Directions to the trailhead
One of my neighbours has some land and a house on the lake below this summit, so when he mentioned he was heading out to prepare their house for the winter, I asked if I could come to help with that, and hike up to the summit for an activation. Starting from their house at about 8:15am, I hiked across to the Deer Point campground (which has public boat access, this is another great way to start the hike, you'd park at Twenty-Five Mile Creek State Park and launch your boat from there), and then went mostly directly up, following the ridge. The Deer Point campground is essentially the trailhead when approaching the summit from the lake (western) side.
The ascent
I didn't see any trails up, other than fleeting animal paths. It was a rocky walk, and while the weather was pretty cool, there was no wind and I was sweating a lot. It's consistently 30-40 degrees of slope, but fantastic views up and down the lake. It's exposed, I was using my hands in a few spots to pull up on the rock, but it never felt dangerous. The vegetation thickened up near the top, and was damp, so I went a bit west to find a clear way through to the summit to avoid getting too wet.
The summit
I got to the summit at 11am, so it took me about 2:45 h to get up the 3300 ft of elevation from the lake. The summit itself is spacious and open, with places to operate out of the wind (it was very cool and windy while I was there) and trees to hang an antenna from. From the summit we could see the road to the north-east, and even someone walking along it. Hiking from the road is another great option to get to this submit, it would be a much shorter straight line distance, but the vegetation was much thicker, and there is the Camas Creek to cross, which is quite steep-sided (I crossed it near the lake, it was dry, but a scramble to get down and up again). So an approach from the road might not be much quicker.
The east side of the summit had a good 5G cell phone signal for posting spots, etc. HF was productive for me on the summit, using a KX3 and EFRW in an inverted V over a tree. I monitored 2m and got one S2S QSO with Lion Rock W7W/CW-030, but got no replies when I spotted and called CQ. I left the summit at about 1:15pm
The descent
For the descent I took a different route (also without a marked trail), heading down a ridge on the southeast side to take me more directly back to my neighbour's house. This was less steep and rocky than the climb up, but through tall trees and without much of a view. I got back to the house at 2:45pm, so about 1:30 h for the descent. I didn't record a GPS track or take any photos
