Pattaya Scuba Diving Guide 2026
Pattaya is one of the most accessible scuba diving destinations in Southeast Asia — 25+ dive sites sit within a 40-minute boat ride from shore, covering everything from shallow coral reefs to purpose-sunk naval wrecks. You can book a two-dive day trip, including equipment and transfers, for around ฿2,200–฿3,200 per person from any of the PADI dive centres on Beach Road or in Jomtien.
This guide covers the best dive sites, snorkelling spots, what everything costs in Thai Baht, and which months give you the clearest water.
Quick Answer: Is Pattaya Good for Scuba Diving?
Yes — especially for beginners, wreck diving enthusiasts, and divers based in Bangkok who want an easy weekend trip. Pattaya won’t compete with Koh Tao or the Similan Islands for pristine reef, but it offers five wreck dives (including the famous HTMS Khram), year-round access, and genuinely affordable 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 operate day trips that include 2 dives with a surface interval for lunch.
Near Island Dive Sites
Koh Sak
Koh Sak sits about 8km from shore and is one of the most popular beginner dive sites in Pattaya. Depths range from 6–18 metres over a mixture of hard and soft coral gardens. You’ll regularly see butterflyfish, angelfish, parrotfish, and moray eels tucked into the reef.
Visibility here is fairly consistent at 5–10 metres even in lower-visibility months, which makes it a solid fallback site when the Far Islands are rougher. Koh Sak also has a small artificial reef area with a few smaller wrecks and concrete structures that attract nudibranchs and juvenile fish.
Koh Krok
A tiny island just 6km from Pattaya, Koh Krok is often the first open-water dive site for students doing their PADI Open Water course. The reef wraps around the island at 6–15 metres and is home to sea turtles — spotting one here is genuinely common, not a brochure promise.
The current can pick up on the north side in the afternoon, so most dives start early and use the south-facing reef entry.
Koh Larn (Coral Island)
Koh Larn is primarily known as a beach day-trip island, but the south-facing reef on the quieter side of the island has some decent diving. Depths reach 16–20 metres and you’ll find sea fans, scorpionfish, and occasional bamboo sharks 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, and 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, better visibility (8–15m on average), and a greater variety of fish.
The HTMS Khram wreck sits about 300 metres east of Ko Phai in 28 metres of water, making it easy to combine a reef dive with a wreck dive on the same trip.
Ko Man Wichai
Ko Man Wichai is the farthest accessible dive site from Pattaya for day trips, sitting roughly 30km offshore. The reef slopes from 10–25 metres and is one of the better sites in the region for larger pelagic species — barracuda schools, cobia, and the occasional bull shark have been reported. It’s not a guaranteed encounter, but the site sees less diver traffic than Ko Phai and tends to feel more natural.
Wreck Diving in Pattaya
Pattaya is widely regarded as 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 depth with the deck at 24 metres. Two 20mm gun turrets and a 40mm gun tower remain intact and are now encrusted 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 motionless in the shadow of the hull, and moray eels are everywhere. On a good visibility day (November–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). They’re positioned close enough that a two-dive trip can cover both. The wrecks have 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 (south of Pattaya, about 35km away). It’s one of the deeper accessible dives from Pattaya — deck at 24 metres, keel at 34 metres — and is best suited to Advanced Open Water divers. The wreck is larger than the naval vessels and more complex to navigate, with multiple deck levels and hold spaces.
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): The clear water on the south side of the island has coral at 1–5 metres depth. Gear hire on the island costs 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 include 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.

Best Time to Dive in Pattaya
| 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 you can dive in a 3mm wetsuit (or none at all) in peak season.

Tips for First-Time Divers in Pattaya
- Book through your hotel or direct with the shop — avoid street touts, who often collect a commission and take you to whichever shop pays the highest referral fee.
- Check the divemaster-to-student ratio — a 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. Missing it means missing the whole day.
- Don’t drink alcohol the night before — diving and a hangover are genuinely dangerous. Pattaya nightlife is legendary, but plan your dive days carefully.
- Bring a towel and sunscreen — surface intervals on the boat can be long, and the reflection off the water burns fast.
- Equalise early and often — descents on Pattaya’s wrecks are steep, and the ear pressure builds quickly. Signal your instructor if you feel 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?
It 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 is suitable for any confident swimmer. Koh Larn is the easiest option for family snorkelling.
How much does a full PADI Open Water course cost in Pattaya?
Expect to pay ฿9,500–฿13,500 (roughly NZD $420–$600) for a full PADI Open Water course including pool sessions, study materials, and 4 open water certification dives. Prices at the upper end typically include better equipment and smaller class sizes.
