Twin Lakes Mountain is a 4-point summit located in the Umpqua National Forest. It can be reached from Hwy. 138, approximately 58 miles east of Roseburg, OR. From there, 9 miles of forest road yields a 2.6 mile hike (each way) on well maintained trail, with views of Diamond Peak, Twin Lakes and other local features. This would be a good stop on the way to Diamond Lake and environs. This summit is close to Illahee Rock, which is on the north side of 138. Combining the two wouldn't be too much trouble.

From Hwy. 138 (43.29122, -122.56450) turn south onto Wilson Creek Road (aka NF 4770). Remain on this mainline for 9.2 miles to the parking area and trailhead for the Twin Lakes trail (1500). In approximately 0.8 miles, turn left at the junction, and proceed 1.5 miles uphill until you find a good place to turn off trail and head to the summit. This is about 0.2 miles of bushwack through mixed foliage and some treefall. Use your judgement here on route.

The summit area has both open areas for verticals and trees for wire antennas. Don't plan on much 2m action here. Cell service is marginal but worked enough for a few spots.
