One of the best things on the Northern Neck! Shark Tooth Island is visible from Easthaven, on the Potomac. Accessible only by boat, it’s an amazing place with a huge beach to go exploring for shark tooth fossils, of which there are plenty, sunbathing, fishing, picnic, meet up with people, build sandcastles, party, or relax. Maybe even see dolphins! Great activity during a spring break trip or summer break vacation. Cannot recommend it highly enough.
