This is the definition of low-effort, high-reward. Start at the Pyramid Island bridge trailhead, cross the short wooden bridge, and follow the compacted path around the tiny island. The route returns along the same bridge, with lake-and-mountain views throughout and especially good reflection photos when the water is calm.
Plan on roughly 0.29 miles (0.47 km) total for the bridge, island connector, shoreline loop, and return over the bridge. That is about 10 minutes of easy walking (0.17 hours), with extra time worthwhile for photos, benches, and the historic shelter. The route is essentially flat and family-friendly rather than a workout.
On the island you’ll find a rustic 1933 log shelter recognized as a Federal Heritage Building, benches, and views toward Pyramid Mountain. The bridge and shoreline make strong photo foregrounds, while birds are common around the lake and deer may be seen nearby. If you want a longer outing, use the separate Pyramid Lake Overlook Loop rather than extending this short island route.
The bridge and island path are mostly flat and reached from a designated trailhead parking area. Parks Canada identifies one accessible paved stall at the trailhead, but it has no side access aisle; compacted gravel, roots, and small uneven sections mean the loop should not be assumed to be fully wheelchair accessible. Winter ice can make the bridge and path slick, so use traction. Parking is limited, and the short route can bottleneck around the bridge and shelter at busy times.
