The bus stops in the town of Ver?n on the way to the airport. The buses that don't go on to the airport continue to B?varo.
Note that "B?varo" is not a specific point but the name used for part of the area (Punta Cana - B?varo) that covers about 40 kms of coastline from Cap Cana to Uvero Alto.
If you want to go to the beach it would depend where you're staying, otherwise the beaches with public access include Cortecito, Los Corales and Bibijagua (these are in what's known as B?varo), and Macao and Uvero Alto to the north. Nearer the airport - Cabeza de Toro and Cabo Enga?o, and Playa Blanca in Punta Cana.
