Our hotel host recommended this beach (as opposed to the beach in Alicante, which is full of…read moretourists). I'm so glad we went to San Juan Beach!!! The place is full of locals - they know what's up.
Parking was quite tough - there is a lot of street parking nearby, but you have to be lucky. Getting there early will help in all aspects. It was an extremely crowded beach, but the beach is HUGE - so you are quite spread out and have your own area, which is nice. They also have a "San Juan Beach Club" - which is basically rental lounging chairs & beach umbrella, for only 14 euros for the day!!! It helps to go early though, as the rentals will be occupied quite quickly.
The sand was awesome - very powdery, although quite hot! The water was a bit cold, but with the 90 degree weather, it was nice to tread in the water ankle-deep.
To put in comparison with other beaches, this beach reminded us of Santa Monica in California. The people, the laziness, the beauty of the city, the nice weather, the slight classiness of the beach & area, the buildings surrounding, the difficult parking, etc. It was fun to drive around the area too, as their boulevards you drive on next to the beach are spectacular.
Highly recommended if you want to visit a beach town in Spain!!!
