There are three rooms with some of the best murals I’ve seen. The certainly are one of the best preserve Mayan art available today and probably one of the best preserve Meso-American art as well.
The sight is amazing. As in Tonina, the main pyramid lies in a hill, making it for a challenging climb. This pyramid is quite smaller then Tonina though, so you don't have to fear the climb :).
Bonampak is monopolized by the Lancandon Indians, so expect a high entry fee (they even force you to take their vehicles the last couple kilometers of the road used to access the ruins).
