Why Dive in China in 2026?
China rarely appears on the global list of diving hotspots next to Indonesia, Thailand, or the Maldives, yet it offers something unique: diverse dive ecosystems across tropical, subtropical, and cold-water regions in one country.
Key Reasons to Consider China for Diving
- Tropical coral reefs in the South China Sea
- Cold-water diving in Dalian’s kelp forests
- Volcanic seabeds around Weizhou Island
- Marine conservation projects in Hong Kong
- Less crowded offshore reefs in the Paracels
The Chinese domestic scuba community has expanded rapidly since 2022. Based on internal industry estimates, recreational diver certifications in China grew approximately 25–35% between 2023 and 2025. By 2026, this trend has pushed local operators to improve safety standards, training, and logistics.
In my experience, one of the biggest surprises for foreign divers is how accessible and beginner-friendly some Chinese dive spots are. The island of Hainan (Sanya + Wuzhizhou) has dozens of licensed operators, English-speaking instructors, and clear shallow reefs ideal for first-time divers.
China’s diving scene caters to four primary diver types:
- Beginners (shallow reefs & courses)
- Advanced recreational divers (offshore reefs & deep sites)
- Macro photographers (volcanic underwater terrain & muck sites)
- Technical divers (wrecks, thermoclines, deep cold-water)
Best Scuba Diving Locations in China (Top 7 Sites)
Below are the definitive best places for scuba diving in China as of 2026, evaluated for:
- Visibility
- Marine life diversity
- Water temperature
- Difficulty level
- Access & logistics
- Unique diving features
1. Sanya, Hainan Island — Best for Beginners & Warm-Water Reef Diving
Sanya is China’s most famous tropical diving hub. Located at the southern tip of Hainan Island, it offers warm water year-round, coral gardens, and accessible dive centers—perfect for training and casual reef dives.
Why Sanya Stands Out
- Visibility: 10–25m
- Water temperature: 22–29°C
- Best for: Beginners, Open Water courses, underwater photography
- Marine life: hard corals, butterflyfish, parrotfish, nudibranchs, damselfish
Popular Dive Sites in Sanya
a) Dadonghai Bay
Beginner-friendly shallow reef dives with abundant small fish. Ideal for Discover Scuba Diving and underwater photos.
b) Xiaodonghai Marine Park
Marine protected zone with healthier corals and higher fish density.
c) Yalong Bay
Long sandy bay with several offshore coral sites; moderate visibility.
Who Should Dive Here
- First-time divers

2. Wuzhizhou Island — Clear Water & Coral Gardens
Wuzhizhou Island sits off the coast of Sanya and offers better water clarity and healthier corals than most mainland-accessible spots.
Key Highlights
- Visibility: 15–30m
- Water temperature: 23–29°C
- Difficulty: Beginner to Intermediate
- Marine life: clownfish, groupers, sea urchins, starfish, moray eels
Top Dive Spots Around Wuzhizhou
- Coral Garden Reef
- Shark Bay (no sharks, just a name)
- North Wall (deeper slope, intermediate)
In my experience, Wuzhizhou offers some of the best beginner dive photos thanks to calm water and colorful coral heads close to the surface.
3. Xisha (Paracel) Islands — Best for Pristine Offshore Reefs (Advanced Divers)
The Paracel Islands (Xisha) in the South China Sea are one of China’s most biodiverse marine environments. They are remote, lightly fished, and difficult to access, making them ideal for advanced divers seeking untouched reefs.
What Makes Xisha Exceptional
- Visibility: 20–40m
- Water temperature: 24–30°C
- Difficulty: Advanced
- Dive style: Expedition cruises
Marine Life You Can Expect

- Seasonal approval
If you’re an advanced diver searching for the best scuba diving in China, the Paracels are unmatched for clarity and biomass.
4. Weizhou Island — Volcanic Reefs & Macro Life
Located in the Beibu Gulf (Guangxi Province), Weizhou Island features volcanic geology that creates unique underwater topography, caves, and macro photography zones.
Why Weizhou is Special

Hong Kong might surprise many divers. Despite urban surroundings, it offers wreck dives, conservation zones, coral communities, and marine parks.
What Makes Hong Kong Interesting
- Visibility: 5–12m

- Best for: Wreck diving, macro, conservation
- Difficulty: Beginner–Advanced
Notable Dive Areas

Quick Overview
- Visibility: 8–20m

Nan’ao is expected to continue growing in popularity through 2026 as more dive shops open and eco-tourism ramps up.
