This is a fun loop with a side trail up to the Timberline Trail via Mt Hood Meadows. The loop can be done either clockwise or counterclockwise, but the preference is to hike it counterclockwise. Start at the Elk Meadows trailhead and if you time it right in August, you will enjoy ripe hickleberries as you make your way up to the left turnoff at trail #667 which leads to Umbrella Falls. After visiting the falls, you can take the 1.7 mile optional trail up to the Timberline Trail by crossing over the paved road that leads to the Mt Hood Meadows upper ski area. Find the trail that leads to the Timberline Trail just north of the new maintenance building hidden in the woods. When you return back to Umbrella Falls, look for the sign that is marked #667C that will lead you down to Sahalie Falls and back to your vehicle.
