The land of Binh Lieu leaves a lasting impression on visitors with mountain peaks and border milestones waiting to be conquered, among which the peak of Cao Xiem Mountain stands as the highest in Quang Ninh Province. Out of 64 boundary markers, only a few are utilized for tourism, such as markers 1300, 1302, 1305, and 1327. Among them, landmark 1305 is the most popular choice for adventurers.

Cao Xiem Peak, also known as Khau Khoang Peak or Cot Co (Flagpole), stands at 1,429m above sea level. The cold season here usually lasts from November through the end of March of the following year, which is also the peak season for trekking and cloud hunting. From the 1,429m summit, travelers can enjoy panoramic views of the vast, rolling mountains of Binh Lieu District.

The route from the foot of the mountain to the summit of Cao Xiem Mountain is over 7 km long, making it ideal for combining trekking with outdoor camping. The trail mainly follows footpaths along the mountainsides, traversing vast hills of reed grass. From Binh Lieu town center, there are 4 trekking routes to conquer Cao Xiem: via Cao Thang Village (Luc Hon Commune), Luc Ngu Village (Huc Dong Commune), Ngan Meo Village (Luc Hon Commune), and Co Nhan Village (Tinh Huc Commune).

However, the trails via Luc Ngu and Co Nhan are rarely traveled and mostly used by locals for grazing livestock. The routes via Cao Thang and Ngan Meo villages are more accessible and therefore more frequently chosen by hikers.

Reaching an altitude of around 1,000m, visitors will clearly feel the shift in temperature as the air becomes thinner. The natural landscape grows even more majestic with continuous stretches of stone "ramparts" running along the ridges.

These stone walls were originally built by the people of Luc Hon and Huc Dong to demarcate territory and prevent livestock from straying across boundaries. Legend also has it that long ago, a young couple from Huc Dong and Luc Hon communes used to secretly meet on the mountain for dates.

They were discovered by the villagers and forbidden from seeing each other; to avoid gossip, residents of both communes erected these stone barriers. These stone walls were built centuries ago, and no one knows exactly in which year.

From the base of the mountain, it usually takes about 2 hours to reach the summit of Cao Xiem. In particular, toward the end of the year, hikers along the trail can admire ancient sweetgum trees ablaze with vibrant red leaves, camellia oleifera flowers blooming in pure white, and star anise trees bearing fragrant fruit.

The trek up Cao Xiem Mountain is not overly long, but hikers should remember to hydrate and take breaks to conserve energy. At the summit, summer temperatures range around 15–19°C, while in winter they can drop below 10°C.

On clear days, the peak of Cao Xiem Mountain offers sweeping views of all of Binh Lieu District and the high mountain range bordering China. The descent is less exhausting, yet it can still cause leg fatigue for those unaccustomed to continuous exercise. Therefore, for a fulfilling trekking journey, you should exercise regularly, engage in jogging or cycling to build endurance before embarking on your mountain climb.
