We recently did the one day hike, Cascada del Arcoiris, offered by Frank of Costa y Cumbre Tours. It was a wonderful day following a cowboy trail through the vast landscape of the Andes, the trail is a hidden gem with not a soul in sight and multiple huge waterfalls, one of which we swam in. Wildly remote and with dominating scenery this is an incredible journey – we recommend Frank’s tours highly. He specialises in journeys that are off the beaten trail and have a little something extra special, check out his website for more info and details of the many different hikes he offers. Hopefully we will head to the sand dunes in Constitución next.
