Tips from the Community
Located 12 miles from the main section of Bandelier National Monument on State Highway 4, the Tsankawi section offers a 1.5-mile walk along a mesa, showcasing cavates, petroglyphs, and an Ancestral Pueblo village. The trail is sometimes narrow in places, requires some scrambling in addition to climbing several ~12 foot ladders, and is quite exposed to the elements so it should be avoided during thunderstorms and inclement weather. In winter, the path may be slippery and icy. Tsankawi also can be a little challenging to locate, in large part because it signs on Highway 4. From Santa Fe, turn from State Highway 502 to 4, finding Tsankawi less than 1/4 mile on the left. Coming from Bandelier, it's easier to locate, with the gravel parking lot on the right past the 3rd stoplight. Here is a link to a great virtual tour of the site by the NPS: nps.gov/band/learn/photosmultimedia/tt-vt-intro.htm
