Where to Swim in Cook Forest, PA: A Local’s Guide
There is nothing quite like the feeling of cool river water on a warm summer afternoon in the woods. The Clarion River winds right through the middle of Cook Forest, and once the weather warms up, our guests want to know one thing above all else: where to swim in Cook Forest.
We are Michael and Amanda, and we have been welcoming guests to Hemlock Haven Retreats for over eight years. We grew up in this corner of Pennsylvania, and we raise our two kids here alongside our two cats, dog, ducks, and chickens. Swimming season is one of our favorite parts of the year, and we want to make sure you find the right spot for your group.
This guide covers every good swimming option we know of, from wild river spots to family-friendly pools and a real sandy beach nearby. Whether you are traveling with kids, dogs, a partner, or just yourself and a book, you will find something here.
Swimming in Cook Forest at a Glance
Before we get into the specific spots, a few important things to know about swimming in Cook Forest, PA:
- There is no lifeguarded swimming beach inside Cook Forest State Park itself. Swimming happens in the Clarion River at informal riverbank spots and hand-carry launches.
- The Clarion River through Cook Forest is a gentle Class I river, meaning slow to moderate current with easy riffles. It is beginner-friendly and family-friendly in most conditions.
- The best time to swim is late May through September, when both air and water are warm enough for a real dip.
- For a true sandy beach, head to Clear Creek State Park, about 11 miles from Cook Forest.
- If you want a chlorinated pool, Cook Forest Fun Park and several campgrounds have you covered.
Now let us walk through the best places to swim in Cook Forest, one by one.
Swimming in the Clarion River
The Clarion River is the heart of Cook Forest, and for us it is the number one answer when guests ask where to swim. A scenic 13-mile stretch runs right through the state park, and it is designated a Wild and Scenic Waterway. The water is generally calm, clear, and cool. Sandbars and gentle shallows show up along the banks, and there are plenty of quiet pull-offs where you can spread out a towel and float away an afternoon.
Two important reminders:
- No section of the river is lifeguarded. Kids should always wear life jackets.
- Water levels change with the weather. Call the park office if it has rained hard the day before, and check current gauge data before you head down.

Nearby Beaches and Lakes to Swim
If you want a proper sandy beach or a full lake experience, you have two excellent options within a short drive of Cook Forest.
Clear Creek State Park
This is our top recommendation when guests want a real beach day. Clear Creek is just 11 miles from Cook Forest, and the Clarion River connects the two parks. The park has a dedicated swimming area, a sandy pond, and a smaller-feeling atmosphere than Cook Forest. Little kids can splash in Clear Creek itself, and older swimmers can venture into the Clarion River access here.

Pools and Family-Friendly Swim Spots in Cook Forest
Some days you just want chlorinated, predictable water. We get it. These options are especially useful with young children or on days when the river is running high after a storm.
Cook Forest Fun Park
This is our family go-to when the kids want more than just floating. Cook Forest Fun Park has a big heated pool, plus go-karts, bumper boats, and 18 holes of mini golf with waterfalls and koi ponds. It is a full-day family destination right on PA-36 in Leeper, and it is a short drive from most of our cabins.

Cook Forest Sawmill Center for the Arts (Rainy-Day Alternative)
Not a swim spot, but worth mentioning because plans change. When the river is unswimmable after a big rain, the Sawmill Center is a wonderful indoor plan B. It sits right in Cooksburg and hosts craft shows, chainsaw carving demonstrations, and small performances. It is easy to pair with a picnic lunch and a light hike.

Our Local Tips for a Safe, Fun Swim Day
A few things we tell every guest before they head to the river:
- Wear water shoes. The Clarion has slick, smooth rocks underfoot. Water shoes save toes and dignity.
- Bring a dry bag. Phones and car keys do not swim. A cheap dry bag is worth its weight in gold on a tubing trip.
- Check the gauge. Before you launch, look up the Clarion River gauge or call the park office. Below 2 feet is too shallow for a fun tube. Above 6 feet is often too fast.
- Pack more water than you think. The sun over the river is deceiving. Bring double the water you think you need, plus snacks that hold up in the heat.
- Life jackets for kids, always. No exceptions, no matter how strong a swimmer they are.
- Time your day. For a full float from Pale Whale, start by mid-morning. Trips can be a few hours long, and the outfitter has firm cutoff times.
