Climbing up Mount Tamalpais, you'll find many great spots for admiring the scenery, but this one particularly struck me because, almost immersed in nature, you can see the city skyline in the distance. I found it so moving that I stopped my bike and stood there contemplating the landscape for a few minutes. The climb is a bit steep, but it's definitely worth it!

At the end of the gradual Tennessee Valley Road, the last mile or so unpaved but smooth gravel, awaits the natural sandy wide beach cove. The steep coastal trails climbing on either side are hiking only.
