On the same day, is it possible to get from Jarabacoa to Las Terrenas with a stop at the Museo Hermanas Mirabal in Salcedo/Tenares using buses & guaguas? How?
Take the bus from Jarabacoa to La Vega and in La Vega take a guagua to Salcedo... Then from Salcedo to San Francisco and in San Francisco switch to the Samana-bound bus.
