The Length of the Island
This was our first cycle-tour in more than 20 years, our first overseas tour, and we’d recently bought our first new bikes in decades. We pedalled westward from Havana through Pinar del Rio province, then took a bus to Baracoa in the southeast. From Baracoa, we crossed the Sierra Maestra over the pass called La Farola to the dry and windy south coast. We worked our way back to Havana across the plains and through central Cuba.
