The Con Dao Archipelago off HCMC is often associated with turquoise waters, quiet beaches, and the tranquil beauty of an island escape. Yet beyond the coastline lies another experience for travelers seeking nature and adventure: trekking Lo Voi Mountain.

Located just a few kilometers from the center of Con Son Island in the archipelago, Lo Voi Mountain rises more than 300 meters above sea level and offers sweeping views of Con Son Bay and the surrounding islets scattered across the deep-blue sea. The trek begins at the base of the mountain, where narrow trails wind through shaded forests, cool air and the echoes of birdsong filling the stillness. The route has recently been upgraded with stone-paved paths, making it accessible even to first-time trekkers. Gentle slopes and stone steps provide just enough challenge to keep the journey engaging without being overly demanding. A round trip typically takes two to three hours. One of the most striking sections is a narrow trail that traces the mountainside like a dragon’s spine. From here, trekkers are rewarded with panoramic views of Con Son Bay, where emerald waters, rolling hills, and a peaceful seaside town merge into a scene of remarkable calm. Beyond its natural beauty, Lo Voi Mountain also holds historical significance. Its name derives from the Lo Voi facility at the mountain’s base, built by the French colonial administration in 1864 to support the Con Dao prison system. Prisoners were once forced to collect coral and burn it to produce lime for construction. Today, the remaining relics stand as quiet reminders of the island’s painful past. The best time to trek Lo Voi Mountain is from March to September, when dry weather, calm seas, and clear skies create ideal conditions. Many visitors come here to watch either the sunrise or the sunset over the island. For travelers seeking a different perspective on Con Dao, Lo Voi Mountain offers more than a scenic hike. It is a place where untouched nature and layered history converge. To help preserve the landscape, visitors are encouraged to minimize plastic waste, avoid open flames, and follow conservation guidelines throughout the journey.
