Very pleasant and convenient State Park near Pittsburgh. Miles and miles of wooded hiking trails, a campground and a big lake with boat rentals and a family friendly swimming beach with restrooms and concessions. No lifeguards but the swimming area is roped off, the bottom is mostly sandy and doesn't get much more than 5' deep inside the ropes. Shady spots for blankets and picnic tables. OK to grill. No dogs on the beach or in the water.
