Meet Monmouth Canyon, the more flamboyent sister adjacent to Box Canyon. While Box Canyon features narrow slots lined with polished granite walls, Monmouth showcases big 200ft multi-tier drops with infiniti pools that look out to the towering granite cliffs that surround the city of Squamish. But even before the spectacular views show up, there's a 20 ft nearly vertical slide into a narrow passage that defies the voice in your head telling you that it looks...looks like it ought to be a rappel instead. Assuming you've check the water levels are safe, slide! and let the fun begin.

Even during late Summer, the water is still cold as the source is glacier melt so bring a thick wetsuit (or appropriate layers of neoprene).


Getting to Monmouth canyon requires crossing the Squamish river. For small groups, consider renting a canoe at the Squamish Adventure Center. It will fit 3 people including gear. Canoes must be returned at the end of the day so be sure to know when the Adventure Center closes. Depending on the season and time of day, the mosquitos are particularly vicious near the river banks. Some may dawn on a wetsuit to prevent mosquito bites but it is advisable to change into your wetsuit at the drop-in point. The hike in is steep but on a well-maintained trail.

When you get in the proximity of the canyon, after crossing the powerlines, make sure you take the trail that goes Left. The Right branch takes to a promotory with a nice view but then dies out.


The descent is described in great detail in the Beta Sites listed below.

  • Exit

    There are several options to exit after the famous Keyhole rappel in case members of the group or cold, tired, or nightfall is approaching. After the Keyhole rappel, there are 3-4 more rappels before reaching the creek bottom. It can be done within 1.5 hrs with an experienced team.

    If you are renting a canoe from the Squamish Adventure Center, be aware of when you need to return the canoe. If possible, arrange for returning the canoe after hours.
