Pen Islet (Hòn Bút)
Pen Islet, affectionately known by fishermen and travelers as the Leaning Tower Islet, is a mesmerizing destination nestled between Ha Long Bay and Lan Ha Bay, near Cat Ba Island within the Ha Long Bay – Cat Ba Archipelago UNESCO World Heritage site. Viewed from afar, this remarkable islet resembles a colossal fountain pen rising majestically from the emerald waves, or evokes the iconic Leaning Tower of Pisa in Italy. Standing approximately 30 meters above sea level, it has been sculpted over millions of years by the relentless erosion of ocean tides, creating a striking form with an undercut base resembling a giant jaw. Locals also regard Pen Islet as the “Monument of Wisdom” of the Mother Dragon, symbolizing creativity and enduring resilience in the heart of the sea.
Positioned along the scenic cruising route from Toad Islet to the Ba Trai Dao (Three Peaches) beaches, Pen Islet is located about a 30-minute boat ride from Toad Islet. It is exclusively accessible via watercraft, allowing guests to soak in the breathtaking scenery of crystalline turquoise waters and the magnificent limestone karst towers of Lan Ha Bay. Nearby, discerning travelers can also visit Turtle Islet, Clog Islet (Hòn Guốc), Luon Cave, or an immaculate secluded beach, curating a truly enchanting voyage of discovery. Beyond its picturesque allure, Pen Islet is an idyllic haven for adventure enthusiasts seeking thrills such as Deep Water Soloing (DWS) or traditional rock climbing. Its sheer vertical cliffs—particularly on the southeastern side, featuring accessible starting points and ideal drop zones—offer an exhilarating cliff-jumping experience directly into the pristine sea.
Presently, the base of Pen Islet faces significant erosion from sea waves, posing potential structural risks for the future. Recognizing the invaluable geological significance of this natural wonder, the authorities of Cat Hai district have partnered with Japanese specialists to survey, evaluate, and formulate comprehensive conservation strategies to preserve Pen Islet for generations to come. While not as internationally renowned as the Fighting Cocks Islet or celebrated as the primary symbol of Lan Ha Bay, Pen Islet exudes an exclusive charm defined by its untouched pristine beauty, exceptional geological heritage, and profound cultural resonance. It stands as the ultimate retreat for those seeking to uncover an extraordinary facet of the Ha Long – Lan Ha Bay expanse, far away from the frequented tourist trails. Plan your journey today to experience Pen Islet – a hidden jewel of the open sea, where nature and humanity blend into a masterpiece of tranquility!
