GULF ISLANDS NATIONAL SEASHORE, Fla. -

It's been four years since the massive 2010 BP oil spill hit the Gulf of Mexico. The superintendent of Gulf Islands National Seashore is kayaking the Florida Panhandle's protected beaches and highlighting the region's recovery.

Dan Brown began his 58-mile kayak trip on April 19. He has been joined by residents and community leaders on daily legs of the trip. He plans to end the trip this weekend in Destin.

The trip also highlights National Park Week.

Brown said the full extent of environmental damage from the oil spill might never been known, but that the region's white sand beaches are mostly free of residual tar balls and wildlife appears to be doing well.
