There are numerous campgrounds along Hwy 93, and there's also the NumTiJah Lodge, right by Bow Lake. I'll warn you now, it's quite expensive.

They have some absolutely stunning artwork in the dining room :rolleyes:

Regardless of where you stay, you'll have to make reservations ahead of time. Check out http://www.num-ti-jah.com/, and http://www.pc.gc.ca/pn-np/ab/jasper/visit/index_e.asp for more information.
