A big thank you to those who secured the final 600 meters to the summit using stairs and ropes! The panoramic view of the mountains, Da Lat, and (unfortunately) the sea of plastic greenhouses makes the climb to 2167 meters well worth the effort!

The trail leads to the Five Lakes. Crystal-clear water, small waterfalls, and the opportunity to swim make the hike a beautiful nature experience. It crosses bridges, steps, and narrow paths, some of which are secured with ropes. Very slippery when wet.
