Avalon Springs
The trip from Ravenna B&B and Avalon Springs was about 30 minutes. The 43 °C water that naturally pours from the hot springs was lovely and clear. We purchased an incredibly inexpensive day pass which gave us access to the pools and water slide that are part of the modern resort built up around the springs.
The springs are purported to have curative properties. Sadly, my knees aren't miraculously better. They still hurt as we were driving home.
