Spent 1 day/night here with 20’ trailer. Most sites are for tents, the ones big enough for trailers won’t handle much larger than 30’ lengths. We arrived @ 11:00 we found campground almost full with reserved signs on most empty sites, but lots of the sites did have tents on them with only a handful of trailers. Sites are self registration, but I think you can reserve Thur Parks Canada - we just pulled in & picked an empty site. Wash rooms were clean with only cold running water and no electric power - make sure you have a flashlight if you are going to use them after dark. Their is no cell/phone service once you leave the TransCanada hwy & head south on hwy 93 until you reach Radium Hot Springs (about 90km south).
