Cocoa Beach is 64 miles away from Walt Disney Word Resort. It should take about an hour's drive on the nose without bad traffic. Daytona Beach distance is 78 miles or about an hour and a half and Clearwater beach distance is 89 miles and also about an hour and a half drive. Disney's Vero Beach Resort is 97 miles and about an hour's drive plus 45 minutes.
Actually the Atlantic Ocean also includes the Gulf Coast beaches as the Gulf Stream is fueled by the Atlantic Ocean. However the closest beaches near Walt Disney World are on the Space Coast. The Space Coast is named that because of the Kennedy Space Center and Cape Canaveral National Seashore. We just call them east coast beaches and yes they are closer than the closest Gulf Coast beach.
Not only is Cocoa Beach a beautiful beach and the closest beach to Disney World but it is a comfortable day trip just over an hour away. If you nd supplies for that relaxing beach vacation the Ron Jon Surf Shop has you covered at the north end of Cocoa Beach. White sand beaches await you and so does the Cocoa Beach pier. If you are curious this is a barrier island and the intercoastal is named Indian River Lagoon. The Cocoa beach distance, well worth the drive.
Some options and the closest beaches to Cocoa Beach are Vero Beach to the south and the Vero Beach Museum. Disney's Vero Beach Resort is often forgot about. However it can still be part of a Disney World Vacation and the white sandy beaches sure beat any of the normal amenities Disney Hotels normally offer.
Keeping with the theme, Daytona Lagoon Waterpark is very much still a thing. Not many Florida beaches have a pier and far fewer have their own waterpark. Lest we forget the Daytona International Speedway. There is so much here that the white sand beach can get overshadowed. However, for a day trip and a unique one Daytona Beach is very much a thing to do and just over an hour away.
Another Atlantic Coast beach just south would be New Smyrna Beach. A little further south is Apollo Beach which is also a name used by one of the gulf beaches. If seclusion is what you are after these last two are great options and have white sandy beaches.
To the north of Daytona Beach is Ormond Beach and many other before reaching St Augustine Beach. Actually it is fun just to drive along the coast on a motorcycle or in a convertible. All that is lacking north of Daytona Beach is a Disney Resort, nah.
A Disney vacation is an expensive thing. We all know that is true. If you want to go in a little deeper but discover another craving then head to the Gulf Coast beaches. Actually they are the best beaches near Disney World. Clearwater Beach is the top destination. St Pete Beach distance is an additional 20 minutes and not really necessary. Both are very similar and can round off any Walt Disney World vacation.
Other West Coast beaches? The Anna Maria Island distance is worth the trip, Siesta key Beach is also highly thought of, Sand Key County Park is also very nice and among the popular beaches and destinations on Florida's Gulf Coast. Pack you stuff, The beaches are very close to Walt Disney World.
