Please join members of 350 Mass Waltham and the Waltham Land Trust as we clean up the Charles River Greenway. This area is a beautiful walking and biking path, and since it does not have any trashcans, can get dirty from time to time.

Join us for a 1.5-mile leisurely walk on the Pondside Walkway, starting at 1:30pm, to learn about ongoing stewardship efforts to protect Hardy Pond, enjoying sights of nature along the way. We’ll end at the Land Trust’s Lakeview Preserve at 3:00pm to check out the new land we purchased in June.

Stretch and hold in a field at Met State with Jeanne Kelly, a popular yoga instructor at the Waltham YMCA. To get the WLT Member pricing, login when registering for the event. Rain date is October 10th.  

Celebrate Halloween with a spooktacular day on the trails! The Waltham Land Trust invites you to celebrate Halloween in the best way possible — moving through nature, in costume (if it’s safe to run in), and helping protect Waltham’s beautiful open spaces.

Since 2013, our Western Greenway 5K has brought together people of all ages to enjoy 3.1 miles of gorgeous fall scenery.

NEW for 2025! 🦇
Before the main race kicks off, kids ages 10 and under can join our 50-yard Monster Dash at 11:30 am — a quick, fun sprint where every child gets a small treat for participating. Free for children who attend with an adult running the 5K, $5 suggested donation otherwise. Perfect for little ghosts and goblins who want in on the action! 

A Walk in the Park: A Guide to Plant Communities at Prospect Hill Park, Waltham, Massachusetts

This book is a nature guide for the non-scientist interested in learning about plants and basic ecology.

Get outside and on the trails! Waltham and its neighboring communities offer numerous well-marked and maintained trails through a variety of beautiful natural landscapes.

The WLT has produced a series of Guide to Open Spaces available as a free resource on our website.

Founded in 1999, the Waltham Land Trust’s mission is to create a legacy of land conservation in Waltham by promoting, protecting, restoring, and acquiring open space with a community of volunteers and a small staff that operates with mutual respect and goodwill towards each other

Protecting and preserving takes time, energy and your support. Volunteers build trails and maintain them. Your support helps provide the tools and supplies.
