Today, you’ll make your way to Rio Dulce by private vehicle, arriving mid-afternoon. Along the way, your leader will give you an informal Spanish lesson. Rio Dulce, which means 'Sweet River' in Spanish, refers to both the Guatemalan river that flows from Lago de Izabal (Lake Izabal) to the Caribbean Sea and the town of Fronteras, which sits at the east end of the lake. When you arrive, the rest of the day is free to rest or explore at your own pace. Maybe stretch your legs on a jungle walk, rent a kayak and get out on the water or take it easy in a hammock.
