A 16-acre field of glacial boulders, a National Natural Landmark since 1967, sits at the heart of one of the largest state parks in the region — here's how to see it properly.
At nearly 16,000 acres, Hickory Run — established in 1945 — is one of the largest state parks in the Poconos, with more than 40 miles of trails threading through Carbon County forest and some of the region's best trout streams. Most visitors come for one feature specifically: the Boulder Field, a roughly 16-acre expanse of rock spanning almost 1,800 feet at its widest point, left behind by glacial activity more than 20,000 years ago and designated a National Natural Landmark in 1967 — one of only 27 such sites in Pennsylvania.
Walking the Boulder Field itself is slower and more physical than it looks in photos — the boulders are uneven and shift underfoot, so sturdy footwear and a bit of patience make a real difference. Beyond the field, Hawk Falls is a short, popular hike to a genuine waterfall, and the park's trout streams draw dedicated anglers well outside of peak tourist season.
Our own Boulder Field Trail hike listing leads directly to this same landmark, and the park sits just past our Big Boulder Lake destination — an easy add-on for guests already staying near Jack Frost or Big Boulder who want a genuinely different kind of afternoon than another lake day.
