About Tall Pines
Tall Pines State Preserve in Hunterdon County protects a rare stand of mature forest in New Jersey’s rural western hills — the Hunterdon Plateau. The preserve’s towering tulip poplars, white oaks, and hemlocks represent some of the largest surviving old-growth timber in the state. Hunterdon County, with its horse farms, covered bridges, and stone walls, feels more like New England than metropolitan New Jersey.
Things to Do
Walking among mature and old-growth trees, birdwatching, nature photography, and experiencing preserved forest in New Jersey’s most rural county.
Plan Your Visit
Tall Pines State Preserve provides quiet walking trails through mature forest — no camping or developed facilities. The preserve connects to Hunterdon County’s extensive trail system and the adjacent Musconetcong River for canoeing and tubing. Nearby Clinton (the iconic Red Mill village) and Flemington (home of the Lindbergh baby trial) add historical interest. The preserve is free and open dawn to dusk year-round.
Nature & Wildlife
The mature forest canopy — tulip poplars reaching 100+ feet — supports pileated woodpeckers, barred owls, and wood thrushes. The understory features spicebush, witch hazel, and mountain laurel. Red foxes, gray foxes, and white-tailed deer inhabit the preserve. Spring ephemeral wildflowers (bloodroot, trilliums, Virginia bluebells) carpet the forest floor in April before the canopy leafs out. Box turtles are common along the trails.
Insider Tips
Old growth remnant: Tall Pines preserves some of NJ’s finest remaining old-growth forest — a rarity in the most densely populated state. Pro tip: NJ has 1,263 people per square mile — the densest state in America — making every acre of preserved forest precious. Forest fragments: NJ’s remaining forests are increasingly isolated fragments — connected corridors are essential for wildlife movement.
Best Time to Visit
Fall: Old-growth foliage. Spring: Wildflowers. Summer: Shaded forest. Year-round: Trail access.
Frequently Asked Questions
Why is old growth rare in NJ?
New Jersey has been intensively settled since the 1600s — nearly every acre was logged, farmed, or developed at some point. Old-growth forests (never cut) are exceedingly rare — perhaps 2,000 acres total in the entire state. These remnants contain trees 200-400+ years old and support species assemblages that second-growth forests lack. Tall Pines preserves a window into NJ’s pre-colonial landscape — irreplaceable living history.
Nearby state parks: If you have extra time, Penn State Forest is a short drive away, and Warren Grove Recreation Area is a short drive away.
