Blue Hole in Forbes State Forest is a scenic Pennsylvania trail featuring a brilliant blue swimming hole and picturesque views.

Sometimes we hike for its sheer joy, to drink in the gorgeous scenery and the fresh air, connect with nature, and come face-to-face with wildlife. Other times, our hikes have a purpose or a destination, like visiting a hidden waterfall or making our way to a gorgeous Pennsylvania swimming hole. The Blue Hole in Forbes State Forest near Somerset is one such destination that those with a sense of adventure love finding. Although absolutely perfect in the summer, this scenic Pennsylvania trail is well worth following any time of the year, even just for a glimpse of the breathtaking blue hole that awaits. This is the kind of hidden gem Pennsylvania swimming hole that locals would rather keep to themselves.

Discover Blue Hole, an Underrated Natural Wonder

Forbes State Forest is a popular year-round destination. The 60,000-acre playground stretches across several counties in southwestern Pennsylvania, including Fayette, Somerset, and Westmoreland Counties, and is home to the state’s highest point, Mount Davis, at 3,213 feet. With over 300 miles of multi-use trails, this playground is a wonderful place for hiking, mountain biking, and horseback riding. Other popular activities include fishing, backpacking, wildlife viewing, skiing, and more. The forest is brimming with natural wonders, and it’s the kind of destination that feels miles away from the world. And while there are many reasons to visit this underrated hidden gem in Pennsylvania, the Blue Hole tops the list for me.

Even if you're not hiking in the summer, you'll absolutely love the scenery - especially the brilliant blue swimming hole - that awaits on the three-mile Cole Run Trail. Once you’ve followed the trail to Blue Hole Creek, I bet you’ll want to explore a little more. You can easily create your own adventure here. Earning a moderate rating on AllTrails, the picturesque path wanders through Forbes State Forest in Somerset and is particularly popular for one natural wonder – the Blue Hole.

Expect to spend at least 1.25 hours on the trail, and even more time if you plan to hang out at this swimming hole in Pennsylvania. Dogs are allowed on this scenic Somerset PA hiking trail, but make sure you keep your pooch on a leash. It wouldn’t be a bad idea to have an offline map handy for longer trails like this one. You never know when you will need it.

Very early in the trail, you'll come to another gorgeous natural wonder: Cole Run Falls. The photo-worthy cascade tumbles down 15 feet. If you don't have the energy for the entire trail, the trek to the waterfall is short and sweet. Hearing water flow in nature is always a relaxing experience, don’t you agree? The falls cascade over multiple rocks, and it’s a great backdrop for nature photography. So, you definitely don’t want to forget your camera on this unique trail in Forbes State Forest.

If you keep going, you'll travel alongside Blue Hole Creek. Expect some challenges, including rocky terrain, steep climbs, and slippery spots. Some hikers recommend bringing trekking poles, while others say a sturdy pair of shoes will do just fine. Keep an eye out, too, for roots jutting out of the ground.

What to Know Before Visiting Blue Hole in Pennsylvania

Cole Run Trail is moderately challenging and not very well marked, so keep that in mind. If you're hiking in the summer, bring along your swimming gear, a pair of water shoes, and plenty of water. Be aware that the swimming hole can get quite crowded, not to mention that it’s deep and can be dangerous, so take care when swimming, especially if you bring kids along. For many, the highlight of this Pennsylvania hiking trail is the shimmering blue (yes, it really looks blue) swimming hole known as Blue Hole. You'll definitely want to spend some time taking it all in.

Summer is the most popular time to visit, and you probably won't find as much foot traffic in the winter, when it can get pretty icy. Fall is especially pretty when the leaves change colors, surrounded by the gorgeous natural wonders inside the forest.

The park is open 24 hours a day, and there is no entrance fee, so you can spend as much time as you’d like soaking up all the beauty. And when you’re done, be sure to carve out time to visit the nearby town of Somerset. Here, you’ll find antique shops, great restaurants, and covered bridges. It’s a wonderful destination for a day trip in Pennsylvania, especially during the fall.

Before you plan your trip, I suggest visiting the Forbes State Forest website for more information. You can find details about camping, backpacking, hunting, scenic drives, and more.

Please take extra caution when swimming in the creek. The Pennsylvania Department of Environmental Protection has investigated lead contamination here and advises not to drink the water.

This peaceful Oklahoma lake has a cascading waterfall hiding just below the dam

The waterfall is easy to miss. It sits below the dam, hidden from the main view of the lake. Most people never walk far enough to see it. The trail is short and flat, and the payoff is a steady cascade of water that drops into a clear pool. Cool mist hits your face, and the sound of falling water fills the air. You can stand at the base or find a spot on the rocks and just watch. The lake stretches out behind you, calm and still, but the real...
