10 Days in Koh Samui — Itinerary with Phangan & Tao Add-Ons (2026)

Overview

Ten days on Koh Samui is enough to cover all four coasts, both major temples, two waterfalls, a full-day Ang Thong Marine Park boat trip — and still have 3 days left to add a ferry hop to Koh Phangan or Koh Tao. This guide builds a 7-day Samui core (Days 1-7), then splits Days 8-10 into two optional add-ons so you pick the ending that fits your trip.

If a full three-island loop with no fixed base appeals more, see the dedicated 10-day Gulf islands route, which spends roughly equal time on all three. This plan is different: it front-loads a complete Samui trip, then treats Phangan or Tao as a genuinely optional 3-day extension rather than a mandatory leg. For shorter trims of the same core route, see the 3-day, 5-day and 7-day itineraries, or the itinerary hub for all four side by side.

Key takeaways

• Days 1-7 cover Chaweng, Big Buddha, Ang Thong Marine Park, Maenam, two waterfalls and the south/west coast — a complete Samui trip on its own.
• Days 8-10 branch: stay on Samui, add Koh Phangan (ferry 20-50 min, 130-400 THB / ~3.50-11 USD), or add Koh Tao (ferry 1.5-2.5 hr, 600-1,200 THB / ~17-34 USD).
• Ang Thong Marine Park (Day 3) and any Days 8-10 ferry both need booking 2-3 days ahead, sooner in December-February.
• A 10-day Samui-only trip runs roughly 15,000 THB (~429 USD) budget to 40,000 THB (~1,143 USD) mid-range per person, per the trip cost guide; an island add-on adds 3,000-8,000 THB (~86-229 USD).
• Decide the Days 8-10 branch before booking flights out — Koh Tao’s airport option is Chumphon by ferry, not a direct Samui return, if you skip the return leg.

10-Day Koh Samui Itinerary at a Glance

Days 1-7 are fixed; Days 8-10 branch into three options depending on whether you stay on Samui or ferry out.

Day 1 — Arrival and Chaweng

Day 1 is a half-day: Samui Airport (USM) sits about 3 km from Chaweng Beach, a 10-15 minute ride by prepaid airport taxi (500 THB / ~14 USD) or shared minivan (from 130 THB / ~3.50 USD). Check in, then spend the afternoon in the water at Chaweng — the island’s longest stretch at roughly 7 km, with a calm swimming shelf near Chaweng Noi. Dinner along Beach Road runs 80-120 THB (~2.50-3.50 USD) for street food up to 400-800 THB (~11-23 USD) for a beachfront restaurant meal; save late-night Soi Green Mango for later in the trip if it’s on your list, per the Chaweng nightlife guide.

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

Wat Phra Yai (“Big Buddha”), a 12-meter golden statue on a causeway island about 20 minutes (~250-350 THB) from Chaweng, is free to enter and best visited before 10 AM. Wat Plai Laem, 5 minutes away, adds an 18-arm Guanyin statue over a lake — both temples together take 1.5-2 hours. In the afternoon, Choeng Mon Beach is a sheltered bay 10 minutes further for lunch and a swim, before finishing at Bophut’s Fisherman’s Village for dinner among converted Chinese shophouses; a Friday visit adds the weekly Walking Street market from about 5-10 PM.

Day 3 — Ang Thong Marine Park

The one full-day tour on the Samui leg. Boats depart Nathon or Bang Rak pier around 7:00-7:30 AM, reaching Ko Wua Talap first for a steep ~500-step climb to the archipelago viewpoint (45-60 minutes round trip). Standard group tours run 1,200-2,200 THB (~34-63 USD) per adult including lunch and snorkeling gear; the 300 THB (~8.50 USD) park entrance fee is sometimes billed separately. Many itineraries continue to Koh Mae Ko’s Emerald Lake, another ~500-step climb to a lagoon viewpoint, before returning to Samui by 4:30-5:30 PM. According to Ang Thong Marine Park’s official visitor guide, crossings can be choppy outside the December-February dry season. Book this tour 2-3 days ahead — sooner in December-February.

Day 4 — Maenam, a Slow Beach Day

Maenam Beach is 20-30 minutes (~200-300 THB) from Bophut — one of Samui’s longest beaches at roughly 5 km, with calm, shallow water that stays warm (28-30°C) year-round. Use the day to recover between the temple circuit and the interior waterfall run: a spa treatment (300-3,000 THB / ~8.50-86 USD) or a round at Santiburi’s 18-hole golf course fills the afternoon well. If Day 4 lands on a Thursday, Maenam’s Walking Street market runs roughly 5-11 PM; otherwise the beachfront restaurants cover dinner.

Day 5 — Na Muang, Wat Khunaram and Secret Buddha Garden

Na Muang Waterfalls, about 30 minutes (~350-450 THB) from Chaweng, pair an easy, family-friendly 18-meter fall with a swimming pool (Na Muang 1, free entry) against an 80-meter cascade reached by a steeper trail (Na Muang 2, adds 30-45 minutes). Ten minutes on, Wat Khunaram holds the preserved body of a monk who died in meditation — no admission fee, donations customary. Secret Buddha Garden, 15-20 minutes further into the hills, is a moss-covered hillside sculpture garden with one of the island’s best interior viewpoints (entry ~80 THB / ~2.50 USD). Finish with dinner in Lamai, Samui’s second-largest beach.

Day 6 — Hin Lad Waterfall and East-Coast Snorkeling

Hin Lad Waterfall near Nathon, 20-25 minutes (~250-350 THB) from Chaweng, is a 30-meter multi-tiered cascade at the end of a 1.2 km, 20-40-minute forest trail (free admission). Back on the east coast, Coral Cove is a boulder-framed bay for shore snorkeling, connected to Silver Beach by the roughly 1.5 km Coral Cove to Silver Beach route. Close the day at Lamai Viewpoint — a ~300-step trail (or a paid cable car) up to coastal views and the Valentine Stone, entry 100-300 THB (~3-8.50 USD) — arriving 30-45 minutes before sunset.

Day 7 — South and West Coast

Day 7 covers ground the shorter Samui itineraries skip: the quieter south and west coasts. Lipa Noi, about 30-35 minutes (~350-450 THB) from Lamai, faces west and is one of the island’s best sunset beaches. Continuing along the coast, Taling Ngam and the fishing pier town of Thong Krut offer a slower, less-developed side of Samui and a longtail boat departure point for nearby Koh Madsum (“Pig Island”). Use the evening to plan tomorrow: this is the decision point for Days 8-10.

Choosing Days 8-10 — Samui, Phangan or Tao

Three options work equally well from here, and the right one depends on what Days 1-7 left you wanting more of.

Whichever you pick, book the ferry 2-3 days ahead — both routes run 6-20+ sailings daily outside peak season, but December-January and Full Moon Party week sell out faster.

Add-On Option A — 3 Days on Koh Phangan

Day 8: Take a morning Lomprayah catamaran from Maenam pier (~30 min, 250-400 THB / ~7-11 USD) or Seatran Discovery from Bang Rak (~30-45 min, 330-355 THB / ~9.50-10 USD) to Thong Sala; travelers heading straight for Haad Rin can take the Haad Rin Queen direct from Big Buddha pier instead (~25-50 min, 199-495 THB / ~5.50-14 USD). Settle in and browse Thong Sala’s night market. Day 9: Visit Phaeng Waterfall (free, 10-15 minute walk from parking), then a beach — Thong Nai Pan for pale sand about 40 minutes from Thong Sala, or Haad Rin if your dates match the monthly Full Moon Party (2026 dates: 26 Sep, 27 Oct, 24 Nov, 24 Dec, as of Sep 2026). Day 10: Ferry back to Samui with the reverse crossing, timed 3-4 hours before any onward flight. Full detail on every operator and pier lives in the Koh Samui to Koh Phangan ferry guide.

Add-On Option B — 3 Days on Koh Tao

Day 8: Sail direct via Lomprayah from Maenam (~1.5 hr, 650-700 THB / ~19-20 USD) or Seatran Discovery from Bang Rak (~2 hr, 600 THB / ~17 USD) to Mae Haad Pier, then settle into Sairee Beach, Koh Tao’s main strip for divers and beach-focused travelers. Day 9: A two-tank fun dive for certified divers runs 1,800-2,800 THB (~51-80 USD); non-divers can join a snorkeling trip from 900-1,500 THB (~26-43 USD), often stopping at Koh Nang Yuan, a three-islet sandbar (separate 200-300 THB / ~5.50-8.50 USD park fee). Day 10: Return to Samui on the same operators in reverse, timed with a 3-4 hour buffer before your flight — Gulf ferries occasionally run late in choppy weather. Full operator and pier detail is in the Koh Samui to Koh Tao guide, and the complete three-island version of this trip is in the Gulf islands route.

Itinerary Variants by Traveler Type

• Couples/honeymoon: Swap Day 3’s group Ang Thong tour for a private speedboat charter (8,000-20,000 THB / ~229-571 USD for a group of 4-8), and pick the Koh Phangan add-on with a Thong Nai Pan base for a quieter beach — see the honeymoon guide.
• Families with kids: Skip Na Muang 2 and Hin Lad’s full climb, and take the “stay on Samui” branch for Days 8-10 rather than adding ferry logistics — see the with kids guide.
• Budget backpackers: Replace private taxis with songthaews, use Songserm for the cheapest ferry fares, and pick the Koh Phangan add-on over Koh Tao’s pricier dive costs — see the budget backpacker itinerary.
• Digital nomads: Treat Days 8-10 as a scouting trip for a longer future stay — Koh Phangan’s Srithanu area and Samui’s own coworking scene are both covered in the digital nomad and coworking guides.

Budget Breakdown

Per the Koh Samui trip cost guide, Days 1-7 on Samui alone run roughly 10,500-15,000 THB (~300-429 USD) budget to 28,000-40,000 THB (~800-1,143 USD) mid-range per person, scaling the daily 1,500 THB (~43 USD) and 4,000 THB (~114 USD) baselines across a week. Adding 3 more days shifts the total as follows.

Figures exclude the international flight in. Koh Phangan runs 20-30% cheaper per day than Samui for the same tier, which offsets most of its ferry cost; Koh Tao’s total runs slightly higher mainly due to diving or snorkeling trip prices.

Booking Timeline

Book the Ang Thong Marine Park tour (Day 3) at least 2-3 days ahead, up to a week in December-February. Decide your Days 8-10 branch before booking flights home, since a Koh Tao return adds a same-day ferry-to-flight connection that needs a 3-4 hour buffer. Flights on Bangkok Airways, Samui’s main carrier, are worth booking around 6 months out for peak season — see the when to book guide for hotel and villa lead times too. Reserve any Days 8-10 ferry 2-3 days ahead, and Haad Rin accommodation 4-5 nights out if your dates land on a Full Moon Party.

FAQ

Is 10 days enough for Koh Samui, Koh Phangan and Koh Tao?

Ten days is enough for a complete 7-day Koh Samui trip plus a focused 3-day add-on to either Koh Phangan or Koh Tao — not both. Covering all three islands properly needs closer to 10-12 days split more evenly, which the Gulf islands route lays out day by day.

Should I add Koh Phangan or Koh Tao to a 10-day Koh Samui trip?

Add Koh Phangan for beaches, waterfalls and nightlife, or Koh Tao for diving and snorkeling around Koh Nang Yuan. Phangan’s ferry is shorter (20-50 min) and cheaper (130-400 THB / ~3.50-11 USD) than Tao’s (1.5-2.5 hr, 600-1,200 THB / ~17-34 USD), making it the easier add-on if time is tight.

How much does a 10-day Koh Samui trip cost?

A 10-day Samui-only trip runs roughly 15,000 THB (~429 USD) per person at the budget tier or 40,000 THB (~1,143 USD) mid-range, per the trip cost guide. Adding Koh Phangan or Koh Tao for the last 3 days adds another 3,000-8,000 THB (~86-229 USD), excluding the international flight in.

Do I need to book the Koh Phangan or Koh Tao ferry in advance?

Book 2-3 days ahead outside peak season; both routes run frequent daily sailings, so short-notice tickets are usually available. During December-January and the week of a Full Moon Party, book further ahead, since boats and Haad Rin accommodation sell out fastest then.

Can I skip the ferry add-on and just stay 10 days on Koh Samui?

Yes — Days 1-7 already form a complete Samui itinerary, and Days 8-10 work just as well repeating a favorite beach, adding a second Ang Thong trip, or exploring day trips not covered elsewhere; see the day trips guide for options that don’t require a ferry.

What is the best way to split 10 days between Koh Samui and Koh Phangan or Koh Tao?

A 7/3 split — 7 days on Koh Samui, 3 days on one other island — keeps travel time manageable while still giving each destination enough time to feel unrushed. Splitting closer to even (5/5) is possible but starts to feel rushed on Samui’s side, since Ang Thong Marine Park alone takes a full day.
