Know Before You Go

If visiting in late spring or summer, please make sure to bring bug repellant as mosquitoes and black flies can be out. Wearing long pants and long sleeves can also help with not getting bite and give sun protection. Hats and sunblock are good for sun protection too. As always, please stay on trail; this will also help prevent you from picking up ticks or touching poison ivy. If going on a long hike it is always a good idea to bring water and snacks, and pack your cell phone in case you get lost. Please review rules and regulations, found here: http://www.fws.gov/refuge/Assabet_River/visit/rules_and_regulations.html before visiting.
