Redwood grove at Carbon canyon regional park (Orange county)

The Redwoods grove at Carbon canyon park is the only place in Southern California where redwoods have been successfully grown into a full grove.
Normally from Northern California, they need cooler and wetter climates.
A local bank back in the 70s gave away Redwoods seedlings to its customers, and upon closing, ended up giving away what was left to the local park where they were planted.
It is a very easy walk, accessible to all, even kids, and is a nice change of landscape.
