Despite the sea being a bit rough, this was a nice beach even for our 5 yr old to enjoy. Sand is a bit darker than at some other beaches (so hot to the feet after some time in the sun) but very fine and clean. The beach is very wide, has lots of trees bordering it for shade. So plenty of room for you to choose sun or shade spots. It's a bit hard to find located in Kioskos area. If you're going east on PR-3, just before reaching Luquillo proper, you see a ramp on the right before a bridge. Go under the bridge and straight to reach the entrance booth where they'll only charge $4.38 entrance fee per car. If you want to use their showers and changing rooms, there's a $1/pp fee but that was worth it at the end of the day. There are facilities, reasonable cheap vendors and souvenir shops. No pushy beach vendors either. They also rent kayaks $5 per half hour so plenty to do for everyone. We were there early afternoon midweek and it was not crowded at all. The kids loved the ice cream vendor right on the beach. Just watch out for the black birds. They can get pretty territorial. Overall a great day on a wonderful family beach.
