This treehouse and swing combination isn’t for the faint-hearted. La Casa del Árbol (The Treehouse) in Baños, Ecuador,is a seismic checking station built on top of a single tree on the edge of a cliff face. While the treehouse itself is a unique structure, it’s the swing that really steals the show. Called the “Crazy Swing” and fastened to the treehouse above, you can take a swing out over the cliff edge which is 8,350 feet above sea level.” – Niall
