In a tech-heavy world, there are still peaceful, relaxing corners to enjoy. I had the chance to visit one up close last month when I traveled to Onera in Wimberley, Texas. About an hour's drive south from Austin, Onera Wimberley sits on 20 quiet acres and is considered a luxury landscape hotel. The 12 treehouse-style units and 16 greenhouse units take sustainable "glamping" a step further with modern accommodations and a nice list of amenities.
