If there's one thing most diners can agree on, aside from the fact that Erwin's Country Kitchen dishes up delicious German and American food, is they feel right at home at this cozy eatery in Trevose.

Don't expect modern decor or all the bells and whistles you might find at a chain restaurant. This quaint Pennsylvania restaurant exudes old-school charm - from the decor to the menu.

That case of wanderlust might draw you in, but the chill vibe and delicious food will likely be what brings you back again...and again.

Chances are you walked through the front door for an authentic German meal. Try one of the classics - Knockwurst with sauerkraut or schnitzel with German potato salad.

Liverwurst with onions, stuffed cabbage, and stuffed schnitzel may also be on the day's menu.

The menu at this cozy kitchen also features a variety of American classics - burgers and meatloaf, for example - so there's something for every taste.

Nestled within the 50,000-acre Quehanna Wild Area, the substantially smaller 975-acre Marion Brook Natural Area is perhaps best known for its white birch forest and elk population.

One of the best ways to explore this pristine natural area, the Marion Brooks Loop Trail meanders just over three miles and promises some of Pennsylvania's most stunning natural scenery.

While beautiful all year, the scenic hike proves particularly awe-inspiring during the peak of the fall foliage.

Despite its easy rating, the trail tends to be quite quiet, so chances are pretty good that you won't run into anyone else during your trek.

You might not run into any other hikers along this predominately flat path, but you likely will cross paths with local wildlife. The forest is home to elk, deer, turkey, and even bears.

Try to time your visit with the peek of the fall foliage, so you can drink in the rustic colors of the season.

Bring your camera, too.

Hikers give this picturesque hiking trail top marks for its ease and lack of elevation changes. Be prepared, though, as some spots can be overgrown.

It's dead quiet now, but once upon a time, this place was bustling.

Brownsville was a busy place at this time, with many people traveling through at any given time for an assortment of varied reasons.

The new hotel would have the capacity for 200 people, as well as a coffee shop and state-of-the-art parking area, as vehicles were growing in popularity and many guests needed a place to park for the night.

Later, the place was acquired by Earle Milner Hotels and leased out rooms at just four dollars per night. Once again, though, it was not to last.

Meanwhile, in the outside world, things weren't going much better for Brownsville.

Finally, during the 1990s, the building closed its doors for good. Today, the hotel sits quiet and alone in downtown Brownsville.

It's best to sit back and admire the work of those who do decide to take the risk and enter these places.

Every old, abandoned, crumbling building has a story to tell...

1. Lancaster

2. Bushkill Falls

3. Jim Thorpe

4. Hershey Park

5. Mister Ed’s Elephant Museum

6. Kinzua Bridge

7. Pocono Mountains

8. Pat’s or Geno’s?

9. Delaware Water Gap

10. 1,000 Steps Trail

11. Frank Lloyd Wright’s Fallingwater

12. D.G. Yuengling & Son, Inc. - Brewery, Museum and Gift Shop

14. Hawk Mountain Sanctuary

If you travel through the small town of Schuylkill Haven, you might drive right past Mac's Diner, a tiny roadside restaurant that easily fades into the background.

But then you'd miss out on a delicious meal at a restaurant that's been delighting locals since 1991. In the beginning, though, the tiny diner was known as Robin's Diner.

Few restaurants can stand the test of time without offering the full culinary experience, and that's just what Mac's Diner does. Guests praise the tiny restaurant for its scrumptious food, top-notch service, and affordable prices.

Snag a seat at the counter or one of the tables, but make sure you check out the board with the day's specials first.

You'll find all of the breakfast classics on the menu, but if you're really hungry, try the trash can omelet, which boasts five eggs.

Mac's serves some of the best comfort food around, so dig into such lunch favorites as chicken dumplings, tuna salad, or a burger.

While you'll likely fill up with the main course, you can probably squeeze a slice of fresh pie in for dessert, right? Check out the menu board for the day's offerings.

When you're craving the quiet of nature, make your way to Tyler State Park, which boasts 1,711 acres of sheer natural beauty - from wildflowers to a waterfall.

While the trail snags a moderate rating, most hikers agree that it's more on the easy side and is more than doable for kids.

One of the highlights of this winding trail is the wildflowers that add an extra pop of color to the landscape. The trail is predominately paved, although you'll face quite a few hills.

Plenty of surprises await along the trail that's home to Schofield Ford Covered Bridge, an enchanting piece of the past.

The unassuming exterior of Pudge's Steaks & Hoagies, tucked in a strip mall in Blue Bell, belies the delightfully delicious secret just beyond the front door.

Some of the biggest and best cheesesteak sandwiches in Pennsylvania wait just past the entrance. You can order to go, but can you really wait that long for that first scrumptious bite?

Diners give this hoagie shop glowing reviews with some crowning it "the place to go" for an authentic cheesesteak. It's even been voted the best cheesesteak sandwich in Philly.

Chances are pretty good that, even if you have a hearty appetite, you'll be leaving with leftovers. The cheesesteak hoagies, available in 12-inch and 20-inch, are just that big.

Go big, and opt for the 20-inch. Even if you're stuffed before that final bite, you'll have a snack for later.

If you're really hungry and a culinary daredevil, sign up for the cheesesteak challenge. You've got half an hour to eat a large cheesesteak and a tray of fries while washing it down with a large soft drink.

What if you're not in the mood for a cheesesteak? Pudge's serves a slew of favorites - hoagies, chicken sandwiches, and grilled sandwiches.

A good, old-fashioned burger and fries sometimes just hit the spot.

Or how about a classic deli sandwich? Roast beef, corned beef, and turkey are just a few tasty choices.

Prepare for an adventure and an epic challenge along the aptly named Elk Trail, a 17.2-mile path that rightfully earns a hard rating.

Winding its way through just a small section of Elk State Forest, the trail features a variety of terrain. Some sections even travel along the road.

If you're not up for trekking the entire path, which is estimated to take a little over seven hours, you can easily hike a few miles and turn back.

However, if you want to hike the entire trail, consider making it an overnight adventure. Backpacking is popular along this quiet trail.

Be prepared to deal with a variety of terrain as you meander through the forest and on the roads, most of which are gravel and dirt.

You'll also travel past flowing creeks and likely cross paths with more wildlife than people.

Keep an eye out for elk, deer, and porcupines.

For jaw-dropping views, consider setting off during the fall. Drink in the stunning colors of autumn and enjoy cooler temperatures.

Find more information on the official website of Elk State Forest. Or, stop by the Facebook page of this Pennsylvania forest.
