As part of our 3 day trip to Arenal, six of us (two couples and two 4 month old babies) travelled to see the Arenal volcano. The volcano has not been active since 2010, but it is still a sight to see and there are lots of other local attractions. One such attraction is the Arenal Hanging Bridges walking tour. Located up one of the longest modern roads paved with individual bricks I’ve ever seen, which starts just under the Arenal dam. The dam caused the Arenal Lake to triple in size when it was built and provides water to a hydro-electric station which provides somewhere between 40 to 70% of the countries electricity.
