Will be going to Albufeira,Portugal

My son Alex is so excited of our upcoming vacation in Portugal.We will stay there for 2 weeks.He was 3 years old the last time we were there and I remember he enjoyed the color tourquoise beaches there.
We will be staying in Albufeira the whole time.Albufeira is the center city of Algarve region if I’m not mistaken.We already visited the place before but only in the center.We haven’t the chance to really explore it especially the beaches.I’m really looking forward to see those big rocks and cliffs.
