We had a really good experience doing the architectural tour with Kayak Chicago! It was easy to book our trip on the website. The drop-in spot is just south of North Ave and has easy parking. The staff members were all welcoming and helpful, and we really liked our tour guide. There was a good mix of learning about the history of the river and buildings along the river, plus some time to just relax and kayak down the river. We brought our 7 and 8 year old children with us, and they enjoyed it too (children sat in front of a double kayak with an adult in the back). This is a really great way to spend some time in the city and see what Chicago is all about.
