From the Organizer
Vacation Isle sits at the center of Mission Bay — a bona fide island, connected to the mainland by a single road and surrounded by sparkling blue water in every direction. Open lawns, shaded trees, sandy beaches, and bay breezes make this one of San Diego's most scenic venues. And yes, July mornings here are just about perfect.
Whether you're picking up a map for the first time or you've been navigating by compass for years, you'll find a course built for you. Beginners get a welcoming, manageable challenge in a gorgeous setting. Experienced orienteers get terrain that rewards sharp navigation. Everyone gets to spend a Saturday morning on an island. 🧭
