mix of beach relaxation, one big-ticket excursion, and enough culture and nature to feel like they saw the island rather than just one strip of sand — families with younger children should check our dedicated with-kids itinerary instead. Solo travelers and budget backpackers can follow the same route and cut daily spend by roughly a third using the low end of every price range below, or see our full budget backpacker itinerary for an under-1,500-THB/day version.

Key takeaways

• Base in Chaweng — central, well-connected by taxi and Grab, and 15-20 minutes from Samui Airport.
• One full day is reserved for Ang Thong National Marine Park (~1,200-2,200 THB / ~34-63 USD per person) — book it before you land, since the best-reviewed boats sell out in high season.
• Two temples (Wat Phra Yai, Wat Plai Laem) and one waterfall (Na Muang) fit comfortably into the other four days alongside beach time.
• Total non-accommodation spend for 5 days runs roughly 7,500-12,500 THB (~214-357 USD) per person — see the full budget breakdown below.
• December-April gives the driest roads and calmest seas for the Ang Thong crossing; expect afternoon showers July-October.

5-Day Koh Samui Itinerary at a Glance

This 5-day plan mixes one full-day excursion, two half-day cultural or nature stops, and three beach afternoons, so no single day feels overloaded. Mornings are reserved for activities that are more pleasant before the midday heat (temples, waterfalls, boat departures); afternoons are for beach time; evenings are for food and markets. All costs are per person and exclude accommodation and flights.

Day 1 — Arrival and Chaweng Beach

Most Bangkok Airways and other domestic flights land at Samui Airport (USM) by mid-morning or early afternoon. Skip the queue for a Grab (it can’t collect passengers inside the terminal) and use the fixed-price taxi counter instead — about 400-500 THB (~11-14 USD) for the 10-20 minute, roughly 10 km run to Chaweng.

Morning — arrival

Clear immigration, collect the taxi counter voucher, and check in. If your room isn’t ready, leave bags at the hotel and walk straight to the beach — Chaweng hotels are almost all within a 5-10 minute walk of the sand.

Afternoon — Chaweng Beach

Chaweng is Koh Samui’s longest developed beach, a 7 km stretch of white sand split into North, Central and Chaweng Noi sections. Rent a lounger (100-150 THB / ~3-4.50 USD) or grab a kayak or paddleboard from a beach operator (300-500 THB / ~8.50-14 USD per hour) if you want to get in the water on arrival day rather than just adjust to the heat on the sand.

Evening — dinner and Soi Green Mango

Eat along the beach road — a mid-range Thai dinner runs 200-600 THB (~5.50-17 USD) per person — then walk Soi Green Mango, Chaweng’s main nightlife strip, for a low-key first-night drink. Save the late nights for day 4 or 5 once you’ve adjusted to the time zone.

Day 2 — Big Buddha, Wat Plai Laem and Choeng Mon

Day 2 covers the island’s two most photographed temples and swaps Chaweng’s crowds for a quieter northeast-coast bay before finishing at Bophut’s Fisherman’s Village.

Morning — Wat Phra Yai and Wat Plai Laem

Start early at Wat Phra Yai (Big Buddha Temple), a 15-20 minute, ~250-500 THB taxi ride northeast of Chaweng. The 12-metre golden Buddha, cast in 1972, sits on its own small island (Koh Fan) connected by a causeway; it’s free to enter (donations of 50-100 THB / ~1.50-3 USD are appreciated) and open daily 7 AM-6 PM. Climb the 73-step naga staircase before the mid-morning heat sets in. Two minutes further by road is Wat Plai Laem — also free, same hours — where an 18-armed Guanyin statue rises from a small lake full of koi and catfish you can feed. Together the two temples need 1.5-2 hours; see our guide to Buddhism on Koh Samui for background on the statues’ iconography.

Afternoon — Choeng Mon

From Wat Plai Laem it’s a 10-15 minute, ~150-250 THB drive to Choeng Mon, a sheltered bay on the island’s northeast tip with calm, shallow water, softer sand than Chaweng, and views across to two small offshore islets. It’s a good swap for a second beach stop if you want quieter water than Chaweng’s — fewer vendors, fewer sunbeds, and a noticeably slower pace.

Evening — Bophut Fisherman’s Village

Head into Bophut for dinner, a 10-15 minute drive from Choeng Mon. The restored teak shophouses of Fisherman’s Village hold boutique cafes and seafood restaurants (mid-range dinner 250-600 THB / ~7-17 USD); if it happens to be a Friday, stay for the Friday Walking Street market (5 PM-11 PM), with street food from about 50-150 THB (~1.50-4.50 USD) per dish and live music along the main lane.

Day 3 — Ang Thong Marine Park

This is the itinerary’s one full-day, no-beach-time day, and it’s the day to book furthest in advance.

Morning — departure

Boats to Ang Thong National Marine Park leave from Nathon or Bang Rak pier, typically between 7 and 8:30 AM depending on the operator; most tours include free hotel pickup from the east and north coasts around 6:30-7:30 AM. A standard big-boat tour costs 1,200-2,200 THB (~34-63 USD) per adult, including lunch, snorkeling gear, kayak use and — on most packages — the 300 THB (~8.50 USD) national park entrance fee (150 THB / ~4.50 USD for children 3-14); confirm this is bundled before paying, since some budget listings bill it separately on arrival. Speedboat tours cut travel time roughly in half for 1,800-2,800 THB (~51-80 USD).

Afternoon — islands, viewpoint and kayaking

Standard tours stop at two or three of the archipelago’s 42 limestone islands. The Ko Wua Talap viewpoint climb — about 500 steps, 30-45 minutes, rated a hard scramble in humidity — rewards you with a panorama over the scattered islands; the Emerald Lake viewpoint (Talay Nai) is a similarly steep 30-45 minute stair climb to an inland saltwater lagoon ringed by cliffs. Both sit inside the same park fee. Sea kayaking through narrow channels between islands (often included, or ~500 THB / ~14 USD extra for a double kayak) and a snorkel stop round out the afternoon before the boat turns back toward Samui by mid-to-late afternoon.

Evening — rest

Boats typically dock back at Nathon or Bang Rak between 4 and 5:30 PM. After a full day of sun, heat and a full-park entrance fee already spent, keep dinner simple and turn in early — day 4 starts with another outdoor morning.

Day 4 — Na Muang Waterfalls and the Southern Temples

Day 4 moves inland to the island’s jungle interior for waterfalls, then adds two contrasting temple stops before ending on the south-east coast.

Morning — Na Muang Waterfalls

Drive or taxi about 30 minutes (~350-450 THB) from Chaweng to Na Muang Waterfalls, off Route 4169 in the southern interior. Entry to both falls is free; parking costs 60 THB for a car or 20 THB for a bike (or park on the main road and walk ~20 minutes to skip the fee). Na Muang 1 is an 18-metre fall reached by a flat, five-minute walk from the car park — the easiest waterfall stop on the island. Na Muang 2 is taller at 80 metres but needs a steeper 30-40 minute uphill hike through jungle; skip it if you’re short on time or the trail is muddy after rain.

Afternoon — Wat Khunaram and Secret Buddha Garden

A short drive from the falls, Wat Khunaram houses the mummified body of Luang Pho Daeng, a monk who died in 1973, seated upright in a glass case — free entry, donations welcome, and strict modest dress (shoulders and knees covered) required. If you have another hour, add Secret Buddha Garden (also called Tarnim Magic Garden), a hillside sculpture park of 80-plus weathered stone statues set around a jungle stream; entry runs about 80 THB (~2.50 USD), and the rough access road is easiest by taxi or a sturdy rental scooter rather than a small automatic.

Evening — Lamai

Finish at Lamai Beach, roughly 25 minutes (~500-600 THB) from Chaweng and the island’s second-largest developed beach. If your visit lands on a Sunday, catch the Lamai night market for street food and souvenirs; any other night, the beach road’s restaurant strip covers Thai and international food at prices similar to Chaweng.

Day 5 — Snorkeling, Silver Beach and Departure

The final day keeps things light — two short beach stops with the island’s best shore snorkeling, timed around an afternoon or evening flight.

Morning — Coral Cove

Spend the morning at Coral Cove, a small 180-metre bay tucked between Chaweng Noi and Lamai with a shallow coral reef close to shore. Visibility is best before 10 AM, before wind and boat traffic stir up the water; access is free and it’s about 15-20 minutes (~250-350 THB) from Chaweng.

Afternoon — Silver Beach

Walk or drive 5-10 minutes further to Silver Beach (also called Crystal Bay), a roughly 250-metre stretch widely rated the island’s best snorkeling spot for its combination of clear water and easy shore access. Rinse off, grab a late lunch nearby, and allow buffer time before heading to the airport — traffic on the ring road between Lamai and Chaweng can add 15-20 minutes during peak afternoon hours.

Evening — departure

Head to Samui Airport, 15-25 minutes from Lamai depending on traffic, allowing at least 90 minutes before your flight for the small but often busy terminal. If your flight is late evening, add a last dinner in Chaweng or Bophut on the way.

Budget Breakdown for 5 Days

Excluding accommodation and flights, a mid-range 5-day trip runs roughly 7,500-12,500 THB (~214-357 USD) per person. Accommodation adds roughly 1,500-4,000 THB (~43-114 USD) per night for a 3-4 star hotel in Chaweng, on top of these figures.

Backpackers can push toward the low end (or below) by using songthaews instead of taxis, eating at village restaurants (50-100 THB / ~1.50-3 USD per meal) instead of beachfront ones, and booking the budget big-boat Ang Thong option. See our Koh Samui on a budget breakdown for a fuller cost-of-trip picture.

Booking Timeline — What to Reserve and When

Most of this itinerary can be booked on arrival, but two things benefit from advance planning, especially in the December-March high season.

• 2-4 weeks before: Book flights and accommodation in Chaweng; confirm your Ang Thong Marine Park tour operator and pickup time, since the best-reviewed boats fill up in peak months.
• 1 week before: Check the best time to visit forecast for your dates — heavy rain can cancel Ang Thong boat departures with little notice, so build in flexibility if you’re traveling November-January.
• On arrival: Confirm your airport taxi voucher price at the counter (fixed, no need to negotiate); arrange a rental scooter or a private driver for day 4’s waterfall-and-temple loop if you’d rather not rely on taxis for four separate stops.
• Day before Ang Thong: Reconfirm your pickup time and location with the tour operator by message the evening before — pickup windows shift by 15-30 minutes depending on how many hotels are on the route.

FAQ

Is 5 days enough for Koh Samui?

Yes — 5 days covers the east coast’s main beaches, both landmark temples, a full-day Ang Thong Marine Park trip and a waterfall hike without feeling rushed. Three days works for a stopover but forces you to skip Ang Thong; a week or more adds a second island like Koh Phangan or more downtime between activities.

Where should I stay for a 5-day Koh Samui trip?

Chaweng is the most practical base — central on the east coast, 15-20 minutes from the airport, with the widest choice of hotels, restaurants and transport links. Bophut is a quieter alternative with a similar level of convenience if you prefer a boutique, village feel over Chaweng’s livelier strip.

How much does a 5-day Koh Samui trip cost?

Budget roughly 7,000-12,500 THB (~200-357 USD) per person for 5 days excluding accommodation and flights, covering transport, the Ang Thong tour, entry fees and food. Add 1,500-4,000 THB (~43-114 USD) per night for a mid-range hotel in Chaweng.

Do I need to book Ang Thong Marine Park in advance?

It’s not strictly required outside peak season, but booking 1-2 weeks ahead is safer December-March, when the best-rated boats sell out. Confirm whether the 300 THB (~8.50 USD) national park entrance fee is included in your quoted tour price before paying.

Can I fit Koh Phangan or Koh Tao into a 5-day trip?

Not comfortably — a same-day round trip ferry to either island eats most of a day, leaving little time on the ground. If island-hopping matters more than depth on Samui, look at our 7-day or 10-day plans instead, which build in a proper overnight stay on a second island.

What’s the best order to do this 5-day itinerary in?

The order above (Chaweng arrival, temples, Ang Thong, waterfalls, snorkeling) works well because it front-loads the fixed-time Ang Thong departure early in the trip, leaving flexible beach days at the end that can shift if weather disrupts the boat schedule.
