If in the south of Portugal, a boat trip around the coastline off Lagos is a must. This natural coastline beauty is a must see and for a small cost of approx 10 euros per person (we paid $8 in the offseason) you can get a small boat ride which will take you through some of the caves and further down around the amazing coastline. I think we were on the water for approx and hour and we all felt it was great value! Lagos is a laid back, friendly place with great little shopping streets and some good restaurants. We recommend Lemongrass Thai Restuarant !
