“This was an amazing trip. We took the two hour boat tour to visit the Benagil caves. We took the 9:00 AM tour and we left the marina in time to be the first boat to the farthest cave. We were in a 16 person tour, but four didn’t show up so we had plenty of room on the boat. Other tours had 20 or more on the same size boat and that looked pretty crowded.

The guide spoke excellent English…”
