Know Before You Go
Tour companies will offer you a shuttle to and from the Casa de Arbol for as low as $5 each. They leave multiple times a day and are great if you prefer the ease of shuttles and you don’t mind long lines, limited time, and huge groups of people. You can also take a bus that leaves from the center of town and goes straight to the Casa de Arbol. It costs $2.50 and you'll be waiting in far fewer lines at the swing.
When you pull up to the Casa de Arbol, you will immediately see a tree house with a swing at the top of a steep hill. This is not the Casa de Arbol; it is actually up a little trail and on the other side of the hill. But, this is a giant swing over a huge hill, and it’s cheaper than the Casa de Arbol (by $1) and has less lines. So by all means give it a try if you like.
The actual Casa de Arbol is to the right and up a short trail. Or, hike up the path to the Bellavista Cloud Forest Viewpoint from Baños (3-hour hike, less than 1 km). Casa de Arbol costs $2 to enter, which includes all three swings and the zip line. There is a small cafe on site as well with food and drinks for purchase.
