Bocas del Toro, Panama
Right on the border with Costa Rica sits this province of 9 main islands. Bocas town on Isla Colon is the capital, but you can easily take water taxis to any of the neighbouring islands. For a true disconnected adventure, try out Isla Solarte and the self-sustained hostel Bambuda Lodge. The area provides for a variety of water based activities, including snorkeling trips, diving, and surf spots.
