Twin Pillars Trail (#832)

Twin Pillars

This is a beautiful trail that travels through Mill Creek Wilderness and actually crosses the East Fork of Mill Creek countless times. Because it is in a wilderness area there are no bridges to facilitate the stream crossings, so make sure you are prepared for the adventure when you come. Water levels tend to be highest in the spring and lowest in the fall.  

In the 1990s there was a wildfire in the wilderness and the damage can still be seen all along the trail; however, the grasses and shrubs are now recovering nicely. Since the fire the area has really opened up, and the terrain and scenery has become much more visible, meaning that views of the Twin Pillars are far better than they have been in years past.

This trail can be accessed from Twin Pillars North Trailhead and Twin Pillars South Trailhead

As a side note: This national forest has a long history of cattle and sheep grazing, and because of this if you decided to explore this wilderness area in the summer months you may encounter some.  If you do please use caution and do not approach the animals.

This trail receives fairly heavy use, especially during the summer months.  Cattle are  allowed to graze in this area.  The highlight of this trail is the contrast between the thick stream vegetation and the ponderosa pine forest, as well as views of the Twin Pillars, which are 200 foot tall volcanic plugs that dominate the landscape.
