Parc Marin d\

The flagship excursion from Koh Samui and the one we recommend above all others if you can only do one tour.

• Emerald Lake — a saltwater lake inside a mountain accessible via the viewpoint trail
• Snorkeling in crystal-clear water over coral reefs
• Beach time on pristine white-sand beaches

Price: 4,400 THB per adult, 2,200 THB per child (2-9). Duration: 7.5 hours. National park entry fee included. Important: Ang Thong closes from November 1 to mid-December annually due to monsoon conditions.

Koh Tan (pig island) & Île aux Cochons (Koh Madsum)

This tour is ideal for families with young children, beginners, and anyone who prefers calmer waters. The short boat ride means minimal travel time and more time in the water. The coral reefs around Koh Tan (pig island) are shallow and teeming with tropical fish.

Price: 2,800 THB per adult, 1,400 THB per child. Duration: 6 hours. Available year-round — the south coast is protected from monsoon swells.

Koh Rap BBQ

Koh Rap is one of Koh Samui's best-kept secrets. This tiny, uninhabited island off the south coast has a stunning white-sand beach that feels completely private. The highlight is a freshly prepared BBQ lunch right on the beach — grilled fish, seafood, chicken, and tropical fruits prepared by our crew while you swim and snorkel.

L\

Price: 3,500 THB per adult, 1,750 THB per child. Duration: 5-6 hours. Year-round availability.

Excursion Koh Phangan

Koh Samui's larger sister island is famous for the Full Moon Party, but it's equally impressive as a daytime destination. Koh Phangan has some of the most beautiful beaches in the Gulf of Thailand, including Thong Nai Pan Noi, Bottle Beach (Haad Khuat), Haad Salad, and Haad Yao.

Le trajet ne prend que 20-25 minutes en speedboat, vous laissant une journée complète pour explorer plusieurs plages, faire du snorkeling et déjeuner en bord de mer. En speedboat privé, vous pouvez arriver directement sur des plages isolées comme Bottle Beach — accessible uniquement par bateau.

Price: 4,000 THB per adult (shared excursion). Private speedboat from 18,000 THB for up to 10 guests. Duration: 7-8 hours. Year-round availability.

Koh Tao & Koh Nang Yuan

The longest day trip but arguably the most visually stunning. Koh Tao is Thailand's diving capital, and the waters around it have the best visibility and most diverse marine life in the region. Koh Nang Yuan, a trio of islands connected by a white sandbar, is one of the most photographed spots in all of Thailand.

C\

Price: 5,000 THB per adult, 2,500 THB per child. Duration: 10-12 hours. Best from December to April when seas are calmest. Note: Koh Nang Yuan charges a separate 100 THB entry fee.

Quelle Excursion Choisir ?

Avec autant d\

First Time in Koh Samui?

Start with Ang Thong Marine Park. It's the signature experience and the most diverse — you get kayaking, hiking, snorkeling, and incredible scenery in a single day. If Ang Thong is closed (November - mid-December), go for Koh Tan (pig island) & Pig Island instead.

Familles avec Jeunes Enfants ?

Koh Tan (pig island) & Pig Island is the clear winner. Short boat ride, calm waters, shallow snorkeling, and kids absolutely love the pigs. The Safari Tour is also excellent for families — no seasickness risk and plenty of excitement.

Couples & Lunes de Miel ?

Koh Rap BBQ for an intimate, almost private island experience with a romantic beach BBQ. Alternatively, a private speedboat charter to Koh Phangan for a day of beautiful beaches and total freedom.

Snorkelers & Plongeurs Sérieux ?

Koh Tao & Nang Yuan without question. The visibility and marine life diversity are unmatched. The long day is worth it for the underwater experience.

Voyageurs avec Petit Budget ?

The Safari Tour at 2,500 THB is the most affordable option and doesn't compromise on experience. For a water-based excursion, Koh Tan (pig island) at 2,800 THB offers outstanding value.

Grands Groupes (6+ Personnes) ?

Consider a private charter. For groups of 8-10, a private speedboat often costs less per person than individual shared tour tickets — and you get a custom itinerary, flexible schedule, and exclusive use of the boat. Read our Private vs Shared Tour comparison for detailed pricing.

Conseils de Réservation & Infos Pratiques

1. Book 2-3 days ahead for shared tours during peak season (December - March). Private charters need at least a week's notice.
2. Morning departures are best — calmer seas, better light for photos, and more active marine life for snorkeling.
3. Check what's included — our prices cover everything (park fees, lunch, equipment, transfers). Some operators exclude park fees or lunch to show lower prices.
4. Bring reef-safe sunscreen — regular sunscreen damages coral. Many tours now require reef-safe products.
5. Waterproof phone case — essential for boat trips. You'll want photos but phones and saltwater don't mix.
6. Motion sickness — if you're prone, take medication 30 minutes before departure. The waters around Koh Samui are generally calm, but the crossing to Koh Tao can be choppy.
7. Combine tours — if you have multiple days, we recommend Ang Thong + Koh Tan (pig island) + Safari for the most complete Samui experience.
