The Lollipop Cruise is a good choice. 35 minutes from Natrona Heights in South Pittsburgh near Station Square. Pumpkin Picking Farm 15 minutes north of Natrona Heights, October. Todd Sanctuary Another Audubon Society delight. Many trail to hike.
Pond has peepers in the Spring.
15 minutes north, in Sarver, across from the 356 Cinema. A three mile hike, steep hills and a fantastic view of the river from a bluff overlooking Freeport. Might be a bit muddy if it has rained a lot recently. Ten minutes north. About one hour west.
