Alum Creek State Park is the big-water reunion spot for Columbus families - a 3,387-acre reservoir with nearly 3,000 feet of sandy beach, sitting barely 30 minutes north of downtown. For a metro area of two million people, that proximity changes the math: the grandparents can sleep in their own beds and still make the 10 AM group photo, the cousins flying into CMH are on the sand within 40 minutes of baggage claim, and nobody has to choose between a 'real' lake weekend and a drivable one. Alum Creek is both.
The lake is the main event. Built by the Army Corps of Engineers in 1974 and run as a state park across 4,630 acres of surrounding land, Alum Creek Lake allows unlimited-horsepower boating - skiing, tubing, and pontoon flotillas are all on the menu - and the full-service marina rents pontoons, kayaks, and paddleboards by the hour or day. The New Galena beach is one of the largest inland beaches in Ohio, a genuine crescent of sand with room for a 60-person reunion to stake canopies without touching the next family's territory. Anglers work the flooded timber and shale banks for saugeye, crappie, muskie, and largemouth bass, and the tailwater below the dam is a local secret for the early-morning crew.
Off the water, Alum Creek carries more variety than most Ohio parks: a mountain-bike trail system that riders rate among the best in central Ohio, roughly 38 miles of bridle trails with a dedicated horseman's camp, hiking loops under shale bluffs, a disc golf course, and one of the largest dog parks in the state - a four-acre beachfront run where the family dogs get their own swim. The 286-site campground with electric hookups anchors the stay-overnight wing, and picnic shelters near the beach reserve cheaply through reserveohio.com.
The surrounding area seals it for multi-generational groups. The Columbus Zoo and Zoombezi Bay water park are 20 minutes west, Olentangy Indian Caverns is practically next door, and the historic county seat of Delaware - restaurants, groceries, a classic small-town main street - is 15 minutes away. Like every Ohio state park, entry is free: beach, trails, shelters, and boat ramps cost nothing, so the reunion budget goes to pontoons and the cookout. For a family scattered across central Ohio that wants a lake weekend without a long haul, Alum Creek is the obvious first call.

Official source ↗Ski, tube & wakeboard the open-zone water

Good for
- Columbus-area families - a true big-lake weekend 30 minutes from downtown
- Boating and watersports crews - unlimited-horsepower lake with marina rentals
- Day-trip-plus-campout hybrids - locals commute, out-of-towners camp or hotel nearby
- Dog-owning families - a four-acre beachfront dog park built for the pack
- Budget-first groups - free entry, free beach, cheap shelter reservations
Practical logistics
- Closest Airports
- Columbus (CMH) about 35-40 min via I-270 and US-23. Rickenbacker (LCK) for some budget carriers, about 50 min. The park straddles US-23 and I-71 corridors north of Columbus.
- Drive Times
- Downtown Columbus 30 min · Polaris/Westerville 15-20 min · Delaware 15 min · Marion 40 min · Mansfield 1 hr · Dayton 1.5 hr · Cleveland 2 hr. Exit US-23 at Lewis Center or Cheshire Road.
- Group Lodging
- The 286-site campground (mostly electric, with showers and a camp store) is the on-site anchor - reserve contiguous sites via reserveohio.com. No lodge or cabins in the park, so mixed groups combine camping with the dense hotel cluster at Polaris/Lewis Center 10-15 minutes south.
- Rental Companies
- Vrbo/Airbnb list lake-area houses around Galena, Sunbury, and Delaware. Alum Creek Marina handles pontoon, kayak, and paddleboard rentals - book summer Saturdays weeks ahead. Hotel room blocks at Polaris are easy to arrange year-round.
- House Size
- Lake-area rentals for 8-12 run roughly $200-400/night; larger Delaware-County farmhouses for 12-16 run $350-600/night. Many Alum Creek reunions skip lodging entirely - locals drive in and the out-of-town wing camps or takes Polaris hotels at $100-160/night.
- Peak Season
- Memorial Day-Labor Day. Summer Saturdays fill the beach parking by late morning and the marina pontoon fleet sells out - arrive early and reserve boats ahead. Campground weekends book months out.
- Shoulder Season
- September is the sweet spot: warm water, empty sand, easy shelter availability. May brings wildflowers and pre-crowd fishing. October foliage over the shale bluffs is quietly spectacular.
- Restaurants
- Seasonal concessions at the beach and marina; full restaurant and grocery coverage 10-15 minutes away in Lewis Center, Polaris, and downtown Delaware - including big-group-friendly pizza and BBQ carryout for shelter cookouts.
- Kid Friendly
- Extremely - a giant sandy beach, rentable paddleboards, easy flat trails, disc golf, a dog park, and the Columbus Zoo 20 minutes away. Everything is close together, so naps and snack runs are painless.
- Accessibility
- Beach and marina areas have accessible parking and paved approaches; several picnic shelters and campground facilities are accessible. Shoreline trails are mostly flat; check with the park office for the smoothest routes.
- Weather Window
- June-August is beach weather (mid-80s°F, humid); the lake swims well June-September. Spring is green and mild but the water stays cold into early June. October is crisp foliage season; winter is quiet and cold.
- Park Fee
- Free - no entrance or parking fee at any Ohio state park. Beach, trails, boat ramps, dog park, and picnic areas cost nothing; you pay only for camping, boat rentals, and shelter reservations.

When to go
Mid-June through August is the full lake season - beach concessions open, marina fleet in the water, warm evenings for shelter cookouts - with the caveat that summer Saturdays are busy because two million people live 30 minutes away. Aim the all-family beach day at a Sunday or weekday if you can. September keeps the warm water and returns the sand to you. October wraps the shale bluffs in color for the best group-photo backdrop of the year, and the Columbus Zoo's holiday Wildlights makes even a winter mini-reunion work.
Best for your group size
Small group · 10–25
Groups of 10-25: one reserved beach shelter plus a pontoon covers the whole weekend - locals drive in, out-of-towners grab a lake-area rental or a Polaris hotel.
Medium group · 25–60
Groups of 25-60: reserve the largest shelter near New Galena beach, block a campground loop for the tent wing, and rent 3-4 pontoons. Add a zoo day as the second anchor.
Large group · 60+
Groups of 60+: combine multiple shelters or an off-peak weekday, a full campground loop, and hotel blocks at Polaris. For an indoor banquet night, Delaware County event spaces are 15 minutes away.

Reunion organizer tips
Reserve a beach-area picnic shelter through reserveohio.com the moment your date is set - shelters near New Galena beach are the natural HQ and summer Saturdays go fast.
Book pontoons at the marina 3-4 weeks ahead for summer weekends. One boat per 8-10 relatives, with a designated skipper per household, makes the lake day run itself.
Use the local-family advantage: let Columbus relatives host the out-of-towners or block rooms at Polaris hotels 10 minutes south, and treat the park as the daytime basecamp.
Reserve campground sites in one loop for the camping wing - contiguous sites turn the campground into a private family cul-de-sac with a shared fire ring.
Arrive before 10 AM on summer Saturdays. Beach parking fills late morning; an early start locks in the shady tables and the good stretch of sand.
Split the morning: mountain bikers hit the trail system, anglers work the saugeye banks, and the grandparents take the flat shoreline walk - everyone converges at the shelter for lunch.
Bring the dogs - the four-acre beachfront dog park is free and gives the family pack its own swim while the humans hold the cookout.
Schedule the Columbus Zoo or Zoombezi Bay as the second-day anchor - group tickets are cheaper booked ahead, and it doubles as the rain plan.
Do the grocery run at Lewis Center or Delaware on the way in - both are 10-15 minutes out, and nobody wants to leave once the canopies are up.
Stage the group photo on the beach an hour before sunset - the light comes across the widest part of the lake and flatters every generation.
Assign a cousin to gem mining duty at Olentangy Indian Caverns - the 10-minute side trip is the perfect pressure valve for kids who have hit their beach limit.
Run the whole weekend in Reunly - shelter and campsite reservations, pontoon assignments by household, the zoo-ticket headcount, and cost splits in one shared plan everyone actually reads.

Frequently asked
How far is Alum Creek State Park from Columbus?

Does Alum Creek State Park charge an entrance fee?
No - Ohio state parks are free to enter with free parking. The beach, trails, boat ramps, and dog park cost nothing; you pay only for camping, boat rentals, and reserved shelters.

The New Galena beach runs nearly 3,000 feet - one of the largest inland beaches in Ohio - with seasonal concessions and plenty of room for a reunion-sized group to spread out.
Can you rent boats at Alum Creek?
Yes - the full-service marina rents pontoons, kayaks, and paddleboards in season. The lake allows unlimited-horsepower boating, so skiing and tubing are on the menu. Reserve pontoons well ahead for summer weekends.
Is there a lodge or cabins at Alum Creek State Park?
No lodge or cabins - the on-site option is the 286-site campground (reserveohio.com). Most reunions pair camping with the hotel cluster at Polaris/Lewis Center 10-15 minutes south or lake-area vacation rentals.
What fish are in Alum Creek Lake?
Saugeye, crappie, muskie, largemouth and smallmouth bass, and catfish. The flooded timber and shale banks are productive, and the tailwater below the dam is a favorite early-morning spot.
Is Alum Creek good for kids?
Very - a huge sandy beach, flat shoreline trails, disc golf, a beachfront dog park, and gentle paddling coves, with the Columbus Zoo, Zoombezi Bay, and Olentangy Indian Caverns all within 20 minutes for side trips.
How crowded does Alum Creek get in summer?
Summer Saturdays are the busiest of any Ohio state park beach because Columbus is 30 minutes away - parking can fill by late morning. Arrive early, or aim the big beach day at a Sunday or weekday for a much calmer scene.
