Cirque or Cirque Lake Glossary of Hiking Terms
Cirque: a glacier-carved bowl or amphitheatre in the mountains. To form, the glacier must be a combination of size, a certain slope and more unexpectedly, a certain angle away from the sun. In the northern hemisphere, this means the glacier must be on the northeast slope of the mountain, away from the suns rays and the prevailing winds. Thick snow, protected in this way, grows thicker into glacial ice, then a process of freeze-thaw called nivation, chews at the lower rocks, hollowing out a deep basin. Eventually a magnificently circular lake is formed with steep sloping sides all around. Cirque Lake in Whistler is a wonderful example of a cirque lake.
Cirque Lake in Whistler is accessible by a short canoe route across Callaghan Lake, then a very steep and challenging two kilometre hike. The trailhead to Cirque Lake is found at the far end of Callaghan Lake. The Callaghan Lake turnoff is 20km south of Whistler Village. From Whistler drive 20km towards Vancouver, then turn right at the sign for Whistler Olympic Park. Drive up the beautiful, winding road for about 8 minutes. The sign for Callaghan Lake will be just before Whistler Olympic Park, you will turn left, cross a bridge and drive a bumpy logging road for 8km.
Cirque Lake is one of the most beautiful lakes to visit in the Whistler area. The wild and hostile environment contained in a cirque valley create a staggeringly enchanting world high above Callaghan Lake. It is very remote feeling despite the short 2 kilometre hike to reach it. Getting to the trailhead requires paddling the length of Callaghan Lake to find the hardly visible beginning of the trail.
To reach the very hidden trailhead to Cirque Lake, paddle your canoe towards the waterfall far off in the distance. Not until you are only 50 metres from the shore, nearest the sound of the now hidden waterfall, you will see a small clearing jutting out from the shore, this is the trailhead, despite it not looking like one. Pull your canoe up here and drag into the bushes. Only a few metres into shore you will notice an obvious trail. Callaghan Lake is a destination on its own. A beautiful alpine lake, well above the busy world around Whistler Village. Bring a canoe and paddle across the lake to find amazing rock cliffs and cute little islands.
Callaghan Lake Provincial Park is a relatively untouched wilderness of rugged mountainous terrain. The valley walls were formed by relatively recent glaciation. Evidence of this can be seen in the considerable glacial till and slide materials visible across the lake. Around the lake you will see talus slopes, flat rock benches, cirques, hanging valleys, tarns, waterfalls and upland plateaus with bogs. The wildlife that reside in the area include bobcats, cougars, coyotes, minks, wolverines, wolves, bears, deer, mountain goats and occasionally moose and grizzly bears.
The hiking trails are minimal here due to the steepness and deep forest surrounding the lake. From the main parking area some short trails extend in either direction. The trails to the left go for just a few dozen metres before ending at the lake and river outflow. The trail in the other direction(right if facing the lake from the parking area), takes you around the bottom of the lake and quickly fades into a bit of a bushwhacking route. You can, if you are determined, follow this route around the right side of the lake to its top end and connect to the Cirque Lake trail. The bushwhacking is not that bad and you can stay within sight of the lake the entire time.
