Halong Bay is a UNESCO World Heritage natural wonder, renowned for thousands of magnificent islands and islets of various breathtaking shapes that form a living traditional ink painting. Amidst this vast expanse of emerald waters lies a remarkably diminutive yet captivating islet that commands travelers’ attention for its exceptionally distinctive silhouette – Thumb Islet (Hon Ngon Tay). Rising from the azure waves like a colossal human thumb, Thumb Islet creates a striking focal point against the majestic panorama of Halong Bay. Join Halong & Lan Ha Bay Cruise Tours as we explore this extraordinary masterpiece of nature!

The Location of Thumb Islet

Thumb Islet (also affectionately known as South Salt Islet) is a pristine geological formation situated along Sightseeing Route No. 2, en route to the iconic Titov Island – one of Halong Bay’s premier destinations (pictured below). Nestled quietly amongst majestic limestone karsts, Thumb Islet lies approximately 8 kilometers from Tuan Chau International Passenger Port and 9.2 kilometers from Halong International Cruise Port.

Much like the majority of magnificent formations throughout Halong Bay, Thumb Islet is composed entirely of ancient limestone. Through millions of years of geological metamorphosis, the persistent sculpting of seawater, wind, and rain has exquisitely eroded the rock to fashion this unique contour. Layers of limestone strata lie stacked one upon another, revealing intricate textures and natural mineral veins that impart an exceptionally distinct elegance to Thumb Islet.

True to its name, Thumb Islet resembles a colossal human thumb reaching resolutely toward the sky. The rounded “tip” and the elegantly tapered “shaft” merge harmoniously to create a striking, monolithic structure standing at an impressive height of approximately 40 meters.

While most islands in Halong Bay boast diverse, multifaceted silhouettes, Thumb Islet stands out for its deceptively simple yet profoundly striking form. This remarkable uniqueness has transformed the islet into a beloved, must-visit check-in sanctuary for discerning travelers exploring the bay.
