A Biah Hill, a.k.a Hamburger Hill, or Hill 937 is one of two historical destinations in the A Luoi highlands. The higher you climb towards the top of the hill, the narrower and more desolate the road becomes. Yet, this place still has a strange attraction for tourists, especially veterans from both within and outside the country. Many elderly visitors have to cut trees to make walking sticks, conquering more than 850 steps over 1.5km long to reach the summit.
