Go on a treasure hunt hike! Letterboxes are hidden all over our parks and Montgomery County Rec and Parks will guide you on a hike to find them using clues provided. Please register no later than 24 hours before the hike so they can contact you with the hike’s location and other important information. You will meet up with a naturalist who will provide you with the clues and send you on your way down the trail. Intended for ages 5 & Up.
