The Alta Green Lost 15k is a fantastic 15 kilometre(9.3 mile) trail run that takes you past three of Whistler's wonderful lakes and several gorgeous parks.  Almost entirely on the wide, paved, two lane Valley Trail, this run is constantly changing as you pass numerous stunning vantage points.  Easy to navigate and several gradual hills make this a relaxing and constantly interesting trail run.  If you are a fan of beautiful sunrises, this run is packed with spectacular ones.  If you like to jump in a lake in the middle of your run, you have many opportunities, including a naked plunge from the clothing optional pier on Lost Lake!

The Fitzsimmons 9k is a 9 kilometre(5.6 mile) running route through tranquil forests along the beautiful Fitzsimmons Creek and the scenic forest around Lost Lake.  There are plenty of nice viewpoints along the main trail as well as quite a few short trails that lead to several access points to the lake, some with great places to sit and relax in the sun and take in the view.  Lost Lake has a very popular beach at one end and in the height of summer can get busy as it is the most convenient beach from Whistler Village.  There are several swimming platforms out in the lake as well as a wonderful and huge pier along the right hand side of the lake.

The Lost Lake 6k is a nice 6 kilometre(3.7 mile) running route that takes you from Whistler Village out and around Lost Lake.  Lost Lake, along with the Whistler Golf Course 5k trail run are two of the most convenient and scenic trail runs adjacent to Whistler Village.  Both can be started in Whistler Village and both have almost constant views and easy to follow routes.  Depending on where you are in the Village you can access the Lost Lake Park via many different directions, however the Fitzsimmons Trail between Lot 1 and Lot 2 is possibly the nicest.

Lost Lake is a tranquil and secluded lake that hides in the forest extending from Whistler Village.  Just a 20 minute, leisurely walk or 5 minute bike ride along the well signed Valley Trail will lead you to this beautiful little lake.  The wide and paved Valley Trail turns into a wide and gravel trail as you enter Lost Lake Park and.  Trails circle the lake and extend in all directions.
