Yen Island (Hon Noi)
Yen Island, officially known as Hon Noi (Đảo Yến - Hòn Nội), is one of Khanh Hoa Province's most extraordinary natural attractions. Located within Nha Trang Bay, the island is famous for its unique double beach, where two stretches of white sand meet between turquoise waters on both sides. It is also one of Vietnam's most important swiftlet nesting sites, producing the country's highly prized bird's nests.
Because Hon Noi is managed as a protected bird sanctuary, visitor numbers are limited and access is only possible through authorized tours. The island's pristine beaches, crystal-clear water, dramatic limestone cliffs, and spectacular panoramic viewpoints make it one of the most memorable day trips from Nha Trang.

Climb to the Viewpoint
A short staircase leads to the island's highest viewpoint, offering breathtaking panoramic views of the double beach, surrounding islands, and the emerald waters of Nha Trang Bay.
Swim and Snorkel
The island's calm, clear waters are ideal for swimming and snorkeling. Coral reefs and colorful tropical fish can often be seen close to shore during good weather.
Learn About Bird's Nest Harvesting
Hon Noi is home to thousands of edible-nest swiftlets. Visitors can learn about the traditional harvesting process, which has been practiced for centuries while carefully protecting the birds and their nesting habitat.
Relax on the Beach
With limited visitor numbers and protected surroundings, Hon Noi offers a peaceful atmosphere rarely found at more accessible beaches around Nha Trang.
Nature and Conservation
Hon Noi is part of a protected island ecosystem managed to conserve both its marine environment and swiftlet colonies. The limestone cliffs provide ideal nesting sites for edible-nest swiftlets, whose nests have long been considered one of Vietnam's most valuable natural products.
The surrounding waters are home to healthy coral reefs, diverse marine life, and exceptionally clear seas. Strict visitor management helps preserve the island's fragile ecosystem while allowing sustainable tourism.
Best Time To Visit
The best time to visit is from March to September, when calm seas and sunny weather provide ideal conditions for boat trips, swimming, and photography. Tours may be suspended during periods of rough seas or unfavorable weather.
How To Get There
Hon Noi can only be visited through authorized boat tours departing from Nha Trang. Independent access is not permitted because the island is a protected bird sanctuary managed by the local bird's nest conservation authority. Advance booking is recommended, especially during the peak travel season.
