When Patricia Thorndike de Suriel, owner of Iguana Mama Mountain Bike and Hiking Vacations, first visited the Dominican Republic’s north shore in 1993, the upstate New York native immediately saw the potential for biking in the surrounding terrain. She scouted hundreds of trails, from paved roads and goat paths for beginners to technical singletracks down the mountainside for the truly gifted. The result is a wide array of full-day and half-day jaunts for all levels of expertise. The Islabon Coast Cruise combines an easy ride along the coast with a boat trip down the Yasica River — perfect for the whole family.
