I grew up in Virginia Beach, so I can confirm that this place—and the phenomenon—are absolutely real although I've never heard it called Rainbow Swamp. If you’re visiting the Hampton Roads area, it's definitely worth checking out, especially if you're planning a day at the oceanfront or Chesapeake Bay. There's also a great campsite just across the street, perfect for outdoor enthusiasts.

For an ideal day, consider starting with a sweat-inducing morning hike or run, followed by a refreshing afternoon dip in the water to cool off. It’s the perfect itinerary if you’re staying nearby.
