One of the few working water spigots on Diablo. Always tastes cold and fresh.

One of the fiercest peaks in the Bay. Always worth the effort. Itβs often much cooler on the summit than the rest of the trails β there is a water spigot up there to fill up bottles. Also a store is open at some times. Donβt bank on it.
