Pattaya Scuba Diving Guide 2026
Pattaya is one of the more accessible scuba diving destinations in Southeast Asia — 25+ dive sites sit within a 40-minute boat ride from shore, from shallow coral reefs to deliberately sunk naval wrecks. A two-dive day trip with equipment and transfers runs ฿2,200–฿3,200 per person from PADI dive centres on Beach Road or in Jomtien.
This guide covers the best sites, snorkelling options, prices in Thai Baht, and which months give the clearest water.
Pattaya’s near-island reefs reach depths of 6–20 metres — good for beginners and experienced divers alike.
Quick Answer: Is Pattaya Good for Scuba Diving?
Yes — particularly for beginners, wreck diving, and divers based in Bangkok after an easy weekend trip. Pattaya won’t match Koh Tao or the Similan Islands for reef quality, but it has five wreck dives (including the famous HTMS Khram), year-round access, and honest prices. Visibility averages 5–12 metres on a normal day and can reach 15+ metres from November through February.
Pattaya Dive Sites: Overview
Pattaya’s dive sites fall into three groups:
| Group | Islands/Sites | Depth | Best For |
|---|---|---|---|
| Near Islands | Koh Larn, Koh Sak, Koh Krok | 5–18m | Beginners, snorkellers |
| Far Islands | Ko Man Wichai, Ko Phai (Bamboo Island) | 8–22m | Intermediate divers, marine life |
| Wrecks | HTMS Khram, HTMS Kut, HTMS Mataphon, Hardeep | 14–30m | Wreck diving, advanced divers |
Boat transfers from Pattaya Beach or Bali Hai Pier take 20–40 minutes depending on site. Most dive shops run day trips covering 2 dives with a surface interval for lunch.
Near Island Dive Sites
Koh Sak
Koh Sak sits about 8km offshore and is one of the most popular beginner dive sites in Pattaya. Depths run 6–18 metres over a mix of hard and soft coral. You’ll regularly see butterflyfish, angelfish, parrotfish, and moray eels in the reef. Visibility is fairly consistent at 5–10 metres even in lower-visibility months, which makes it a solid fallback when the Far Islands are rougher. There’s also a small artificial reef area with concrete structures that attract nudibranchs and juvenile fish.
Koh Krok
Six kilometres from Pattaya, Koh Krok is often the first open-water dive site for students doing PADI Open Water. The reef wraps around the island at 6–15 metres and sea turtles turn up regularly — not a brochure promise, an actual pattern. The current picks up on the north side in the afternoon, so most dives start early and use the south-facing reef entry.
The near-island reefs around Koh Sak and Koh Krok — shallow, colourful, and beginner-friendly.
Koh Larn (Coral Island)
Koh Larn is mainly known as a beach day-trip island, but the south-facing reef on the quieter side has decent diving. Depths reach 16–20 metres with sea fans, scorpionfish, and the occasional bamboo shark resting on the sandy bottom. Most dive shops combine a Koh Larn dive with a beach stop.
For full coverage of the island — ferries, beaches, food — see our Koh Larn Island Guide.
Far Island Dive Sites
Ko Phai (Bamboo Island)
Ko Phai is about 25km from Pattaya and requires an early departure (typically 7:30–8am) for a two-dive trip. The reef is noticeably better than the near islands — more coral coverage, visibility at 8–15m on average, and more variety. The HTMS Khram wreck sits about 300 metres east of Ko Phai in 28 metres of water, making it straightforward to combine a reef dive with a wreck dive on the same trip.
Ko Man Wichai
Ko Man Wichai is the farthest accessible day-trip site from Pattaya, roughly 30km offshore. The reef slopes from 10–25 metres and sees less diver traffic than Ko Phai, which makes it feel more natural. Barracuda schools, cobia and the occasional bull shark have been reported here — not guaranteed, but the right site if you’re looking for something beyond the standard near-island experience.
Wreck Diving in Pattaya
Pattaya is widely considered Thailand’s wreck diving capital. Five decommissioned naval vessels and a cargo ship have been deliberately sunk as artificial reefs since the late 1990s.
HTMS Khram
The most popular wreck in Pattaya and one of the best wreck dives in the Gulf of Thailand. The HTMS Khram is a 56-metre navy vessel deliberately sunk in 2003, resting at 28 metres with the deck at 24 metres. Two 20mm gun turrets and a 40mm gun tower remain intact and are now covered in coral and soft fans.
Marine life on Khram is exceptional for a wreck of its age: large schools of fusiliers and snappers circle the superstructure, lionfish hang in the shadow of the hull, and moray eels are everywhere. On a good visibility day in November through February, the entire wreck is visible from the surface.
Minimum certification: PADI Open Water. Penetration dives require Advanced.
HTMS Kut and HTMS Mataphon
These two sister ships were sunk together in the mid-1990s and rest at similar depths to the Khram (25–30 metres). Close enough that a two-dive trip can cover both. They’ve had more time to develop coral coverage — particularly soft corals — and attract large groupers, batfish and goatfish.
Hardeep Cargo Wreck
The Hardeep is a historic cargo ship wreck near Samae San, roughly 35km south of Pattaya. It’s one of the deeper accessible dives from here — deck at 24 metres, keel at 34 metres — and suits Advanced Open Water divers. The wreck is larger than the naval vessels and more complex to navigate, with multiple deck levels and hold spaces.
Wreck diving in Pattaya — the HTMS Khram is the most accessible and most visited of Pattaya’s five naval wrecks.
Snorkelling in Pattaya
You don’t need a dive certification to enjoy the water around Pattaya. The best snorkelling sites are:
- Koh Larn (Coral Island): Clear water on the south side has coral at 1–5 metres depth. Gear hire on the island runs around ฿150–฿200 for a set. Ferries from Bali Hai Pier run every 30–60 minutes for ฿30 each way.
- Koh Sak: Dive shops often take snorkellers on their boat trips (you stay at the surface while divers go deeper). Most shops charge ฿800–฿1,200 for a snorkelling-only trip with equipment.
- Ko Phai (Bamboo Island): Some far-island day trips include a snorkelling stop at the shallow side of Ko Phai.

Dive Centre Pattaya — Long-running operation on South Pattaya Road. Full PADI courses, day trips to near and far islands, speciality courses (wreck, deep, night). Well-maintained equipment.
Pattaya Scuba Adventures — Jomtien-based. Good for beginner courses and introductory dives. Small group sizes, consistent instructor quality.

Best Time to Dive in Pattaya
Flat seas and clear skies — the Gulf of Thailand’s dry season runs November through April.
| Month | Visibility | Sea Conditions | Notes |
|---|---|---|---|
| Nov–Feb | 10–15m | Calm | Best season — peak visibility, clearest water |
| Mar–Apr | 8–12m | Generally calm | Good diving, slightly warmer |
| May–Jun | 5–10m | Variable | Shoulder season — still diveable most days |
| Jul–Oct | 3–8m | Rougher | Rainy season — far island trips often cancelled |
November through February is the sweet spot. Water temperature stays at 27–30°C year-round so a 3mm wetsuit is plenty in peak season.

Tips for First-Time Divers in Pattaya
- Book direct with the shop — avoid street touts, who collect referral commissions and take you to whoever pays the most, not whoever’s best.
- Check the divemaster-to-student ratio — above 4:1 on open water certification dives is a red flag.
- Arrive the night before a far island trip — boats leave Bali Hai Pier at 7:30–8am. Miss the departure and you’ve missed the day.
- Don’t drink the night before — diving and a hangover are a bad combination. Plan your dive days around Pattaya’s nightlife, not the other way around.
- Bring a towel and sunscreen — surface intervals on the boat can be long, and the water reflection burns fast.
- Equalise early and often — descents on Pattaya’s wrecks are steep and ear pressure builds quickly. Signal your instructor if you feel any discomfort.
FAQ: Scuba Diving in Pattaya
Do I need a diving certificate to dive in Pattaya?
No — Discover Scuba (try dive) programmes let non-certified divers go to around 12 metres with a dedicated instructor. For independent dives and wreck sites below 18 metres you need at least PADI Open Water certification.
How far is the HTMS Khram wreck from Pattaya?
The HTMS Khram sits about 23km from Pattaya, near Ko Phai (Bamboo Island). A boat transfer takes roughly 35–45 minutes. Most dive shops run Khram wreck trips as a full day out with 2 dives — the wreck plus a reef dive nearby.
Is visibility good in Pattaya for diving?
Depends on the season. November to February offers the best visibility — typically 10–15 metres, sometimes more. During the rainy season (July–October) visibility can drop to 3–5 metres and swell can cancel far island trips entirely. Near-island sites are diveable most of the year.
Can children snorkel or dive in Pattaya?
Children aged 10+ can do the PADI Bubblemaker experience in a pool or very shallow water (max 2 metres). Children 10–14 can do PADI Junior Open Water certification with parental consent. Snorkelling on the surface suits any confident swimmer. Koh Larn is the easiest family snorkelling option.
How much does a full PADI Open Water course cost in Pattaya?
Expect to pay ฿9,500–฿13,500 for a full PADI Open Water course including pool sessions, study materials, and 4 open water certification dives. Prices at the upper end typically reflect better equipment and smaller class sizes.
