It is little known that you can do some fun free climbing in Cabo. Take a boat out to the Arch, go through the arch to the Pacific Ocean side, and climb the rocks near the water.
In our group we had friends of 12, 15, 40+ and almost 50. At times it was challenging for the older crowd, but with good tennis or hiking sandles, the climb is fun and the views great. You end up on the beach by the Finnesterra Timeshare resort! Bring water if the day is hot.
