Head to Tesoro Escondido Waterfall this morning. Meaning ‘hidden treasure’, this 46-m-high waterfall plunges into turquoise pools and is the perfect place for a dip. The trail to get there involves hiking through the forest, over a hanging bridge and across a rock-strewn river. Don’t worry if you work up a sweat, as you’ll cool right down when you jump in! Have lunch at a nearby restaurant, then continue to La Fortuna – a small town just a few minutes from the famous Arenal Volcano. Spend the rest of the day as you please. Maybe make another splash at the 70-m-high La Fortuna waterfall, hike the lava field of the 1968 Arenal Volcano eruption or test your balance on a stand-up paddle board on the volcano’s namesake lake. There are also several geothermal hot springs in the area, so why not relax your muscles with a soothing soak?
