Mount Sproatt Whistler Area Hiking Trails
Mount Sproatt, or as it is known locally as simply "Sproatt", is one of the many towering mountain peaks visible from Whistler Village. It towers far above Alta Lake, across from Whistler and Blackcomb Mountains. As you walk through Whistler Village you will notice it looming large, above and beyond Alta Lake.
Though a hive of snowmobile and ski/riding activity in the winter and spring, Sproatt is infrequently hiked in the summer. There are about four ways to hike to the summit of Sproatt and unfortunately none are very easy. Possibly the best and most convenient route from Whistler is by hiking up along Sproatt Creek from the Flank Trail. This is an entirely unmarked, bushwhacking route, however, as you are following the coarse of Sproatt Creek it is easy to follow. It is very steep at times and not very enjoyable unless you are hoping for a challenge. It is, however, very direct and comparatively short.
An excellent place to start this hike is at the trailhead to Beaver Pass near Alta Lake. This is a well known bike trail in the area and connects to another bike route called Cheap Thrills which connects to the Flank Trail which leads to Sproatt Creek. It all sounds confusing, but the route is actually fairly easy to find. Beaver Pass is a cute trail, Cheap Thrills is a steep and varied trail with amazing views and a great array of biking bridges and ramps along the route.
The Flank Trail is very scenic with tremendous views down and across the valley to Whistler. Then of course when you reach Sproatt Creek, the real challenge begins. The route is obviously very overgrown and at times very steep. You simply follow Sproatt Creek on its right side, keeping within 300 metres or so until you reach the alpine, at which point you can see where you are going. At 1400 metres you will come to an amazingly lush, green valley. Unfortunately the foliage is chest deep at this point, but bear left and you will pass through it in about 15 minutes and hit the alpine at 1600 metres. From this point you will see Sproatt directly to your right.
The route from the Beaver Pass trailhead to Sproatt Mountain is 6.5k one way and because of the difficult, steep terrain will likely take at least 2.5 hours up but only 1.5 hours down. Once in the alpine around Sproatt Mountain, accessing Rainbow Lake is relatively easy and in fact a through hiking route can be achieved by exiting via the Rainbow Trail. You do have to get back to your car via the Flank Trail from the Rainbow Trail then Cheap Thrills again and Beaver Pass. This is an amazing option, as you don't have to return via the difficult scrambling terrain you used to get up to Sproatt, and you get to see the beautiful scenery of Rainbow Lake and the Rainbow Trail exiting from it. It does, however, make the return journey 15k instead of 6.5k.
Access to Mt Sproatt from the Beaver Pass Trail
From Whistler Village zero your odometer and drive south on the Sea to Sky Highway. Continue past the lights at Creekside and take the next right at Alta Lake Road (at 5.2k) and follow Alta Lake Road for 1.4k, turn left on Stonebridge Drive and keep your eye out to your left for the trailhead for Beaver Pass, about 1k from this turn.
Park at the trailhead and hike for .8k until you see an unmarked trail to your right. This is Cheap Thrills, a bike trail. You will know you are on the correct trail when you see elaborate bike ramps along the trail.
Follow Cheap Thrills for 1.4k until you come to the Flank Trail, turn left and continue 1.9k until you reach the obvious and well marked Sproatt Creek. Do not Cross the Sproatt Creek Bridge. Instead back up 20 metres and you will see a large, stove sized boulder on your right, just off the trail.
Start here, bushwhacking uphill parallel to Sproatt Creek, keeping within 300 metres until you reach the alpine, where you will be able to see where you are going. It is only 2k from here to the alpine and 2.5k from here to Sproatt's summit but it seems a lot longer. Expect to take 1.5 hours to reach the alpine from this Flank Trail junction.
