First hike for me. Little bit out of shape. Found the initial 0.5 mile moderately difficult and last 0.9 miles really hard. It's full of rocks and little steeper. I had to take breaks to catch the breath and continue in that last stretch. Do yourself a favor wearing good hiking shoes.
The lake/reservoir was dry and the waterfall was not breathtaking. May be August is not the month if you want to see a beautiful waterfall and lake. But the view of the valley from the waterfall was awesome.
Start by 7am to beat the crowd and heat.
