Koh Samui adventure activities

Six ways to get the pulse up

The best ones are the ones a group can do together in half a day, with pickup from the villa.

• A jet ski safari to Pig Island and Koh Tan
• An ATV tour through the jungle to a waterfall
• A zipline over the rainforest canopy
• A session at the shooting range in Bophut
• Go-karts by Chaweng Lake, open until midnight
• Wakeboarding or parasailing off the main beaches

Pick two for one day, and keep the evening free. Ask Tanner which two suit your group.

At a glance

Here's how five of them compare, with prices as each listing shows them today. Wakeboarding and parasailing are quoted by Tanner for your day.

Every activity runs with a guide or an instructor, so nobody rides or shoots alone. Ask Tanner to line up the two you want on the same day.

Jet skis: the island safari

Do your jet ski in Koh Samui as a guided safari, with a guide on his own jet ski, not a rental from the sand.

The safari runs past Laem Sor Pagoda to a hidden lagoon and a snorkelling reef at Koh Tan, then the long beach at Koh Mat Sum, home of Pig Island. Pickup, snorkel gear, water and life jackets are included.

Up to 2 people share each jet ski, and the driver must be 18 or over. Koh Mat Sum charges a small landing fee, about ฿50, in cash.

For a group that would rather ride in comfort, a private boat to the same islands is the calmer way. See Koh Samui yachts, and ask Tanner which suits your crew.

What a jet ski costs

Each operator sets its own price by the time on the water: a 30-minute beach circuit costs the least, a guided safari more, and a private half-day island tour the most.

The Pig Island safari starts from about US$213 a jet ski, with up to 2 people on each, so a pair splits it.

Circuit rentals run from operators on Chaweng and Lamai beaches. Get the full price in writing before anyone rides. Ask Tanner for the all-in price for your group first.

How we book the jet skis

We book jet skis only with operators we know, so the price is agreed before anyone rides.

Photograph the jet ski before you ride, and leave a copy of your passport, never the real one.

Nobody drinks before driving a jet ski.

Insider tip: if anything is wrong after the ride, don't pay on the spot. Call Tanner, and he sorts it out with the operator.

ATVs: the jungle and the waterfalls

It's a guided ride on the dirt trails in the hills, through jungle and streams.

Samui Quad has run tours from Maenam on the north coast since 2002. Pick the 1-hour or the 2-hour ride, both with hotel pickup. The 2-hour route stops at a seasonal jungle waterfall and a trail-side bar.

You get a safety briefing first, and you wear the helmet and gear the whole way. Insider tip: wear clothes and shoes you're happy to get muddy, because the trails cross streams and soft ground. Ask Tanner to book the 2-hour ride, the one with the waterfall.

What an ATV tour costs

Samui Quad prices by the ride: the 1-hour ride costs less, and the 2-hour ride adds the waterfall stop. The table above shows today's listed prices.

Hotel pickup is included on both rides.

Ask Tanner to price the ride for your whole group.

Ziplines: the rainforest lines

The zipline in Koh Samui is a guided run of platforms and cables through the rainforest canopy.

Samui Zipline at Lipa Noi runs two courses, Ticket2Attraction lists: 18 platforms with a 300 m longest line, or 16 platforms with a 250 m longest line.

It opens 9am to 5pm, with hotel transfers both ways.

Riders must weigh 20 to 105 kg. Tree Bridge Zipline is the other big course, with a jungle cafe; its listings disagree on the details, so Tanner confirms them when he books. Ask Tanner which course fits your group.

The shooting range: how a session works

The shooting range in Koh Samui is in Bophut, open 8am to 5pm, with handguns, rifles and shotguns, Forever Vacation lists.

The age limit is often 18, so we check it for your group first.

An instructor runs the safety briefing and stays with you.

Prices are set by the gun and the number of rounds. Ask Tanner to book the range for the hour before lunch.

Go-karts, wakeboarding and parasailing

Koh Samui's other fast hours are go-karts at Chaweng Lake, a cable wake park and parasailing off the main beaches.

EasyKart at Chaweng Lake has a beginner track of about 300 to 350 m and a racing track of about 800 to 900 m, open daily from 10am to midnight.

Regular karts are for ages 12 and up, at least 140 cm tall.

Go-karts after dark are an easy start to a Chaweng evening. Ask Tanner to book the fast karts for the whole group.

When to go

February to April is the driest stretch, the Thai Meteorological Department says (checked November 2026). Our Koh Samui best time guide has it month by month.

November is the wettest month, with about 445 mm of rain, and October to December brings choppier water, so we plan the jet ski safari for a calm morning.

The ATV trails get muddier in the rain, which some riders love, and the shooting range and go-karts run in any weather.

On a wet day, swap the jet skis for the ATV or the go-karts. Ask Tanner to keep a back-up plan ready.

An adrenaline day for the group

The best day is two activities, a long lunch and a rest at the villa before the evening.

The easy plan: the jet ski safari in the morning, lunch, then the ATV or the zipline in the afternoon.

Book everyone into the same session, so the group stays together.

Then back to the Koh Samui pool villas to rest before ARKbar on Chaweng Beach. Plan it with Tanner, and the van is waiting.

Where to ride a jet ski in Koh Samui

The best jet ski in Koh Samui is the guided safari out to Koh Tan, Koh Mat Sum and Pig Island.

You ride in a line behind the guide, stop to snorkel off the small islands, and land on the sand with the pigs.

Short circuits run off Chaweng and Lamai beaches. They're fine for 30 minutes of speed, but the safari is the one the group remembers.

Tanner's pick: the morning safari, then the zipline after lunch. Ask Tanner to hold the morning slot.

What to wear and bring

On the water, wear swim shorts, a rash top and plenty of reef-safe sunscreen. The snorkel gear comes with the safari.

For the ATV and the zipline, closed shoes and clothes that can take the mud.

Carry a photocopy of your passport for the jet ski desk. EasyKart asks for closed shoes too.

Keep phones in a dry bag on the boat days, and save the drinks for the villa afterwards. Ask Tanner what else to pack for your day.

Next: plan your adrenaline day

The next step is to pick your two activities, then the evening after them.

See things to do in Koh Samui for the rest of the trip. The boat day to Ang Thong is off from 1 November to 15 December 2026 while the marine park is closed, so take a Koh Tao day in that window instead.
