We rented bikes for about 5 euros for the day. It was a good workout to go all around the island, which is not entirely flat, and basically coast right next to the ocean.
Some pics of Xiao and Dan with their bikes. Behind Dan is the castle on the island.
After about 2 hours or so of biking (unfortunately, Dan got a flat and had to exchange his bike) we decided to cool off in the sea! It was so refreshing just to jump in and the waters are surprisingly shallow. We got some gelato, jumped on the ferry back, then headed back to Palermo via train. It was a great first weekend exploring Sicily!
