Puerto San Andrés is located just up the road from Punta Rosalillita. It's a spot that can attract both surfers and windsurfers due to its strong offshores. While the access road might not be the best, the beach does provide some opportunities for those looking to catch some waves.

The surf here works best with a swell coming from the west or northwest, and it handles swell sizes starting at 2ft (about 0.6 meters) and can go larger. Waves tend to break over uneven reef and sand, producing point breaks, mostly going to the right. It's a good idea to hit the water when the tide is low, mid, or high for the best ride. Beginners might find this spot a bit challenging, so it's more suited for intermediate surfers looking for that hollow wave experience.

This beach is known for its beachbreak at Tres Alejandros, which adds to the variety of conditions you can experience. On a good day, you can find some real fun waves here, especially with the right wind from the northeast.
