Master the Waves: Surfing and Kayaking Adventures
San Diego’s identity is tied to the Pacific Ocean. Instead of just sitting on the sand, get in the water and learn a new skill. The ocean offers some of the most rewarding and challenging experiences in the county.
Learning to Surf in La Jolla or Pacific Beach
There’s no better place to learn to surf than the city that lives and breathes it. The gentle, rolling waves at spots like La Jolla Shores or the north end of Pacific Beach are perfect for beginners.

This initial investment pays off massively in confidence and safety. Look for surf schools with a low student-to-instructor ratio for more personalized attention.
Kayaking the La Jolla Sea Caves
For a different perspective of the coastline, rent a kayak and paddle out to the La Jolla Sea Caves. This protected ecological reserve is teeming with wildlife, including sea lions, dolphins, and bright orange Garibaldi fish.
You can book a guided tour (highly recommended for your first time) or, if you have some paddling experience, rent a double kayak with a friend. The guides know the tides and can safely lead you inside the Clam’s Cave, which is an unforgettable experience. This is one of the best eco-friendly things to do in san diego for 19 year olds.
Essential Gear and a Basic Care Guide for a Day on the Water

- Rash Guard: Wear this under your wetsuit to prevent chafing.
- Reef-Safe Sunscreen: Protect your skin and the delicate marine ecosystem. Apply it at least 20 minutes before getting in the water.
- Dry Bag: A small Sea to Summit dry bag is perfect for keeping your phone and keys safe and dry on the kayak.
