The trail is demanding, with 1000m of elevation gain, but is well-maintained, making it accessible to moderately experienced hikers. From the Rubble Creek trailhead, over 20 switchbacks take you up 770m to a major intersection. The right fork to Garibaldi Lake is described here, but taking the left fork would allow for a loop via Taylor Meadows.

After the turnoff, you'll be rewarded with a wide-open view of The Barrier. If it ever collapsed, water from the lake would release onto the town of Squamish with catastrophic effect2.

Once at the lake, follow the shore to the campground where there are 50 tent sites, 4 day-use shelters, and 4 pit toilets. Note that as of 2018, BC Parks requires reservations year-round for camping at both Garibaldi Lake and Taylor Meadows: http://www.env.gov.bc.ca/bcparks/explore/parkpgs/garibaldi/#Reservations.

Numerous options exist beyond here for those with the time and experience; Black Tusk and Panorama Ridge being the most well-known. Otherwise, once you have taken in the views and replenished your energy reserves, head back down the same way.
