Hiking a well-graded and a bit rollicking trail along the river in a steep-sided basin. Lots of evidence of post-fire ecology: wildflowers were riotous when we went (but so was poison oak). I didn't make it past the lower falls and was totally fine with that. Marked a few campsites I'll try next time. My trip report: https://bl3ssthism3ss.wordpress.com/2020/06/12/preston-falls/
