At the top, you will be rewarded with a very scenic, aerial view of the city and the Mekong river. It is a very beautiful sight given the mountainous backdrop. It is also a popular destination to appreciate the sunset, so it will likely be very crowded during sunset time.
Best time to climb is likely during the early morning hours, or just before sunset time. It may be too scorching hot for a comfortable climb in the middle of the day. There’s also an entrance fee of 20.000 kip near the top of the climb.
