We had so much fun! It was a beautiful morning with stunning views along the route. The pedal-assist bikes are the best - and now I want one. Even with assistance we climbed some good hills and got a decent workout. There was much attention to safety - from a bike orientation at the start, helmets provided and a leader and "sweeper" to bookend our group. They would stop traffic as needed.
We made a few stops for photos, a hike to a waterfall and a walk in a vineyard.
It was interesting crossing into Switzerland and back - not a big deal, but clearly marked.
I will absolutely do this again!
Tips: wear sunscreen, bring a water bottle, and use a hands free bag/backpack/fannypack for your belongings.
