Assateague Island State Park FAQs

Common questions for visitors planning wildlife time near Ocean City, Maryland.

Will I see wild horses at Assateague State Park?
Often yes, but not guaranteed. Horses roam; dawn and dusk help. Stay at least a bus-length away, never feed them, and secure food at campsites.
What is a sika deer and where do I look?
Sika are small Asian deer established on Assateague. Look along marsh edges and forest/scrub at dawn or dusk. Drive slowly on park roads after dark.
Can I fly a drone for wildlife photos?
Drone rules are restrictive on Assateague and can disturb nesting birds and horses. Check current Maryland Park Service and National Park Service rules before flying—assume no unless posted otherwise.
Is Assateague State Park enough for a half-day from Ocean City?
Yes. Many visitors combine a beach walk, dune overlook, and marsh viewing in 3–4 hours, then return to Ocean City for dinner.
