Introduction to Hon Noi Island
Hon Noi Island, also known as Yen Island, is a hidden gem located in the pristine waters of Nha Trang – Khanh Hoa Bay, about 25 kilometers from Cau Da Port. This island is famous not only for its natural beauty but also as Vietnam’s largest natural reserve of edible bird’s nests, harvested from swiftlets that live in the island’s rocky caves.
While several islands in Nha Trang Bay are home to swiftlets, Hon Noi Island has the highest concentration, making it a central hub for bird nest collection and a place of high economic and cultural value.
Beyond its swiftlets, Hon Noi Island is becoming an increasingly popular destination for eco-tourism. Its most iconic feature is the twin beach—a unique natural wonder where two sandy shores lie back-to-back, divided by a narrow strip of white sand and embraced by clear turquoise waters on both sides.
Visitors to Hon Noi Island can enjoy relaxing on the beach, snorkeling in calm waters, hiking up the island’s scenic viewpoint, and discovering the fascinating world of swiftlet conservation.
Important Note: Hon Noi Island is managed by Sanest Khanh Hoa Company. To protect the environment and manage tourism responsibly, independent travel is not allowed. All visitors must book an official guided tour to access the island.

Travel tip: As you near the island—about two-thirds into the journey—the sea becomes rougher due to fewer surrounding islands. If you are prone to motion sickness, it’s best to sit at the rear of the boat for more stability.

Ideal Time to Visit Hon Noi Island Nha Trang
The best time to visit Hon Noi Island Nha Trang is from March to September, during the spring, summer, and early autumn seasons. During these months, the weather is generally sunny, warm, and pleasant—perfect for sightseeing, swimming, and relaxing by the sea.
From May to July, the skies are especially clear, the sea is calm, and the water is cool and refreshing—ideal conditions for a beach vacation. This period is also considered peak season for visitors who want to enjoy outdoor activities and explore the unique landscapes of the island.
Additionally, March to September is the time when swiftlets return in large numbers to Hon Noi. Visitors not only get to experience the island’s natural beauty but also witness flocks of swiftlets hovering above the cliffs and nesting areas—an experience unique to Yen Island Nha Trang.
However, it’s important to avoid traveling to Hon Noi between October and December, as this is the rainy and stormy season in the region. During these months, high winds and rough seas make boat travel dangerous, and tours may be suspended for safety reasons.
Must-Visit Check-in Spots at Hon Noi Island Nha Trang
Here are some unmissable spots at Hon Noi Island Nha Trang that you should check out, brought to you by Vn Car Rentals’s!
Nha Trang Double Beach
Double Beach is undoubtedly one of the most picturesque spots on Hon Noi Island, perfect for anyone looking to capture breathtaking photos. Surrounded by two majestic mountains, this beach is divided by a natural strip of sand and coral, which has been shaped over time by the sea waves.
From above, the sand and clear blue waters create an incredibly poetic and unique sight. The combination of smooth sand and crystal-clear waters makes this beach a true natural masterpiece, often likened to a stunning painting created by Mother Nature.
The beach is divided into two distinct sections:
The right side is a short beach with shallow waters, perfect for swimming or enjoying water activities.
The left side is a long beach with a deeper, blue-colored sea.
What makes Double Beach even more fascinating is its unique color contrast. The two beaches, despite being close to each other, feature different water colors: the right beach has a greenish hue, while the left side is blue. Additionally, due to the effect of sea currents, visitors can experience a hot side and a cold side of the beach, making it a special spot to relax and explore.
Bird’s Nest Caves at Hon Noi Nha Trang
One of the most fascinating experiences you can have while visiting Hon Noi Island Nha Trang is exploring the deep bird’s nest caves. If you’re an adventure lover or someone interested in local culture, this journey is definitely worth your time.
As you enter the caves, you’ll be amazed by the dense nests hanging from the rocky walls. Swiftlet farming in Nha Trang is a long-standing tradition, and these caves are central to the industry. From April to September, swiftlets build their nests by secreting a fluid from their mouths, which hardens into grayish-white nests attached to the cave walls.
During the harvest season, locals use ropes or bamboo ladders to carefully climb the cave walls and collect the nests. These nests are a valuable commodity in Nha Trang, as they are a key ingredient in many traditional specialties such as bird’s nest soup.
Visiting the bird’s nest caves not only allows you to witness this unique practice up close but also gives you a deeper appreciation for the local culture and craftsmanship tied to Hon Noi Island.
Du Ha Mountain Peak
For adventure enthusiasts, climbing Du Ha Mountain is an exciting experience you shouldn’t miss. The climb consists of 220 steps that take you up to a height of 90 meters. At the summit, you’ll find a small tower that houses a Buddha statue, making it a serene and spiritual stop along your journey. Respectful attire is recommended when visiting this sacred site.
At the top of Du Ha Mountain, there is also a national coordinate landmark, adding a unique touch to your visit. The panoramic view from this high vantage point is simply breathtaking. From here, you can gaze out over Hon Noi Nha Trang in all its glory — the emerald-green double beach, the boats clustered near the jetty, and the surrounding mountains blending into the sea beneath the expansive sky.
If you’re a photography enthusiast, this is the perfect spot to capture stunning photos of the island’s natural beauty.
What to Eat During Your Hon Noi Island
Located in the heart of the sea, Hon Noi Island Nha Trang is a paradise for seafood lovers. Thanks to its rich marine ecosystem, the island offers visitors a chance to enjoy fresh and flavorful seafood dishes prepared in authentic Central Vietnamese style.
When you book a tour through Sanest Khanh Hoa, your visit includes a delicious lunch featuring local seafood specialties. The menu typically includes:
Fresh squid, lightly fried and served with spicy ginger dipping sauce
Scallops grilled with butter, offering a fragrant, creamy taste
Grilled snails and shellfish, topped with rich green onion oil
Crispy shrimp, bursting with savory coastal flavor
The highlight: sour raft fish soup, a traditional Central Vietnamese dish with a perfect balance of sour and sweet flavors
The dishes are prepared in a simple, traditional way to preserve the natural sweetness and freshness of the seafood. While the exact menu may vary from day to day, every meal captures the essence of Nha Trang’s coastal cuisine.
If you enjoy snacking between meals, it’s a good idea to bring along your own light snacks or favorite treats, as food options outside the tour package are limited on the island.
