Iron Mountain

Forest: Willamette National Forest

District: Sweet Home Ranger District

Description: Set aside for its botanical interest, Iron Mountain provides habitat for more than 300 species of flowering plants, which share their beauty throughout the summer season. The Iron Mountain Trail passes through several meadows interspersed with alpine trees before reaching the bare volcanic rock at the top. This Old Cascades area is a wonderful hiking experience with meadows, springs, alpine environments, and a tremendous variety of flora. An interpretive brochure is available at the trailhead.

You can take a loop hike around Iron Mountain by connecting the Iron Mountain trail with the Cone Peak Trail and Santiam Wagon Road.

Viewing Information: Iron Mountain is a well-known Special Interest Area distinguished for its botanical qualities. Eighteen different plant communities and over 300 species of flowering plants are found along the trail. The most famous are the 5 species of penstemon, notably the red rock penstemon. To catch those blooms at their height, plan to go during early July. However, if one comes in June, one may see a unique snow bed flora- plants that emerge just as the snows melt. Examples are steer’s head, glacier lilies and turkey pea.
