The hot springs or aguas termales located on the North side of the lake are frequented by many visitors, however, with the current raise in bacteria along the shore it is not advisable to get in the water at this time.
Santa Catarina is a great place to walk. A trip up to the onion fields above the village is highly recommended. To get to the onion fields just head up one of the footpaths towards the residential area. Go up and keep going up. If you ask people along the way, they will be more than happy to direct you to the onion fields. When you get to the top you will see an array of onion fields, corn plantations, and fields of flowers. It's a truly beautiful place and the views of the lake are amazing!
