I’ve hiked several of the Idyllwild trails in August. Other than it being a little warm at the lower elevations, it’s been beautiful above 7000′. The small gnats that have invaded the lower elevations are gone above 7000′. I did notice several downed trees on most of the trails. And some of the trails (PCT) need some trimming, due to plant (poison oak) overgrowth.
I didn’t find any water except for the stream crossing the trail just below Little Round Valley. So make sure you bring plenty of water on your hike. I don’t consume a lot of water normally but with the warmer weather I’ve been consuming about 60oz on a 6 mile hike and even more on longer hikes. Wildlife seems to be venturing down lower in search of water also. I’ve seen several deer along the way.
I find myself lucky to experience these local trails on a regular basis, and hope you also come up and experience this natural wonder in Southern California.
