Last Sunday, Anna and Minna took a group of students kayaking at the Charles River and enjoyed the beautiful weather and view of Boston. There are five different locations in Cambridge, Boston, Newton, and Natick. I would recommend starting at the Cambridge location in Kendall Square so you can view the Esplanade and the Boston skyline.
It costs $15 per hour to rent a single kayak and $18 for a double kayak. You can also book a one way trip from Cambridge so you can drop off your kayak at another location. Charles River Canoe & Kayak is open at different times during the fall so make sure to check out their schedule on their website beforehand! Make sure to go before the weather gets cold!
