Rummel Lake is a great, easy hike across the Smith Dorrien from Mount Engadine Lodge. The trailhead is right off the road and immediately takes hikers on a peaceful and easy trail that gradually gains elevation until you reach the lake.
Along the route, multiple forest openings offer fantastic views of the Spray Valley. Commonwealth Peak, Tent Ridge, The Fist, and Spray Lakes are notable peaks. There's even a nice bench perfectly placed to take in the views.
After the viewpoint, you'll continue climbing until reaching Rummel Lake. Here, take a seat and enjoy the lake under Mount Galatea. It's a tranquil setting and the perfect spot for a picnic lunch in nature. The cirque, headwall, and Rummel Lake are all of particular beauty. If you're visiting in September, plenty of surrounding larch trees will turn golden toward the end of the month!
