One of the best things about Whistler, (in my humble doggie opinion) is that there is an abundance of dog beaches to enjoy. My favourite was Lost Lake, which is a pleasant 20 minute walk from the center of Whistler Village. Canine Cove, the off leash dog beach is part way up the east side of the lake, about a 5 minute walk on a gravel path from the visitor drop-off lot.
Lost Lake has a dock, a few yards off the dog beach, with a ramp so dogs can easily get up and down. There's also a waste bag dispenser and garbage can right at the beach so dog owners can help keep the beach clean and enjoyable. The beach has some shade during the day and there are two benches for people to sit on while they watch their furry friends swim. The lake boasts some gorgeous mountain views and while it's a popular destination with locals and tourists alike, it's surprisingly peaceful.
While we were in Whistler, Dad and I also visited Alta Lake. Alta Lake is a 10 minute drive from Whistler Village. Once you park, it's a 2.5 km walk on a paved path from the parking lot to the dog beach. The dog beach is to one side of the people's swimming area. The downfall of this lake is that there were signs warning of "swimmer's itch", so we only went there once. (Who wants to get that?!?)
There are a few more dog beaches we didn't get the chance to visit, so we'll check them out the next time we're up in Whistler.
