Dahlgren Wayside Park looks moderate today, with about a 46% chance of encountering stinging jellyfish.
Dahlgren Wayside Park is a small Potomac River park at 3435 Roseland Road in King George County, right by the U.S. 301 bridge. The county lists a sandy beach, fishing, grills, kayak rentals, parking, and picnic areas. It's an easy waterfront stop for a picnic, some fishing, bird watching, or putting a rented kayak in the river, and it's part of the Virginia Bird and Wildlife Trail.
It's a compact park, so bring what you need for a short beach-and-picnic visit, and don't count on amenities beyond what the county lists. The park is closed from dusk to dawn, and the county has talked about future improvements, so a few things may change over time.
The water here is the wide lower Potomac. Check the reading above for the day's jellyfish outlook before you get in.
Before you swim, look at the flags. Lifeguards fly a purple flag when dangerous marine life, including jellyfish, has actually been spotted, and that beats any forecast. If the flag and this page disagree, trust the flag.
About Potomac River jellyfish
The lower Potomac around the Northern Neck sees summer sea nettles where the water is saltier near the bay. Upriver toward Alexandria and Washington the water is usually too fresh for many nettles. Colonial Beach and other lower-river spots are the ones to watch in mid to late summer.

Beach Bag Sting Kit
A few simple items make a jellyfish sting easier to handle and less likely in the first place. We haven't lab-tested these ourselves — these are the picks that came out on top when we compared reviews, reputations, and Amazon track records. Here is what we suggest keeping in the beach bag during sea nettle season.

Sting relief gel
After Bite Xtra is the pharmacist-recommended favorite in sting-treatment roundups, with a gentle diphenhydramine formula for the burn and itch once you are out of the water.

Small vinegar bottle
There's no jellyfish-specific vinegar bottle out there, so we like a small leak-proof silicone travel bottle (humangear GoToob+) you fill yourself — handy for beaches where local guidance calls for vinegar, though it's not a clear win for bay sea nettles.

Rash guard
O'Neill's Basic Skins UPF 50+ long-sleeve is the name that keeps coming up as the reliable no-frills pick for covering skin that sea nettles would otherwise reach — just size up, reviewers say it runs a little small.

Water shoes
The Speedo Tidal Cruiser is the well-reviewed, widely available pick for keeping feet protected from stings and shells in shallow water. (Speedo discontinued the older Surfwalker Pro 3.0, so this is its current equivalent.)

Beach umbrella
The Sport-Brella Super-Brella is the recurring 'best overall' pick in shade-umbrella roundups, with vents, stakes, and tethers included to help it hold up in a stiff bay breeze.
