A trip to through the lush rainforests surrounding Arenal Hanging Bridges may be perfect for nature lovers, but it’s not for the faint of heart. That’s because 16 bridges—some suspended high above gorges and others stretching far across jungle floors—line the winding paths of this epic Costa Rican hike. Visitors can wander through thick vegetation on well-marked trails, look for families of monkeys swinging through the air, and spot lazy sloth lounging among tree limbs. Despite their height, bridges are stable and secure. And while heavy rains can make parts of the path difficult to navigate, a hike through this forest in sunny weather is a perfect way to spend several afternoon or mid-morning hours out of doors.
