Pine Grove is the east-end Isla Verde sandbar that gives San Juan a practical beginner surf option. The wave is usually soft, accessible, and close to hotels, surf schools, rentals, and the airport. It is best for foam boards and longboards on small clean days; stronger wind or north swell can add backwash, rips, and enough punch that brand-new surfers should stay with an instructor.
Use the public beach access points around the east end of Isla Verde. Stay clear of swimmers and check local flags before paddling out.
