Lots of golf seems to be around there. Right now is the loggerhead turtle nesting season, that area is one of the largest...VB has a lottery for a turtle watch, you get "chosen" and they send a scout out looking for nesting activity and call you when they see it. We were fortunate enought to have one nest directly in front of where we stayed, truly an awesome experience. VB also has surf lessons - you can get out and catch some waves!

Of course walks on the beach. There's marina activities on the Intercoastal. There's a movie theatre close by...
Hope that helps!
