Once every 2-3 years my family likes to get together for a family picnic and fun day at Colonel Denning. We typically do it in late spring or early summer, before it gets too hot. You'll find covered picnic pavilions at the park that are free to use, on a first-come basis, so you'll want to get there early if you plan on using one. You'll also find numerous charcoal grills that you can use if you plan on grilling out.
You can use a kayak or non-motorize canoe in the lake with appropriate registration and permits. You will have to "hand" launch them and carry them from the parking area over to the launch area. Please be respectful of other boaters who are out on the water too. Remember, everyone is there to have a good time!
If you enjoy hiking, you'll find two miles of marked trails for you to enjoy and a few of the trails will join up with trails that are within the Tuscarora State Forest. You can visit the park's office for a trail map if you're interested in doing some hiking. I would say that most trails are "moderate" hiking trails, so make sure that everyone in your hiking party is in decent health. You'll want to take plenty of bottled water along with you.
Every time we visit Colonel Denning State Park in Newville Pennsylvania, we have a great time. When visiting, you'll want to plan ahead, check the weather reports and take enough supplies along with you.
