Big Island Watersports - Jet Skiing in the Ocean!

Surfing/Surf lessons - Our surfing areas are all reef-breaks and a bit dangerous. You can't surf on the sand beaches in the Kona area. I'd highly recommend surf lessons from Hawaii Life Guard Surf Instructors. Even if you know how to surf, you need at least some guidance form a local pro on our reefs(covered in sea urchins), currents, etc.

Check them out and tell Tifani Joe with Big Island Jeep Rental sent yah-
