Welcome to the Reinhardt Redwood Tour (RRT). A number of great East Bay Regional Parks have great cache series, such as the Assault on Briones (still going strong), or the previous one in this park, "10 Redwood Caches!" (now mostly archived). This park has been a favorite of mine since childhood, and now that I've found (nearly) all the 50ish existing caches hidden here it's time to contribute a series of my own.
"Tres Sendas" means "Three Paths". I wonder which three gave this trail its name. This cache is accessible right by this path. Be sure to use stealth if others are around and LEAVE IT WELL COVERED when you replace it.
This is stop 3 of 7 traditionals hidden around the park. Take note of the 3-digit Code A written on the back of the log. Find all 7 (in any order) and collect the codes hidden on the back of the each log to determine the location of the finale: GC9WM1E
