Spending a night in La Boca was one of my favourite bits of our 10-day Cuba Itinerary.
You can escape the known travel route and stay a night at the lake with the most amazing food. From La Boca, you can easily bike to Playa Ancon to spend a day on the beach. We were able to rent our bikes at the accommodation we stayed, as biking around is quite a usual thing to do here!
