You will need a vehicle or transportation to the beach as it is not in "town" but not necessarily a jeep. There are paved roads right up to the beach.
There are taxis, but there is poor cell phone coverage so to get back to the hotel will be difficult. There are several Jeep rentals which makes your transportation safe and convenient.
Hope you enjoy Vieques, Caracas beach is stunning.
