Join Groundwork Lawrence, Rebecca Veilleux and Tennis Lilly, for a brisk hike through Lawrence’s “hidden jewel,” Den Rock Park. The park is a 120- acre wooded preserve that includes walking trails, a granite rock face, scenic overlooks, a beaver pond, and access to the Shawsheen River. Well behaved dogs on leashes are welcome. Wear comfortable walking/hiking shoes and bring water.
