Koh Samui, Koh Phangan & Koh Tao — 10-Day Island-Hopping Route

Overview

Ten days is the minimum for a proper Thailand Gulf islands itinerary that covers Koh Samui, Koh Phangan and Koh Tao without rushing every ferry connection. This route spends four days on Koh Samui (beaches, temples, Ang Thong Marine Park, a waterfall), two on Koh Phangan (beaches and jungle waterfalls, with an optional Full Moon Party overlay), two on Koh Tao (diving or snorkeling), and reserves the last two for ferry days and a buffer before flying home.

The three islands sit in a line up the Gulf of Thailand, connected by a well-run network of catamarans and ferries, so no leg takes longer than about two and a half hours. Base in Bophut or Maenam on Koh Samui — both sit a few minutes from the Lomprayah and Seatran piers that start this route — then move to Thong Sala or Haad Rin on Koh Phangan, and Sairee Beach on Koh Tao, the standard base for divers and beach time alike.

Key takeaways

• 10 days covers all three islands at a comfortable pace: 4 on Koh Samui, 2 on Koh Phangan, 2 on Koh Tao, 2 for ferry/buffer days.
• Every inter-island leg runs 20 minutes to 2.5 hours by Lomprayah, Seatran Discovery or Songserm — fares from ~130-700 THB (~3.50-20 USD) one way.
• Base near Bophut or Maenam on Samui to minimize the transfer to the first ferry pier.
• Koh Tao is Thailand’s budget diving hub — a two-tank dive runs ~1,800-2,800 THB (~51-80 USD); non-divers snorkel from ~900 THB (~26 USD).
• Build in one buffer day before the return flight — Gulf ferries do get cancelled or delayed in rough seas, mainly November-December.

Ferry Legs — Operators, Times & Fares

Three inter-island ferry legs carry this whole route, and every one of them is covered by more than one operator, so a delay or full boat rarely strands you. Figures below are collected from operator timetables as of Sep 2026; always recheck the current schedule before booking, since Gulf ferry times shift with the monsoon.

Full detail for each of these legs — every departure time, seasonal notes and which pier suits which Samui beach — lives in our dedicated guides: Koh Samui to Koh Phangan ferry and Koh Samui to Koh Tao. Book Lomprayah directly at lomprayah.com or compare all operators on 12Go Asia; both list current timetables.

Children (roughly ages 3-11) typically pay 50-70% of the adult fare on every operator above. None of these boats carry vehicles — only Raja Ferry’s car ferry from Lipa Noi does, and it does not run to Koh Tao, so this route is on foot and songthaew throughout.

Days 1-2 — Koh Samui Highlights

Koh Samui opens this itinerary with two easy days built around Chaweng for arrival and Big Buddha for culture, both a short taxi ride from a Bophut or north-coast base. Landing at Koh Samui Airport in the morning leaves the whole first afternoon free.

Day 1: check in near Bophut, then head to Chaweng for the afternoon — Samui’s longest beach and the easiest base for restaurants, watersports rental and nightlife. Return to Bophut’s Fisherman’s Village for dinner among the converted shophouses; if it’s a Friday, the weekly night market adds street food stalls until late.

Day 2: visit Wat Phra Yai (Big Buddha), a 12-meter gold statue visible from the ferry approach, then Wat Plai Laem next door for its 18-armed Guanyin statue and lagoon setting — both temples sit within 10 minutes of each other and are free to enter (small optional donation). Spend the rest of the afternoon at Bophut beach, and stay for sunset; the shallow, calm water here suits a slower pace than Chaweng.

Day 3 — Ang Thong Marine Park

A full-day boat tour to Ang Thong Marine Park is the highlight of the Koh Samui leg, and it needs the whole day, departing around 08:00 and returning by 17:00. Tours run 1,200-2,200 THB (~34-63 USD) per person, including a national park entry fee, lunch and snorkeling gear, and depart from Nathon or Bang Rak pier depending on the operator.

The park’s 42 islands include Ko Wua Talap, where a steep 30-45 minute climb reaches a viewpoint over the archipelago, and the Emerald Lake, a landlocked saltwater lagoon reached by a short trail from the main beach. Kayaking and snorkeling stops fill the middle of the day. Book through a Samui tour desk or hotel a day or two ahead — capacity is limited and tours sell out in high season (December-February).

Day 4 — Waterfalls, Temples & Packing for the Crossing

Day 4 mixes nature and culture on Koh Samui’s south side before the ferry crossing begins the next morning. Start at Na Muang Waterfalls, a two-tier fall reachable by a short paved path (Na Muang 1) or a steeper 30-minute trail (Na Muang 2); entry is free, and the pools are best for swimming just after the rainy season (October-January).

Continue to Wat Khunaram to see the mummified monk displayed in a glass case, then Secret Buddha Garden in the hills above, a hillside sculpture garden reached by a rough 30-40 minute drive up Route 4169’s side roads — a rented scooter or hired driver both work. Finish with dinner in Lamai, then pack for an early ferry: whichever operator you choose (see the ferry legs table above), check-in closes 30 minutes before departure.

Day 5 — Ferry to Koh Phangan

Board a morning Lomprayah catamaran from Maenam (Pralarn) pier (~30 minutes, 250-400 THB / ~7-11 USD) or a Seatran Discovery ferry from Bang Rak (~30-45 minutes, 330-355 THB / ~9.50-10 USD); both land at Thong Sala, Koh Phangan’s main pier. Travelers heading straight to the Full Moon Party beach can instead take the Haad Rin Queen direct from Big Buddha pier (~25-50 minutes, 199-495 THB / ~5.50-14 USD), skipping the songthaew transfer.

From Thong Sala, a songthaew (40-60 THB) or taxi covers the last stretch to Haad Rin or a north-coast resort. Spend the afternoon on the beach nearest your hotel, then explore Thong Sala’s night market in the evening for the island’s cheapest and most varied food stalls.

Days 6-7 — Koh Phangan Beaches & Waterfalls

Koh Phangan trades Samui’s polish for a scrappier, more jungle-covered island, best explored by rented scooter. Start Day 6 at Phaeng Waterfall, the most accessible fall on the island, a 10-15 minute walk from the parking area; entry is free. In the afternoon, head to Thong Nai Pan on the northeast coast (a twin-bay stretch of pale sand, about 40 minutes from Thong Sala) or Bottle Beach, reachable only by longtail boat or a steep scooter track, for a quieter alternative to Haad Rin.

If your dates land on the monthly Full Moon Party — the next confirmed 2026 dates are 26 September, 27 October, 24 November and 24 December — Day 6 or 7 evening is the natural slot: entry runs free to a few hundred baht at the gate, with drink prices spiking on the night itself. Travelers skipping the party can instead book a snorkeling day trip (800-1,500 THB / ~23-43 USD) or a half-day yoga or Muay Thai session, both widely available around Srithanu and Haad Rin. Use Day 7 to recover, pack, and confirm your Day 8 ferry booking.

Day 8 — Ferry to Koh Tao

Catch a Lomprayah (~1-1.5 hr, 450-650 THB / ~13-19 USD), Seatran Discovery (~1-1.75 hr, 500-650 THB / ~14-19 USD) or budget Songserm (~1.5 hr, 350-450 THB / ~10-13 USD) boat from Thong Sala to Mae Haad Pier on Koh Tao — all three operators run this leg, with a combined 5-7 sailings a day. Confirm the day’s schedule at the pier the afternoon before, since departure times shift seasonally.

Settle into Sairee Beach, Koh Tao’s main strip and the natural base for both divers and beach-focused travelers, then spend the evening at one of the beachfront bars for sunset. If diving is on the agenda, most dive shops offer a free briefing and gear-fitting session the evening before a course or fun dive starts.

Day 9 — Diving and Snorkeling on Koh Tao

Koh Tao is Thailand’s main budget diving hub, and Day 9 is built around the water. A two-tank fun dive for certified divers runs about 1,800-2,800 THB (~51-80 USD); non-divers can join a snorkeling boat trip from around 900-1,500 THB (~26-43 USD), often including a stop at Koh Nang Yuan, a three-islet sandbar connected by a shallow sand spit and one of Thailand’s most photographed viewpoints (separate marine park fee, 200-300 THB / ~5.50-8.50 USD).

Travelers with more time on a future trip could extend this stop for a 3-4 day PADI Open Water course (roughly 9,000-12,000 THB / ~257-343 USD), but a single day is enough for a taste of Koh Tao’s reefs on this route. Spend the evening back on Sairee Beach’s sunset strip, and confirm tomorrow’s return ferry time before turning in.

Day 10 — Return to Koh Samui and Departure

Ferry back to Koh Samui on Lomprayah (Mae Haad → Maenam or Nathon, ~1.5-2 hr, 650-700 THB / ~19-20 USD) or Seatran Discovery (Mae Haad → Bang Rak, ~2 hr, 600 THB / ~17 USD). Time the sailing to land with at least 3-4 hours before your flight — allow 60-90 minutes for the taxi transfer plus airport check-in, more if landing at Nathon rather than Bang Rak, which sits closer to the airport.

If the schedule is tight, consider flying out of Koh Samui Airport the following morning instead and using Day 10 purely as a buffer — Gulf ferries occasionally run late or get rescheduled in choppy conditions, and a same-day flight connection leaves no margin for a delay.

Booking Timeline

• 8-12 weeks out: book flights into and out of Koh Samui Airport (USM); confirm dates against the Full Moon Party calendar if that’s part of the plan.
• 4-6 weeks out: reserve accommodation in Bophut/Maenam, Thong Sala or Haad Rin, and Sairee Beach — Haad Rin fills up fastest around party dates and December-January.
• 1-2 weeks out: book the Ang Thong Marine Park tour and any Koh Tao dive course in advance; both have limited daily capacity in high season.
• 2-3 days out: book Lomprayah or Seatran Discovery ferry tickets online for both crossings — walk-up tickets are usually available outside December-January but riskier around holidays.
• Day before each ferry: reconfirm the departure time at the pier or on the operator’s site; Gulf schedules shift with weather and season.

FAQ

How many days do I need for Koh Samui, Koh Phangan and Koh Tao?

Ten days covers all three islands at a workable pace: 4 days on Koh Samui, 2 on Koh Phangan, 2 on Koh Tao, and 2 for ferry transfers and a departure buffer. Seven days is possible by cutting one Koh Samui day and one Koh Phangan day, but it leaves no slack if a ferry runs late.

What is the cheapest way to island-hop between Koh Samui, Koh Phangan and Koh Tao?

Songserm is the cheapest scheduled operator on both Gulf crossings, with fares from about 200-450 THB (~5.50-13 USD) per leg versus 330-700 THB (~9.50-20 USD) on Lomprayah or Seatran Discovery. Songserm boats are slower and less frequent, so budget extra buffer time around each crossing.

Can I do this route in reverse, starting from Koh Tao?

Yes — every ferry operator on this route runs both directions on the same schedule, so starting from Koh Tao (reached via Chumphon on the mainland) and finishing on Koh Samui works just as well. Flip the day plan and keep the same fares and durations.

Do I need to book ferry tickets in advance?

Book 2-3 days ahead for Lomprayah or Seatran Discovery in high season (December-January) or around Full Moon Party dates; outside those windows, walk-up tickets are usually available the same morning. Songserm rarely sells out but has far fewer daily departures.

Is this itinerary suitable for non-divers?

Yes — Koh Tao’s snorkeling day trips (from ~900 THB / ~26 USD) and Koh Nang Yuan visit work well without diving certification, and Koh Phangan’s beaches and waterfalls need no water skills at all. Only the optional PADI course variant requires a multi-day commitment.

What’s the biggest risk factor on this itinerary?

Monsoon-season sea conditions (roughly November-December) are the main risk — smaller, slower boats like Songserm get cancelled first in rough weather, and Lomprayah and Seatran sailings can run late. Build a buffer day before any flight or onward connection during these months.
