Cancellations due to COVID-19

*Due to COVID-19, all WLT events through April 30, 2020 have been cancelled. Stay tuned for updates. We will do our best to continue WLT's mission during this challenging time while acknowledging that Waltham's Public Officials must focus on public health and safety. We encourage you to get out and enjoy Waltham's green space while the gym is closed. Please maintain a safe distance of at least six feet from others and access maps and other information from our website, rather than trail kiosks, to minimize contact. We are all in this together!

Annual Charles River Cleanup - CANCELLED DUE TO COVID19

Update as of 3/24/2020 - Thank you to everyone that registered to help with the Charles River Cleanup. Unfortunately, due to COVID19 we have had to cancel the cleanup to avoid bringing us all together at this risky time. Stay safe!

Recognized by American Rivers as one of the largest river clean-ups in the country, the Charles River Clean-up will host thousands of volunteers in the Charles River Watershed to help remove litter and clean-up our waterways. Your support will make a huge impact on the river's health!

Open space needs your help

Protecting and preserving takes time, energy and your support.

Please consider a donation to help protect and preserve open space in Waltham.

Thank you!
