Barrier Peak, along with Governors Ridge and Tamanos Mountain, is one of the high peaks which rings the valley containing Owyhigh Lakes. It lies within Mount Rainier National Park and is connected via a long ridge with Governors Ridge. As such, an ascent of Barrier Peak is often combined with one of Governors Ridge as well. Barrier Peak provides great views of the nearby peaks such as Tamanos, Governors Ridge, the Cowlitz Chimneys, Banshee Peak, and, of course, Mount Rainier. The Goat Rocks Wilderness, Mount Adams, and Mount Saint Helens are easily viewable from the summit as well.
Barrier is a moderate scramble which, depending on the route, can give any level of challenge. While there is no good "climbing" rock, the scramble can involve challenging scrambling terrain and loose rock coming from the saddle near Governors Ridge, meadowy strolls coming from the west, or steep snow coming from the basins below the peak. Barrier is a fun peak which is easily accessible and is perfect for a short day in the mountains.
