How to get to Cham island

Cham Islands is a cluster of islands located off the coast of Quang Nam Province, about 15–20 km east of Hoi An Ancient Town. It is a popular destination thanks to its unspoiled beauty, crystal-clear waters, and rich marine ecosystem.

The area has been recognized as a World Biosphere Reserve by UNESCO, featuring coral reefs, seagrass beds, and a wide range of rare marine species. With such ideal natural conditions, it has become one of the top spots for snorkeling and diving in Central Vietnam.

To start your cham island snorkeling trip, travelers usually head to Cua Dai Port (Hoi An), where you can choose between two main transportation options:

Speedboat (cano): This is the most popular option, taking only about 15–20 minutes to reach the island. It’s fast, convenient, and ideal for most day-trip visitors.
Wooden boat (slow boat): This option takes longer, 1.5 -2 hours, and is better suited for those who want a more traditional sea travel experience or are looking to save money.

In terms of cost, a full-package tour from Hoi An or Da Nang typically ranges from 450,000 to 800,000 VND per person, including speedboat transfer, entrance fees, lunch, and snorkeling activities. If you travel independently, you can purchase a speedboat ticket separately at a lower cost, but you will need to arrange other services on your own. From Da Nang, you can travel to Hoi An by taxi or motorbike (around 40–50 minutes), then continue your journey to the islands from there.

Snorkeling vs other ocean activities in Cham island

When exploring the ocean at Cham Islands, snorkeling is the most popular choice thanks to its simplicity and accessibility. However, there are also scuba diving and sea walking, each offering a different level of experience, from basic to more immersive. Understanding these differences will help you choose the activity that best matches your preferences and comfort level.

Snorkeling – Easy, beginner-friendly, and still impressive

Snorkeling is the most accessible way to explore the ocean, making it perfect for first-time visitors or anyone joining a day trip. You simply float on the surface and look down at the coral reefs—no deep diving required.

Depth: around 1 – 3m
Duration: 20 – 40 minutes per session
Skill level: no swimming required (life jacket provided)
Cost: usually included in tour packages

What makes snorkeling so appealing is how easy and enjoyable it is, even for beginners. In spots like Bai Xep or Hon Nhon, coral reefs are very close to the surface, so you can clearly see vibrant colors and schools of fish without much effort. The only downside is that you’ll stay in shallow water, so you won’t get to explore deeper reefs or more complex marine environments.

Scuba Diving – A deeper, more immersive experience

If you’re looking for something more adventurous, scuba diving lets you go beneath the surface and truly experience the underwater world up close.

Depth: around 5 – 10m (for beginners with instructors)
Duration: 15 – 30 minutes
Requirements: guided by instructors, basic equipment introduction
Cost: around 800,000 – 1,500,000 VND

Compared to snorkeling, diving offers a much more immersive and detailed experience. You can swim alongside larger coral formations, explore underwater terrain, and encounter a wider variety of marine life, especially in offshore areas like Hon Dai or Hon Nhon. That said, it does require a bit more preparation, a higher budget, and some comfort with wearing diving equipment.

Sea Walking – Explore underwater without swimming

Sea walking is a great middle-ground option for those who want to go underwater but prefer not to swim or dive.

Depth: around 3 – 5m
Duration: 15 – 20 minutes
Skill level: no swimming required
Cost: around 600,000 – 1,000,000 VND

With a special helmet that supplies oxygen, you can walk on the seabed and observe marine life up close in a very relaxed way. It’s simple, safe, and ideal for non-swimmers. However, the experience usually takes place in a fixed area, so it may feel less dynamic and varied compared to scuba diving.

Best spots for snorkeling in Cham Island

Cham Islands is home to one of the richest marine ecosystems in Central Vietnam, with over 300 species of coral and a wide variety of tropical fish. Each snorkeling in cham island spot offers different conditions in terms of depth, visibility, coral density, and crowd levels. Below is a detailed breakdown of the most popular and worthwhile locations.

Hon Nhon

Hon Nhon is located off the southeastern side of the island cluster, about 10–15 minutes by speedboat from the main island (Hon Lao). This is considered one of the best snorkeling and diving spots thanks to its relatively untouched environment. The underwater terrain slopes gradually from 2–3m down to 6–8m, creating multiple ecological layers.

Here, you’ll find dense hard corals such as table and branching corals, along with colorful soft corals. Marine life is abundant, including butterflyfish, parrotfish, damselfish, and occasionally larger schools of fish further offshore. During the best season, underwater visibility can reach 15–20m.

Depth: 3 – 8m
Visibility: 15 – 20m
Current: light to moderate
Highlights: pristine coral reefs, fewer tourists

Bai Xep

Located on the southern side of Hon Lao, Bai Xep is widely regarded as the most beginner-friendly snorkeling spot. The seabed slopes gently, and coral reefs start appearing just 10–30m from the shore. With shallow water ranging from 1.5 – 3m, sunlight easily penetrates, making coral colors especially vibrant.

Coral density here is high, dominated by branching and massive corals. Small, colorful fish are easy to spot, making it an ideal “first snorkeling” experience. The water is usually calm with minimal waves.

Depth: 1.5 – 3m
Visibility: 10 – 15m
Coral distance: 10 – 30m from shore
Highlights: easy access, vibrant coral colors

Bai Ong

Bai Ong is located on the western side of the island, near the main pier and residential area. It is often the first stop in most tours. While not the richest in coral, it serves as a great introduction to snorkeling. The seabed is relatively flat, with depths of 2 – 4m.

Coral formations are scattered and typically found 30–50m from shore. Due to boat traffic, water clarity here is slightly lower compared to more remote spots.

Depth: 2 – 4m
Visibility: 8 – 12m
Coral distance: 30 – 50m from shore
Highlights: convenient location, easy access

Bai Bim

Bai Bim is a quieter, less-visited area located further from the main tourist zones. It is often included in private or more specialized tours. The underwater terrain features a mix of rocks and large coral formations, creating natural habitats for marine life.

With depths ranging from 3 – 5m, the water remains relatively stable and clear. Coral structures here are larger and healthier, with fewer signs of damage compared to busier areas.

Depth: 3 – 5m
Visibility: 10 – 15m
Terrain: rocky seabed with large coral clusters
Highlights: peaceful setting, healthy coral

Bai Chong

Bai Chong is located on the northern side of Hon Lao and is known for its scenic beach and coconut trees. It is commonly used as a lunch stop during tours. Snorkeling areas are typically farther offshore, about 40–70m from the beach, with depths of 3 – 6m.

The underwater landscape includes rocks, crevices, and coral patches, attracting a wider variety of fish, including some larger species. While coral density is moderate, biodiversity is quite high.

Depth: 3 – 6m
Visibility: 10 – 15m
Coral distance: 40 – 70m from shore
Highlights: diverse marine life, scenic surroundings

In addition to the main locations above, there are several lesser-known spots around Cham Islands that are sometimes included in extended or private tours. Areas like Bai Huong, Bai Lang, and smaller offshore islets offer decent snorkeling conditions, especially during calm weather. While these spots may not always match the coral density of Hon Nhon or Bai Xep, they provide a more local, less crowded experience and can be great alternatives if you want to explore beyond the typical snorkeling in cham island route.

When is the best time for Cham island snorkeling?

The best time for cham island snorkeling at Cham Islands is not only about good weather, but also about water clarity and coral visibility.

The ideal period runs from March to September, when the region enters the dry season. During this time, the sea is calm, waves are minimal, and sunlight is strong enough to penetrate deep underwater. As a result, visibility can reach 10 – 20 meters, creating perfect conditions for spotting coral reefs and marine life.

More specifically, April to July is considered the peak window for the best snorkeling experience. After the rainy season, sediment in the water has settled, making the sea exceptionally clear. Coral reefs appear more vibrant, colors are sharper, and fish activity is noticeably higher around the reefs. This is when you’re most likely to see healthy, colorful coral instead of dull or low-visibility conditions.

In addition, the best time of day for snorkeling is typically in the morning (8:00 AM – 11:00 AM), when sunlight is optimal and the water surface is less disturbed by boats. This small detail can significantly improve your overall experience.

On the other hand, it’s best to avoid visiting from October to February, which is the rainy and rough sea season in Central Vietnam. Strong winds and waves reduce visibility to around 5 – 8 meters or even lower after heavy rain. Even though coral is still present, it becomes much harder to see, and many snorkeling tours may be canceled due to unsafe conditions.
