Tam McArthur Rim is one of the most popular hikes in Central Oregon and for good reason. It is moderate in difficulty and offers absolutely spectacular views of the Cascade mountains as well as some of the amazing blue-green alpine lakes nearby. You can choose to keep this hike short and family friendly at 5.6 miles round trip, or you can continue on the trail around Broken Hand and go all the way to Broken Top No Name Lake, making it a much more difficult hike at 11.5 miles roundtrip and 2,000 feet elevation gain.  The parking area is large but even so, the trailhead fills up and cars spill out onto the main gravel road during summer weekends even with the limited entry permit system that was put in place in 2020. It is recommended to do this hike on a week day and/or very early in the morning!
