The mountain biking tour in La Fortuna is a perfect adventure for nature lovers, highlighting the ‘Lago Arenal’ route. Ranging between 13 and 26 km, it starts just outside the Arenal Volcano National Park, where guides provide safety instructions and proper equipment. The tour follows the southern shore of Lake Arenal, Costa Rica's largest man-made lake, to the village of El Castillo, where you will learn the story of how it was affected by the volcano's eruption in 1968. Then, the ride continues to the Caño Negro River, important for its contribution to the lake. After crossing the river, cyclists will ride along an abandoned road that connects to Monteverde, passing through streams, rocky areas and protected forests. During the route, there will be a break to enjoy a picnic with fruits, energy bars, seeds and drinks. Finally, the route returns to Arenal Volcano National Park, giving participants a complete experience that combines cycling, adventure and spectacular scenery in one of Costa Rica's most iconic places.
