This was our second short hike yesterday. After our first one at Grassi Lakes we decided to drive up to Spray Lakes to look around. Roads are dusty we need rain. We went up and parked on the dam at the second lake, which is not really a lake any more. Bit of a river. No water. No snow. Sitting there I looked west and saw a short trail up the hill on the opposite side of the road. A little further up looked like there may be some run off and maybe a waterfall of sorts. So, we drove over parked in the little lot and climbed up. Once we got a little further up you could see a wash where the flooding happened - we kept climbing on the rocks up to several tiers of waterfall. Some was a little tricky - no paths.
Short hike 10 minutes in, then whatever if you want to climb up the rocks through the falls.
