You’re standing on a pile of Tuscarora quartzite, the wind is whipping your hair into a bird’s nest, and suddenly someone screams, "Ospray, low at nine o'clock!" Your head snaps left. Just like that, you’re part of a tradition that’s been running since the Great Depression. Hawk Mountain Sanctuary in Kempton PA isn't just a place to go for a Saturday hike. Honestly, it’s the site of a literal revolution in how we look at predators.
It’s wild to think about now, but people used to come here just to shoot things. In the early 1930s, the "sport" was simple: wait for the raptors to catch the updrafts along the Kittatinny Ridge and open fire. Thousands of hawks died right where families now eat granola bars and look through Swarovski binoculars.
The shift happened because of Rosalie Edge. She was a suffragist and a total powerhouse who heard about the slaughter and decided to buy the mountain. That’s not a metaphor. She actually leased the property in 1934 and eventually bought it to stop the killing. It became the world’s first refuge for birds of prey.
The Kittatinny Ridge: Nature’s Highway
Why here? Why Kempton?
Basically, it's about the rocks. The Appalachian Mountains form this long, continuous spine. When the wind hits the side of the ridge, it creates these "updrafts." Think of it like an invisible elevator for birds. Instead of flapping their wings and burning precious calories, hawks, eagles, and falcons just lock their wings and glide.

They’re lazy. Or efficient. Depends on how you look at it.
During the peak migration months—mostly September through November—the North Lookout becomes a crowded hub of "hawk watchers." These are folks who can identify a Sharp-shinned Hawk from a Cooper's Hawk at five hundred yards just by the way the bird flicked its tail. It’s impressive. Sorta intimidating, too, if you’re just there with your phone camera.
If you visit in mid-September, you’re looking for Broad-winged Hawks. They travel in "kettles." A kettle is basically a swirling vortex of birds—sometimes hundreds of them—catching a thermal. It looks like black pepper spilled across the sky.
What to Expect When You Get to Kempton
The drive in is pure Pennsylvania Dutch Country. Rolling hills, red barns, and the smell of manure. It’s charming. When you pull into the sanctuary, you’ll start at the Visitor Center.
Wait. Before you bolt for the trails, check the chalkboard. They keep a daily tally of every bird spotted. 10 Sharpies. 2 Bald Eagles. 1 Merlin. It gives you a sense of what to keep your eyes peeled for.
The trails vary. The Lookout Trail is the most popular. It’s an easy-to-moderate climb if you take the Silhouette Trail (which is ADA accessible for a good portion), but it gets rocky. Real rocky. Pennsylvania isn't called "Rocksylvania" for nothing. You'll need actual shoes. No flip-flops.
The North Lookout Experience
This is the big one. It sits at about 1,500 feet. On a clear day, you can see the patchwork of farms in the Lehigh Valley stretching out forever.

There's a specific etiquette at the lookout. It’s quiet. People are scanning. When a bird is spotted, the "official counter" calls it out using a clock-face system. "Red-tail at two o'clock, high!"
If you're a newbie, don't be afraid to ask questions. Most of the people sitting on those rocks with $2,000 binoculars are dying to tell you the difference between a male and female Northern Harrier. It's their whole thing.
The Science Nobody Talks About
Hawk Mountain Sanctuary in Kempton PA is more than a viewpoint; it's a global research hub. They have one of the longest-running sets of migration data in existence.
This data is how we found out about the DDT crisis. Scientists noticed the numbers of Bald Eagles and Ospreys were cratering. Because the counts at Hawk Mountain were so consistent, they had the proof. They could say, "Look, the birds aren't coming back."
Today, they track things like:
- The timing of migration relative to climate change.
- The health of American Kestrel populations (which are unfortunately struggling).
- Vulture movements in Africa and South America.
They’ve trained hundreds of conservation trainees from all over the world. A biologist from Argentina might spend a season in Kempton learning how to trap and band hawks, then take those skills back home. It’s a pretty cool legacy for a little mountain in Berks County.

Beyond the Hawks: Year-Round Vibes
Most people only think of this place in the fall. That’s a mistake.
In the spring, the mountain is quiet and lush. The songbirds are moving through. You’ll see Scarlet Tanagers that look so red they seem fake.
Winter is for the hardcore. It’s cold. Brutally cold. But the view is unobstructed, and the Golden Eagles usually show up later in the season, around November and December. If you’ve never seen a Golden Eagle, they’re massive. They make a Red-tailed Hawk look like a pigeon.
River Rocks and Forest Trails
If you want to escape the crowds at the North Lookout, head down to the River of Rocks. It’s exactly what it sounds like. A giant boulder field leftover from the last ice age. You can’t see water, but you can sometimes hear it running deep underneath the stones. It’s eerie and beautiful.
The hike back up from the River of Rocks is a "stair-master" workout. You’ve been warned.
Real Talk: Practical Tips for Your Visit
- The Crowds: If you go on a Saturday in October, it’s going to be a zoo. Parking overflows. The trail feels like a parade. If you can swing a Tuesday morning, do it.
- The Gear: Bring a seat pad. Sitting on quartzite for three hours will numb your backside. Also, binoculars are non-negotiable. If you don't own any, you can rent them at the Visitor Center for a few bucks.
- The Food: There’s no cafeteria. Pack a sandwich. There’s a nice picnic area near the parking lot, but eating on the lookout is better. Just pack out your trash. Seriously.
- The Cost: There is a trail fee for non-members. It’s around $10 for adults. It goes directly to bird conservation, so don't be a cheapskate.
Is It Worth the Trip?
Honestly, yeah.
Even if you don't care about birds, the history of the place is heavy. You’re walking on ground that transitioned from a "killing field" to a sanctuary. That's a rare kind of victory in the world of conservation.
You'll leave with a stiff neck from looking up, but you'll also feel a bit more connected to the planet. There is something grounding about watching an animal travel 5,000 miles just because its DNA told it to.
Your Next Steps
- Check the Migration Forecast: Before you drive out, look at the HawkCount.org website. It shows the daily numbers for Hawk Mountain. If the wind is coming from the Northwest, that’s your signal to go. Northwest winds push the birds closer to the ridge.
- Download a Merlin: Get the Merlin Bird ID app on your phone. It has a "Sound ID" feature that’s basically Shazam for birds. It helps when you're in the wooded parts of the trail.
- Visit Eckville: If you’re hiking the Appalachian Trail (which passes right through the sanctuary), stop by the Eckville Shelter just down the road. It’s a famous spot for thru-hikers.
- Plan for the Weather: It is always at least 5 to 10 degrees colder on the lookout than it is in the parking lot. Layers are your best friend. Even if you’re sweating at the bottom, you’ll be shivering at the top once you sit still.
- Explore Kempton: After your hike, grab a bite in the town of Kempton or nearby Kutztown. The Kempton Hotel has that classic, no-frills PA vibe that fits a day spent in the woods.
