What is Assateague Island?
Assateague Island is the undeveloped barrier island directly south of the Ocean City Inlet, protected as Assateague Island National Seashore and, on its Maryland end, Assateague State Park. It is known for free-roaming wild horses, wide natural beach, marsh trails, camping, paddling. Despite being visible from Ocean City, it is reached only by driving inland through West Ocean City and south on Route 611, roughly twenty to thirty minutes. Entrance fees, park rules, and wildlife distance requirements apply.
Also called: Assateague, Assateague Island National Seashore.
Two agencies, one island
Two agencies share the Maryland end. A National Park Service unit and a Maryland state park sit side by side, with separate entrances, fees, camping systems, and rules. Confirm which one your plan involves before arriving, because a state park day pass and a national seashore pass are not interchangeable and the campgrounds book on different systems.
The horses are wildlife, not attractions
The free-roaming horses are wild animals that kick, bite, and damage cars. The park requires visitors to keep a substantial distance, secure all food, and never feed them. Sightings are likely but never guaranteed, and planning a trip around a photograph tends to produce both disappointment and bad behavior. Treat any encounter as something to back away from.
What to bring that Ocean City does not require
There are no shops and almost no shade. Water, food, sun protection, and insect repellent are the difference between a good day and a short one, particularly in mid-summer when greenhead flies work the beach. Check park conditions, closures, or mosquito reports the morning you go.
