Fall foliage is approaching peak in the Lehigh Valley, while areas north of the region have reached peak or are declining.
The state Department of Conservation and Natural Resources said in its weekly fall foliage report that Lehigh and Northampton counties are approaching peak color, while Carbon County is already there.
Monroe County is no longer at peak color, according to foresters, who said foliage is still nice, but declining. Nearby Bucks, Berks and Montgomery counties also are approaching peak color.
Fall color can be seen in all parts of southeastern Pennsylvania, and foresters said Nockamixon State Park in Upper Bucks County has a good view of the fall colors.
Foresters in Carbon County said many of the oaks there are approaching peak color, and northern parts of the county are not far behind. They recommend going to Penn Forest and Roaring Creek tracts, or Locust Lake and Hickory Run State parks to see good color.
Last week’s chilly nights kicked leaf color into high gear, and with more cool mornings in the 30s and 40s ahead, the display is only getting better! 🍁
This could be the peak week for fall foliage in much of the state.

Most of Monroe County is past peak color, but more urban areas, such as Stroudsburg and East Stroudsburg, should have attractive foliage, the report states. Southern Monroe County would be the best part of the county to see fall color, according to the DCNR.
Foresters recommend going to Big Pocono State Park, Delaware Water Gap National Recreation Area, the Appalachian Trail or any local parks to see the remaining color.
The Pocono Mountain Visitors Bureau said in its weekly report that sassafras and sumac are displaying bright crimson colors, while witch hazel, hickories and birch are starting to fade. Oaks are changing, adding color and texture to the edges of woodlands and fields, the report states.
Visitors should go to Penn Forest or Hickory Run State Park to see the foliage, the bureau said. Full color is at 60%, with 75% of the leaves still on trees, according to the report, which project next week for peak color.
