5 Best Natural Wonders To Visit In Maryland This Year
Often known for its rich history as the birthplace of the US national anthem and one of the first to be settled by Europeans, the Mid-Atlantic state of Maryland abounds with opportunity. Beyond the tales of old, this state boasts a scenic coastal location and a stretch of Appalachian Mountains that is full of life. From the Potomac River to the Chesapeake Bay, there is no end to the outdoor charm, opening up plenty of places for nature lovers to visit.
Hiking, biking, camping, swimming, and boating are just some of the many ways you can take in the diverse topography of the Old Line State. The state also has unique sights like the Crystal Grottoes Caverns, underground caves perfect for a mysterious outing. So, to help you find the best places to visit this year, discover five of the best natural wonders in Maryland.
Assateague Island National Seashore
Probably one of the most popular outdoor destinations in the state, the Assateague Island National Seashore is located along Assateague Island and the Atlantic Ocean. Part of the National Park Service, it is the largest natural barrier island ecosystem in the region, spanning 37 miles with over 41,000 acres of protected land. In 2022, the landmark saw over two million visitors, and there is a good reason for this. Activities are plentiful and of all types. Those who want to spend time near the water can go surf fishing in the saltwater, but you will require a saltwater license. On the other hand, crabbing is just as popular, while kids can head out on ranger-guided programs to learn about the important ecosystem.
For an experience inland, hiking and biking are the go-to, with 37 miles of open sand lined with paved and unpaved trails. The Life of the Forest trail is a quaint wooded trail that stretches for half a mile, where one can explore the coastal forests and abundant wildlife. Among the many animals that live here, such as brown pelicans and brant geese, horses are the star of the show, as this area is home to the rare Chincoteague ponies. People from all over come to see them, and those who bring their own horse can also ride alongside them.
With so much to see and do, visitors will be glad to know that the park is open year-round, 24 hours a day. People can camp at one of many designated campgrounds, like the Bayside Drive-in, which has tent, trailer, and RV sites, or the Horse Camp, offering space for horses to sleep. Assateague Island National Seashore also has a visitor center open in the morning, where one can learn about the island, check out the aquariums, and book one of the many tours. While some parts do close due to weather and climate conditions, June to October is the best time to visit, as there are fewer bugs and the weather begins to cool off for a pleasant environment. Last but not least, a seven-day pass to the park costs $25, although paying for a vehicle will cover entry for all passengers.
Green Ridge State Forest
While it may not have as much water as Assateague Island, Green Ridge State Forest in Western Maryland abounds with verdant greenery. Spanning 48,000 acres, this state forest is a treasure trove of flora and fauna, where nature lovers can roam through troves of pine, dogwood, and other plants. Hiking is the best way to experience this forest, thanks to its 80+ miles of open trails. Those looking for an easy outing can opt for the 50-yard-long Scenic Overlook Trail, while the 9-mile-long Long Pond Trail warrants a challenge that only professionals should attempt. With mountain biking and horseback riding also allowed, one should start a journey by getting a map at the Green Ridge Headquarters. Even if you are not one to exert yourself, there is a self-guided driving tour for an easy way to take it all in.
Those who want to spend the night here also have plenty of options to choose from, whether in the midst of trees or along the Potomac River. Out of around 100 designated primitive campgrounds, the Ridge Rider Campground puts you close to the river, and there is only a $10 per night permit fee for camping. However, as these are primitive sites, always keep your food hidden from local wildlife like coyotes, foxes, and raccoons. No matter how you decide to spend your time in the Green Ridge State Forest, entry costs are free, and the park is open throughout the year. The best time to visit is during the fall, as the colors change to hues of gold and brown, and the weather is perfect for hiking.
Crystal Grottoes Cavern
Away from the light of the sun and the greenery on land, Crystal Grottoes is the only show cave in Maryland. Hidden beneath the ground, this series of caverns was discovered in 1920 by a quarrying operation. By 1922, it was opened to the public, and a larger Lake Room was discovered a few decades later. The cave was subsequently mapped in 1968, uncovering around half a mile of underground passages. As of 2025, around 900 feet are open to tour, and entry costs $23 for adults from 10 am to 5 pm.
Once inside, the cave opens up a new world to discover with tons of unique formations such as stalactites, flowstone, and columns. As you move deeper in, red and brown clay fill the rooms, and there is even a lake that is fed by drip water. The largest known room is the Blanket Room, which is 30 feet long and 20 feet wide, opening up a massive display of stalactites on its ceiling. The entire tour takes around forty minutes, and it is a once-in-a-lifetime experience easily accessible near Boonsboro. Once out of the cave, tourists can also spend time sifting through sand for gems at the Gem Mill experience or learning about the cave at the facility above ground. Tours are only open for certain periods throughout the year, such as from April to November and December to March, so check their website to be sure!
Catoctin Mountain Park
Far above the depths of Crystal Grottoes, Catoctin Mountain Park takes tourists to higher elevations in Maryland. This park is part of the Catoctin Mountain Range, a sub-range of the Blue Ridge Mountains. Covering an area of over 6,000 acres, it is full of unique rock formations and towering peaks. Some of the most popular are Chimney Rock and Wolf Rock, both reaching a height of over 1,400 feet with scenic forest overlooks. The best way to explore the park is via the 25-mile trail system that covers most major landmarks. Most beginners can head out along the 1.3-mile Deerfield Nature Trail Loop, running along water with minimal elevation changes.
Apart from hiking, the park is also home to around six miles of horse trails, open for public horseback riding. These trails are closed during colder months for preservation. For tourists who want to spend the night among the mountains, there are three main campgrounds: Camp Misty Mount, Camp Round Meadow, and Camp Greentop. They each have space for dozens of people, and Round Meadow even has four heated dorms for larger groups. Add on other activities like fishing, wildlife watching, and picnicking, and the best time to visit this Maryland park is during spring or fall, when the calm weather is ideal for exploring the expanse.
Swallow Falls State Park
The star of the show in Swallow Falls State Park is a waterfall, but not Swallow Falls. The park is home to Muddy Creek Falls, Maryland’s highest free-falling waterfall, which plunges 53 feet over ancient bedrock into a spray of mist and cool air. Surrounding this cascade is a landscape carved by time, with rugged rocks, mossy boulders, and towering hemlock trees that have stood for centuries. The Youghiogheny River also winds through the park, creating smaller waterfalls like Swallow Falls and Tolliver Falls, each offering a tranquil setting for reflection or photography.
Visitors will find nearly two miles of scenic hiking trails that connect the waterfalls, making it easy to explore the highlights in just an afternoon. The trail winds along the river, through old-growth forest, and past natural stone outcroppings that reveal the park’s geologic past. For those who want to extend their stay, the campground provides 25 tent and 65 trailer sites surrounded by peaceful woodland, and picnicking areas let you settle in for a leisurely day beside the river. Wildlife such as deer, black bear, and countless bird species add to the sense of being deep in nature. With its dramatic falls and quiet forest trails, the park is best enjoyed in late spring through autumn, when the water levels are steady and the colors of the forest frame every view.
