End of March 2023: campground is currently closed while they clean up several down trees and a whole lot of branches that came down in the storms this winter. The bathroom was open though, it was clean but had no TP. No problem since I was actually there to hike all day. The gate was closed to the campground and we parked outside.
We took the trail behind the campground all the way up to Sierra Madre road where there was snow and cold wind. The first part of the trail had many stream crossings, some of which were too wide to keep feet dry, though not deep. There were also several areas of blow down. For maybe 50 yd there would be numerous small or large trees across the trail. Some areas were very dense, and required crawling under or climbing over branches. I assume they had wind bursts during the storms.
After that when we got to the open spot that has a fire circle in it (about 2 miles) we had lunch. Then we headed up the trail to the left to Sierra Madre road and that trail was in excellent condition. Quite beautiful views. I would love to come back in the spring or fall and camp at Aliso Park Campground.
