Aqua Dome

Located 45 minutes outside of Innsbruck, the 500,000-square-foot Aqua Dome boasts a spa, hotel, restaurant, several pools and fitness center with different types of classes. In the winter, it is a great day trip for skiers in neighboring mountain resorts to take a day off and unwind. Be aware, though, that those who don’t do well with nudity in public spaces should most likely avoid.
