Ditch the flip-flops for the limestone scramble to the summit—it’s slippery, vertical, and frankly sketchy. You get a raw, elite view of the Lan Ha Bay islands, but the macaques are professional pickpockets. Zip your phone and snacks deep inside your bag or lose them in seconds. Spend 75 minutes max, snag your ridge-line photo, and retreat to the beach bar. Keep a safe distance from the monkeys; they’re only cute until they bite.
Reaching this limestone outcrop requires navigating the jagged rocks along the eastern edge of the bay. You are essentially climbing a vertical wall of sharp, weathered stone that demands proper footwear and a complete disregard for comfort. It earns its reputation as a difficult scramble, but the reward is a clear perspective of the scattered islets and the deep blue water channels separating them. Most people underestimate the sheer steepness of the terrain, resulting in slow lines on the narrow path. Pack light, leave your valuables behind, and prepare to sweat before you even reach the higher ridge-line lookout point. Accessing this site typically requires a boat transfer from the main harbor area of Cat Ba town. Once you arrive at the beach, skip the crowded main swimming zone and head directly toward the trailhead marked near the western cliff base. Spend no more than ninety minutes here, as the lack of shade and intense humidity make the mid-day sun exhausting. Carry at least one liter of water per person, as there is no reliable source for hydration on the ascent. Secure your dry bag and avoid bringing loose plastic items that the resident macaques can easily grab from your hands. Serious hikers often mistake the initial sandy area for the actual route, but the real path starts just past the overgrown shrubs near the rocky base. If you want a better angle, ignore the first crowded landing and scramble toward the further, less populated ridges where the foliage is less dense. Afterward, avoid the overpriced stalls on the beach and instead return to the docks to find local seafood vendors along the street that serves the primary fishing fleet, where the quality is higher and prices reflect reality rather than tourism premiums. Centuries of tidal erosion have carved this island into a vertical fortress, making it a natural navigation point for historical fishing fleets in the gulf. Today, the macaques occupy the lower canopy, creating a volatile environment where they act as aggressive scavengers against visitors. The island remains entirely raw with zero infrastructure, forcing a self-reliant approach for anyone daring to scale the jagged summit during the drier winter months.
Charter a local fishing boat from the main harbor in Cat Ba town to reach the island directly. Negotiate the price for a round trip beforehand to ensure the captain waits for your return.
The terrain consists of sharp, vertical limestone rocks that require using your hands for balance throughout the ascent. It is physically taxing and dangerous for young children or anyone lacking significant mobility and grip.
Early mornings are significantly better for climbing before the daily tour boats arrive around mid-morning. Fewer humans mean the macaques are less likely to swarm visitors looking for handouts or stealing loose items.
There is virtually no reliable infrastructure on the island, including restrooms or clean drinking water. Bring everything you need from the mainland, as the temporary beach stalls often provide limited and overpriced supplies.
Most boat charters allow you to combine this stop with a visit to the floating fishing villages or kayaking near the darker caves. Coordinate your route in advance to maximize your time on water.
