This week will be the ideal time to see foliage in the Lehigh Valley, according to experts.
Foliage in Lehigh and Northampton counties, as well as neighboring Bucks, Berks and Montgomery counties, will be peaking this week, the Department of Conservation and Natural Resources said in its weekly report.
Foresters said all southeastern Pennsylvania counties are full of “beautiful fall color,” with peak conditions prevailing. It can be seen everywhere in the district, the report stated.
North of the Lehigh Valley, in the Poconos, foliage is past peak, according to the DCNR. Still, foresters said good color could be seen along Route 209 in Monroe County, as well as on Blue Mountain.
The Pocono Mountain Visitors Bureau said in its weekly report that sassafras trees are putting on a “vibrant show” of crimson hues across Monroe and Carbon counties. Both are past peak color. The visitor’s bureau estimated the area was at 90% full color, with 60% of the leaves on the trees.
Cold nights last week helped push fall color farther south across Pennsylvania!
This week is still prime time to take in the beauty of Penn’s Woods — from the Piedmont forests in the southeast to the Allegheny Plateau out west!
