Western Greenway 5K and 1st ever Monster Dash for Kids! 10/26/2025 at 12:00pm (11:30am for Monster Dash)
October 28, 2025
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!

Over 60 nature lovers of all ages came to Christ Church for a program with Rick Roth the Snake Man and the Cape Ann Vernal Pool Team . We were introduced to many snakes found in New England and the world. Members of the team walked through the audience with them so everyone could see up close and take photos. Afterwards, brave people who wanted to hold the legless reptiles were given that opportunity. Many thanks to the Waltham Cultural Council for supporting this event!
