I absolutely loathed this one. Its the only "hike" I've ever actually disliked and was my first in southern California. The walk from the parking lot to the reserve is a very nice and shaded stroll...but it opens to very exposed reserve (which is to be expected of so. Cal's landscape). Its very dusty and gets steep very quickly at times. Its a rather short hike and the end is very steep pavement that ends at the fenced off reservoir. The views aren't worth the strain, you're better off going to the park a little ways down the road where there are multiple trails between Mt. Woodson and Lake Romona...also, there are no hot springs.
Whoever wrote this trail features hot springs is mistaken. There are no hot springs in this area. However, it is one of the few trails in San Diego county that feature lots and lots of trees. Interesting in that the majority of Blue Sky is owned by the state, with the city of Poway owning the parking lot and the first part of the trail and the county of San Diego owning the back part of the the trail. Best option is to take the branch of the trail leading to Lake Poway. Just below the dam is one of the best tree covered and isolated picnic areas in the county, complete with rest rooms. Early in the morning there are mule deer around an adjacent stream near the west base of the dam. On hot summer days I have seen rattlesnakes in this area, so use caution and keep those dogs on a leash. No bicycles allowed in Blue Sky.
Great and easy hike!
