Consider a family vacation or adult- only adventure learning to surf (or improving your skills ) A friend of mine did a few days in Costa Rica's adult camp for his bachelor party.
Surf schools are located all over, from California to Australia, and even in Montauk, New York. Some top-ranked schools we found are in Kauai, Hawaii, and Costa Rica. If you choose a week-long school, many have accommodations by the beach and include food and drink. You don't have to surf all day, every day. You can kick back and enjoy the beach and take optional excursions.
Witch Rock surf camp - Costa Rica
Del Mar surf camp - California
Kauai surf school - Hawaii
Make sure you check school reviews before choosing and confirm the school is not only for youths.
If you would prefer to learn to surf indoors, there's a park called Sky Venture in New Hampshire that you might want to try. It looks like a great time.
