Mystery Lake

Mystery Lake on Mount Seymour in North Vancouver is one of those quick-hit hikes that still feels like a proper mountain trip. The trail is only about 2.3 km out and back with 141 m of gain, so you’ll be at the lake in under an hour, even with breaks. It’s a popular spot on summer weekends thanks to the swimmable alpine lake and easy access from the Mount Seymour parking lot.

The hike to Mystery Lake is short but punchy. The route climbs steadily over rocks and exposed roots, with a couple of steeper, scrambly sections that keep it interesting but still doable for active kids and newer hikers. On clear days, you can catch a solid view back toward the city partway up, then finish at a small rocky basin lake that’s great for a dip, salamander spotting, and short swims out to the rock islands.

Recent hikers report the trail is well marked and easy to follow, but it can be muddy, slick, and even icy in shoulder season, so proper hiking shoes are a smart call. In summer, the main complaints are bugs: mosquitoes, horseflies, and general buzzing chaos around the lake, so bring bug spray and maybe a light layer. Expect some algae on the water later in the season, but it’s still swimmable and refreshing, especially on hot 30° days. The lake can stay frozen or snowy well into spring, and fog can completely hide the views, so check conditions, carry bear spray, and aim for May to October for the most reliable experience on the Mystery Lake trail in North Vancouver.
