Koh Pai, Koh Rin & Monkey Island Pattaya: What to Expect at Each Stop on the 3 Islands Catamaran Tour

Most travel guides about the Pattaya 3 Islands Catamaran Tour give you a list of names — Koh Pai, Koh Rin, Koh Ped — and leave it there. What they don't tell you is what each island actually looks like, how long you spend there, what activities happen at each stop, what the marine life is like, and the specific things to know before you arrive.

This guide fills that gap. Whether you're deciding whether to book or already have your date confirmed, this is the island-by-island breakdown that helps you get the most out of each stop on the tour.

First: Where Are These Islands?

The three islands visited on the Pattaya Catamaran Party are part of the "Far Islands" group — a cluster of remote islands in the Gulf of Thailand located approximately 20–30 km southwest of Pattaya's coast. This distinguishes them significantly from Coral Island (Koh Larn), which most standard speedboat tours visit and sits only 7 km from the Pattaya shore.

The extra distance is the reason the tour uses an 82-ft luxury catamaran rather than a speedboat: the open-water crossing to the Far Islands is longer, and the catamaran's twin-hull stability makes it genuinely comfortable rather than a rough bounce across Gulf chop.

The tour departs from Ocean Marina Yacht Club in Na Jomtien at 09:30 AM and visits the islands in sequence: Koh Pai first for swimming and beach relaxation, Koh Rin for snorkeling and water activities, and Koh Ped (Monkey Island) last for sightseeing and photos before the DJ sunset cruise back to Pattaya.

Here's what to expect at each stop.

Island 1: Koh Pai (Bamboo Island) — White Sand Beach & Swimming

What It Is

Koh Pai (popularly known as Bamboo Island) is the largest island in the Far Islands archipelago, located approximately 21–23 km southwest of Pattaya's coast. The island is under the management of the Royal Thai Navy, which keeps it well-guarded, clean, and free of the overdevelopment that affects closer islands.

The name "Bamboo Island" is slightly misleading — the highlight of Koh Pai is its immaculate coastline. As the island is supervised for conservation by the Royal Thai Navy, its coasts are perfectly pristine and untouched. The main beach stretches across its eastern shore, where calm and shallow waters await, perfect for visitors to swim, sunbathe, and unwind.

What you're looking at when you arrive: a long, wide crescent of white sand backed by palm trees and low jungle vegetation, with clear turquoise water that stays shallow for a good distance from shore. No beach bars, no jet ski rentals, no parasailing operators. Just beach.

What You Do Here

Swimming is the primary activity at Koh Pai — the shallow, calm water near the shoreline is ideal. The seabed is sandy and clear with good visibility, and the water temperature in the Gulf is warm year-round (28–30°C during peak season).

Snorkeling is possible around the rocky edges of the island where coral formations begin. The coral reefs are bright, healthy, and can be viewed easily at the surface. You'll spot parrotfish, butterflyfish, clownfish, sea urchins, brain corals, and soft coral gardens. The snorkeling at Koh Pai is pleasant rather than spectacular — save your energy for the dedicated snorkeling stop at Koh Rin (the next island) where the coral and visibility are significantly better.

Beach time — Koh Pai is where most passengers simply swim, sunbathe on the bow nets of the anchored catamaran, or wade along the shoreline. The catamaran's onboard waterslide gets heavy use here too, with passengers launching from the upper deck directly into the clear water below.

For those who prefer to stay on land, Koh Pai's shore is equally wonderful. With its powdery white sand, it's the perfect place for sunbathing or simply exploring. There are also elevated trails along the island that offer breathtaking panoramic views of the Gulf of Thailand.

Practical Tips for Koh Pai

• Water shoes are helpful — the sandy beach is comfortable barefoot but the edges have sea urchins and occasional rocky patches. The catamaran provides a ladder into the water from the deck, which bypasses the rocky shoreline entry entirely.
• Naval oversight means no littering — Koh Pai is cleaner than most Thai beaches specifically because the Royal Thai Navy manages it. Respect this; don't leave anything on the beach.
• Morning light — arriving at Koh Pai in the morning (typically around 10:30–11:00 AM) gives the best light for photography, with the sun still low enough to avoid harsh midday shadows.
• The beach fills from the water, not the land — there's no road access to Koh Pai. Every person on the beach arrived by boat, which means the island stays substantially less crowded than Coral Island even on busy days.

Island 2: Koh Rin — The Snorkeling Highlight

What It Is

Koh Rin is a small uninhabited island and the undisputed snorkeling highlight of the three stops. Koh Rin is a remote island that offers pristine coral reefs and an abundance of marine life. Its untouched beauty and tranquility make it a true hidden gem among Pattaya's snorkeling spots.

The crown jewel of the Pattaya Far Islands is Koh Rin. This site boasts remarkable underwater landscapes featuring rocky formations, swim-throughs, and crevices. Divers can witness an abundance of marine life here, from small critters like nudibranchs to larger species such as bamboo sharks, moray eels, and schools of snappers and jacks.

The island is regulated by the Royal Thai Navy and uninhabited, which is why the reefs here are significantly healthier than at the more visited near-shore islands. What you're getting at Koh Rin is the closest thing to pristine Gulf of Thailand reef that's accessible on a standard day tour from Pattaya.

What You See Underwater

The marine life at Koh Rin is the best of the three island stops by a significant margin. Koh Rin is famous for its large coral bommies and overhangs where divers and snorkelers can spot bamboo sharks, barracuda, and schools of yellowtail fusiliers.

For snorkelers — as opposed to divers — the accessible zone near the surface holds:

• Reef fish in numbers: parrotfish, butterflyfish, angelfish, damselfish, wrasse, pufferfish, and triggerfish are all commonly sighted in the shallows
• Moray eels: spotted regularly in rocky crevices along the reef edge
• Leopard sharks: leopard sharks are commonly spotted at the Koh Rin dive site. These gentle creatures rest on the sandy bottom during the day, providing excellent photo opportunities. They are completely harmless. In shallower water they are sometimes visible to snorkelers without diving equipment.
• Coral formations: with an abundance of hard and soft corals, coral whips, and feather stars, snorkelers will not be disappointed with the cleaner water and aquatic creatures around these dive sites.

Visibility: visibility is usually up to 20 metres at Koh Rin during peak season (November to April), with optimal conditions in February to April. Even outside peak season, visibility of 8–12 metres is typical — enough to see coral formations clearly and spot fish moving through the reef.

What You Do Here

Koh Rin is the dedicated snorkeling stop. Snorkeling gear (mask, fins, snorkel) is provided as part of the tour package and crew members are in the water to assist less experienced snorkelers.

The kayaks and stand-up paddleboards are deployed at Koh Rin, giving non-snorkelers and resting swimmers another activity. The clear-bottom kayaks are particularly good here — you paddle over reef and sand and watch the fish beneath you without getting wet.

One important note on sea urchins: sea urchins seem to thrive in this area, so extra caution should be taken for bare-footed swimmers and snorkelers. Wear fins when snorkeling, stay off the reef edges, and don't stand on the seabed. The crew will brief you before entering the water.

Practical Tips for Koh Rin

• This is the most important stop for snorkeling — if you're going to put on the gear once all day, Koh Rin is where it pays off most. The coral and fish diversity here is meaningfully better than at Koh Pai.
• Bring an underwater camera — the visibility and marine life at Koh Rin justifies capturing it properly. A waterproof phone pouch works for surface photos; a GoPro or waterproof compact camera gives you better results below.
• Don't skip the kayaks — even if snorkeling isn't your thing, the clear-bottom kayaks at Koh Rin are a genuinely different way to experience the reef. You can see the fish without getting wet.
• Best season for Koh Rin: November to April for maximum visibility. The tour still runs in shoulder season (May, October) but visibility varies more.

Island 3: Koh Ped (Monkey Island) — Sightseeing & Photo Stop

What It Is

The third and final island stop before the DJ sunset cruise home is Koh Ped — universally known as Monkey Island. Monkey Island is the permanent residence of Thai Samae Monkeys. Thousands of these friendly yet cheeky primates have made their home in the island's low-lying vegetation and thrive in huge numbers, especially along the southern and eastern shorelines.

Koh Ped is a small island with low tropical forest vegetation and rocky pebble beaches. It is inhabited by hundreds of native Thai Samae monkeys who scramble over its rocky shores to greet any boats that arrive. There is also an interesting mermaid statue and a small Buddhist shrine on its north-eastern beach, both of which make for a nice photo opportunity.

Koh Ped is the most unusual stop of the three — there's no beach to speak of and no swimming or snorkeling here. It's a sightseeing and photo stop, and it works perfectly as the final island visit before the boat transitions into party mode for the sunset return cruise.

What Actually Happens at Monkey Island

Be honest with yourself before this stop: many people imagine a large island attraction with lots to do once they arrive. In reality, Monkey Island is usually a short stop on a wider boat trip. Usually 20 to 40 minutes is enough for most visitors.

What you'll see: dozens to hundreds of Thai macaques on the rocky shoreline, in the vegetation, and — once they spot the boat — making their way toward the water's edge in anticipation of food. The crew typically brings fruit scraps and snacks to the shore. Watching a hundred macaques converge on the feeding area is chaotic, noisy, and genuinely memorable.

The monkeys are wild, not domesticated. The visit goes well when people stay calm, keep their distance, and stop treating the monkeys like pets. Feeding makes behavior more aggressive and turns the stop into something worse for both visitors and animals.

Monkey Island Safety: What You Need to Know

This is the section most tour descriptions gloss over. The monkeys at Koh Ped are not dangerous, but they are opportunistic and bold. Here's what experienced visitors consistently report:

They will approach you. Once the crew brings food near the shoreline, monkeys come very close — sometimes within arm's reach. This is fine if you stay calm and don't make sudden movements.

They will grab for food and shiny objects. Sunglasses, snack bags, phone cases, small bags, and anything that looks like it might contain food are at risk if you hold them loosely. Keep sunglasses on a strap and phones in your pocket or held firmly.

Don't feed them directly from your hand. Monkeys that associate human hands with food become more aggressive about getting it. Place food on the ground rather than hand-feeding. The crew manages this process — follow their lead.

Don't try to touch or pick up the monkeys. They may bite if they feel cornered or threatened. While some visitors come to feed monkeys on the beach, it's advised not to touch them due to their natural behavior.

Children should stay close to adults throughout this stop. The monkeys are small — roughly the size of a cat — but fast and unpredictable. A child holding a snack bag is an obvious target.

The good news: thousands of visitors stop at Koh Ped every year without incident. Following the crew's guidance and keeping a respectful distance makes this stop entirely safe and genuinely fun.

What to Photograph at Koh Ped

Beyond the monkeys themselves, Koh Ped has two photogenic landmarks worth finding:

The mermaid statue — a stone mermaid figure on the northeastern beach. It's an unusual and quietly beautiful photo stop, often overlooked by visitors focused entirely on the monkeys.

The Buddhist shrine — a small spirit house and shrine on the rocky shoreline. A moment of quiet that contrasts sharply with the chaos of the monkey feeding area.

Best camera tip: Use your phone with a protective case or hold it firmly. The monkeys genuinely will take an unattended phone if it's left on a surface.

Practical Tips for Koh Ped

• This is a viewing stop, not a swimming stop — the rocky shoreline and absence of a proper beach mean Koh Ped isn't for swimming. Relax on deck and enjoy the spectacle from the boat or a safe distance from the shore.
• Secure loose items before disembarking — leave bags and valuables on the boat. Take only your camera or phone (held or in a wrist strap) to the shore.
• Don't expect a long stop — 20–35 minutes is typical. It's the perfect length for what the island offers.
• The transition from Koh Ped to party — after leaving Monkey Island, the catamaran begins the return cruise to Pattaya. This is when the DJ takes over, the music starts, and the onboard party begins. The timing is perfect: you've had your three island experiences and now the boat transforms for the sunset.

The Sunset DJ Cruise: The Fourth "Stop" Nobody Talks About

The 3 Islands tour itinerary lists three island stops, but there's a fourth experience that many guests remember most vividly: the DJ sunset party on the return cruise.

After departing Koh Ped, the catamaran heads back toward Pattaya as the afternoon sun begins its descent. The DJ setup powers up, the dance deck opens, and the boat becomes a floating party for approximately 90 minutes on the open Gulf.

The cocktail bar is open (drinks available for purchase at approximately ฿320 each), the music covers everything from Thai pop to international hits to EDM depending on the crowd, and the sunset — watched from a moving 82-ft catamaran with the Pattaya skyline slowly appearing on the horizon — is legitimately spectacular.

This isn't a token gesture. Guests consistently rate the sunset cruise as the highlight of the full day — the moment that makes the catamaran tour categorically different from any other Pattaya water activity. Plan your drinks budget accordingly, put the phone down for at least part of it, and enjoy what you came for.

What to Pack for the 3 Island Stops

Each island has slightly different requirements. Here's a stop-specific packing guide:

For Koh Pai:

• Swimwear (already on)
• Reef-safe sunscreen SPF 50+ — reapply before this stop
• Water shoes optional but useful for rocky shoreline entry
• Camera for beach and aerial-style photos from the bow nets

For Koh Rin:

• Your own snorkel mask if you have one (provided gear fits most people but personal masks seal better)
• Underwater camera or waterproof phone case — this stop justifies it
• Fins (provided) — wear them; the sea urchin risk is real

For Koh Ped:

• Phone in a wrist strap or secure grip
• Small bills if you want to buy snacks for monkey feeding (crew provides food but you can contribute)
• No loose bags, dangling jewellery, or unsecured sunglasses

For the Sunset Cruise:

• Light layer (the boat moves fast on the return and ocean wind cools quickly after sunset)
• Cash for cocktails (฿320 approximately per drink; card not always accepted at the onboard bar)
• Dance shoes are optional — the deck gets lively
