Hepeng Cove (Butterfly Valley) (蝴蝶谷, Húdiégǔ)
Hepeng Cove (蝴蝶谷) is a secluded beach area 30 kilometers south of Sanya, named for the butterfly sanctuary in the forested hills behind the beach. The cove is smaller and less developed than Sanya's main beaches, with crystal-clear water, colorful coral reefs close to shore, and a small pocket of white sand. The butterfly sanctuary (蝴蝶泉) in the hills behind the beach houses dozens of tropical butterfly species in a netted garden environment. It is the best beach near Sanya for snorkeling due to the proximity of the reef to the shore.

What to expect
The butterfly sanctuary (蝴蝶泉) is located in the forested hills behind the beach, a 10-minute walk up a stone path through tropical vegetation. The sanctuary is a net-covered garden approximately 1,000 square meters in size, planted with flowering plants that attract dozens of tropical butterfly species. Visitors can walk through the garden and observe the butterflies up close. The sanctuary was established to protect the local butterfly population and to provide an educational experience — it is one of the few places in Hainan where butterflies can be reliably observed.
How to get there
A DiDi or private car is required. From central Sanya, the cove is approximately 30 km (45 minutes by DiDi, ¥80–120 one way). The cove is not on the main bus routes. It is best combined with a day-trip itinerary that includes other attractions in southern Hainan — Yalong Bay is 30 km away, Tianya Haijiao is 25 km away.
Best photo spots
- The underwater shot of coral and tropical fish from 30 meters off the shore — the cove's signature experience
- The view from the butterfly sanctuary hilltop — the cove and the South China Sea
- The small pocket beach at low tide — a perfect crescent of white sand between the headlands
- The colorful butterfly species in the net garden
Tips
- Bring your own snorkeling mask if possible — rental masks are available but of variable quality
- Go early morning (8:30 AM when the park opens) for the clearest water and fewest visitors
- Combine with a stop at Yalong Bay or Tianya Haijiao on the same day — they are all within 30 km of each other
- Bring water and snacks — the facilities at the cove are basic
- Wear water shoes — there are some rocks and coral on the seabed that can be sharp
Scams to avoid
- No significant scams at this relatively low-key site. Be aware of informal "snorkeling guide" services — the reef is close enough to shore that a guide is not necessary if you are a competent swimmer
Frequently asked questions
Is Hepeng Cove worth visiting?
Yes — if you want the best snorkeling near Sanya and don't want the crowds of the main beaches. The reef is accessible 30 meters from shore, making it ideal for snorkelers of all levels. The butterfly sanctuary adds a second attraction. Budget a half-day.
Is the water at Hepeng Cove clearer than at Yalong Bay?
Yes — the cove is more sheltered and the reef is closer to shore, meaning less sediment stirred up by swimmers. Underwater visibility can reach 8–10 meters in the early morning, which is significantly better than at Yalong Bay.
Is Hepeng Cove wheelchair accessible?
No. The path to the beach involves some uneven terrain and the beach itself is sand. The butterfly sanctuary requires a 10-minute walk up a stone path. Neither is accessible for wheelchair users.
Can I see butterflies at any time?
The butterfly sanctuary is best visited in the morning (9:00–11:00) when butterflies are most active. Butterflies are less active in the afternoon heat. The sanctuary is a net-covered garden — butterflies are present year-round but species vary by season.
Do I need to be a strong swimmer to snorkel here?
No — the reef begins 30 meters from shore in chest-deep water, so even non-swimmers can get close to the coral by wading. However, a life jacket is recommended for those who are not confident in the water.
