The Main Event: Gettysburg
The undisputed crown jewel of this route is Gettysburg National Military Park. Driving into town via Route 15 feels like entering a living museum. Between the sprawling battlefields, the high density of haunted taverns, and the towering monuments, it’s the definition of a "must-see" tourist destination.
Beyond the Battlefield
Once you’ve paid your respects at the site of the Gettysburg Address, Route 15 transitions into a beautiful riverside cruise.
- The Susquehanna Views: North of Harrisburg, the highway hugs the Susquehanna River, offering wide-angle views of the water and the massive stone arches of the Rockville Bridge—the longest stone masonry arch railroad bridge in the world.
- Selinsgrove & Lewisburg: These charming river towns offer a break from the history-heavy start of the trip with vibrant downtowns, craft breweries, and the gothic architecture of Bucknell University.
- Clyde Peeling’s Reptiland: For a complete change of pace, this world-class zoo right off the highway is a classic PA roadside staple that’s been drawing tourists for decades.
Why It’s "Touristy" (In a Good Way)
Route 15 strikes a perfect balance. You get the heavy-hitting educational sites of Adams County, the political energy of the state capital, and the tranquil, rural beauty of the Pennsylvania heartland—all without the aggressive lane-weaving of the turnpike.
