We visited the Sunny Jim Cave in La Jolla, California in the San Diego area. It was a treat to see and experience (for a surprising low $4 charge). As you could read from the sign the tunnel is over 110 years old. I did not see the sign going down but my son pointed it out coming back out as I was huffing and puffing the last few steps up. You can read about the history here. It took 2 years for them to build this magnificent cave.
This was a unplanned visit after the 4 hour walk through the San Diego Zoo. The beaches in this area were spectacular as you will see in the coming posts. I really feel in love with the La Jolla area of San Diego.
Have you visited a cave like this near the ocean?
