Rattlesnake Mountain

Rattlesnake Mtn 071409220sm

The summit of Rattlesnake Mountain is the second highest point in the Rogue-Umpqua Divide and has a commanding view of the Crater Lake Rim and the southern end of the Cascades. There are two approaches to this trail. One takes off from the second trailhead in Fish Creek Valley and heads up the steep, southern side of the mountain through forest, then meadows and rocky openings before intersecting with a trail along the ridge. From here, turn left (south) to the summit. The other way reaches the summit via the ridge from the north. It is less difficult, but you miss some of the interesting plants that grow on the south slope. As a result of the high elevation, a number of species unusual for the Western Cascades can be found along and off the trail. Look for sky pilot (Polemonium pulcherrimum) in the summit rocks and cobwebby paintbrush (Castilleja arachnoidea) and marumleaf buckwheat (Eriogonum marifolium) in the nearby meadow.
