Presque Isle State Park, a peninsula with seven miles of beaches and 14 miles of paved waterside trails is an Erie treasure. It draws approximately four million yearly visitors for every outdoor activity under the sun. Park visitors can swim, boat, fish, scuba dive, hike, bike, roller-skate and enjoy a great summer music series against the backdrop of beautiful Lake Erie sunsets. However, you might not be aware of the park’s many hidden treasures. The sandy peninsula provides a haven for migrating birds and the best place to bird watch. The park also reports the greatest numbers of endangered, threatened and rare species in the state. And just off its coast lie shipwrecks that tell stories of the area’s history. Park visitors can learn about these hidden gems during the Discover Presque Isle sponsored by the Presque Isle Partnership on July 29, 30 and 31. This year, PIP partnered with Pennsylvania Sea Grant to offer Hidden Treasures of Presque Isle. Read about the free activities on this week's NIE page.
