  • Fall color is lovely in the area, and camps are available at all the lakes.
  • Scramble Alta Mountain from Lila Lake if your party's up for that.
  • Instead of retracing your steps back to the Margaret Lake-Lake Lillian trailhead consider exiting steeply down past Rachel Lake to make a loop to the Rachel Lake trailhead. Remember to set up a car shuttle.
  • An alternate hike to Lake Lillian follows a "fisherman's trail"  that passes Lake Laura. It's very steep, easy-to-follow trail, a bit of a scramble in places, but is a much shorter hike to Lake Lillian. It's part of our Rampart Ridge route/place.
