“This family friendly run skirts the shoreline of Trillium Lake through wetlands, to a spectacular view of Mt. Hood.”— Kathleen Walker

After about 1000 feet, you come to a boat ramp and fishing platform. Cross the road and pick up the trail again. Skirt around an inlet of the lake. Several hundred feet later, you come to a second road boat ramp located within the campground. Bear left towards the lake and pick up the trail again as it skirts along the shoreline between the water and the campsites. After another 1000 feet, you come to an amphitheater along the shoreline.
Continue on the trail past the middle of the amphitheater and head past the last few campsites. Curve around a wet inlet on the lake. The rest of the trail will have lots of boardwalk as the trail was built in the wet meadows to take advantage of bird watching. After about one mile, you'll come to the intersection with the Trillium Bike Trail that heads towards Government Camp.
Just past this point is a boardwalk spur off the trail. At that point, you break out of the trees and can check out the views. Continue around the north end of the lake through wetlands full of frogs, salamanders, and lily pads. The trail then heads in and out of patches of trees as it starts around the far side of the lake. The trail here parallels a road on the back side of the lake. The trail heads towards the point where this road meets the dam. Continue across the dam back to your starting point. You can now go for a swim.
The trail was designed to be barrier free for strollers, wheelchairs, etc. However, no treated wood was allowed in the wetland structures to protect amphibians, making it difficult to maintain. Parts of the boardwalk has sunk making for some challenges. The Forest Service hopes to reconstruct and replace all the boardwalk in the near future.
