One of the most popular hiking areas in Maryland boasting great overlooks, challenging ascents and incredible rock formations (part of the ancient Appalachian Mountains that were formed 250 million years ago. Geologically speaking, these mountains are very old!). What kind of hiking mood are you in? Offering easy to strenuous hikes that can lead you to stunning vistas or more quiet experiences immersed in nature, numerous options are available. Some say hiking is just walking where it’s okay to pee. We actually say that, too. That certainly applies to Catoctin Mountain Park, where there’s adventure and beauty at every bend in the trail.
