Join the City of Cambridge Water Department Staff on our 10^th annual Cycle to the Source Watershed Tour.

This event is free and open to the public, but for safety reasons is for adults only. **Please note, due to the awesome amount of interest we received last year, priority for spots will be given to Cambridge residents and first-time participants.**

What: Cycle to the Source is a 32-mile bike tour of the Cambridge Watershed. It is a chance to explore where your water comes from, how it is collected, and what steps are taken to ensure the city has clean drinking water. It will include stops at the upper reservoirs, dams, gatehouses, and the CWD field office.

When: Saturday, September 30, 2023 from 8:30 am to 4:00 pm. Rain date is Sunday, October 1st.

Where: The ride starts and ends at the Walter J. Sullivan Purification Facility at 250 Fresh Pond Parkway, and explores the Cambridge watershed, which includes the lands and reservoirs in Lincoln, Lexington, Weston, and Waltham.

How: Register here if you'd like to participate! All you need is a working bike, helmet, lunch, and water. If you would like to join but need a bike, Urban AdvenTours rents hybrid and road bikes that are suitable for the event (make sure to note “Cycle to the Source 2023” when you reserve a bike).
