Step-by-Step Guide

Step 1: Confirm Swimming Season and Hours

Swimming at Alum Creek State Park is not available year-round. The designated swimming beach operates seasonally, typically from late May through early September, depending on weather and staffing. Hours are generally from 11:00 a.m. to 7:00 p.m., but these can vary slightly from year to year. Always verify the current schedule before heading out.

Visit the official Ohio Department of Natural Resources (ODNR) Alum Creek State Park page or call the park office directly. Avoid assuming the beach is open—unannounced closures due to algae blooms, high bacteria levels, or staffing shortages are common. Checking ahead saves time and prevents disappointment.

Step 2: Choose the Right Beach Area

Alum Creek State Park features one main swimming beach, located near the Alum Creek Lake Dam. This area is the only designated swimming zone within the park and is clearly marked with signage and buoys. Do not attempt to swim elsewhere—other areas of the lake are off-limits for safety and environmental reasons.

The swimming beach is divided into two zones: a shallow wading area for children and a deeper swimming zone for adults and older kids. Lifeguards are stationed during operating hours, but their coverage is limited to the designated swim area. Always stay within the buoyed zone to remain under supervision and avoid submerged hazards like rocks, stumps, or strong currents.

Step 3: Arrive Early to Secure Parking and Spots

On weekends and holidays, especially during heat waves, the parking lot near the swimming beach fills quickly. Arriving before 9:00 a.m. ensures you get a spot and avoid the midday crowds. There are over 300 parking spaces available, but overflow parking may be directed to nearby lots during peak times.

Consider using the park’s main entrance off State Route 161 and following signs to the Day Use Area. Parking is free for Ohio residents with a valid state park pass or $8 per vehicle for non-residents. Payment can be made via cash or card at the automated kiosks near the entrance.

Step 4: Prepare Your Gear

Bring only what you need—Alum Creek’s beach area has limited amenities. Essential items include:

• Swimsuit – Wear a well-fitting, chlorine-resistant swimsuit. Avoid loose clothing that can become entangled in water or drag you down.
• Towel and changing robe – Bring a quick-dry towel and a cover-up for post-swim comfort.
• Water shoes – The beach has a sandy bottom, but rocks and debris can be hidden just offshore. Water shoes protect your feet during entry and exit.
• Waterproof sunscreen (SPF 30+) – Apply 15–30 minutes before entering the water. Reapply every two hours, especially after swimming or towel-drying.
• Reusable water bottle – Stay hydrated. There are water fountains near the restrooms, but bringing your own reduces plastic waste.
• Small cooler with snacks – Light snacks like fruit, granola bars, or sandwiches help maintain energy. Coolers are allowed but must be kept in your vehicle or designated picnic areas.
• Waterproof phone case or dry bag – If you want to take photos, keep your phone protected.

Avoid bringing glass containers, alcohol, or pets to the beach area. These are prohibited for safety and cleanliness reasons.

Step 5: Check Water Quality Before Entering

Water quality at Alum Creek fluctuates due to rainfall, runoff, and algae growth. The ODNR regularly tests for E. coli and cyanobacteria (blue-green algae), which can cause illness or skin irritation.

Before swimming, check the current water quality report:

• Visit the ODNR Alum Creek State Park webpage for real-time advisories.
• Look for posted signs at the beach entrance—green means safe, yellow means caution, red means closed.
• Watch for visible signs of algae: greenish scum, paint-like streaks, or foul odors. If you see any, do not enter the water.

If the beach is yellow-flagged, limit time in the water and avoid swallowing it. If red-flagged, swimming is prohibited until further notice. Never swim during or immediately after heavy rain—runoff can carry pollutants into the lake.

Step 6: Follow Lifeguard Instructions

Lifeguards are on duty during operating hours, but they are not responsible for monitoring every swimmer at all times. Always obey their directions. If they blow a whistle or call out, stop swimming immediately and listen.

Key rules enforced by lifeguards:

• No diving—water is too shallow in most areas.
• No running on the beach or near the water’s edge.
• No glass containers or alcohol.
• Children under 12 must be accompanied by an adult within arm’s reach.
• Swim only between the buoys.
• Do not bring inflatables larger than a pool noodle—large rafts can obstruct lifeguard visibility.

If you’re unsure about a rule, ask a lifeguard. They’re there to help, not to enforce penalties.

Step 7: Swim Smart and Stay Aware

Even in a supervised area, personal awareness is critical. Never swim alone. Always have a buddy, even if you’re a strong swimmer. Be mindful of:

• Water depth – The beach slopes gradually, but sudden drop-offs can occur near the buoys.
• Currents – Wind-driven currents can push swimmers toward the dam or away from shore. If caught in one, swim parallel to the shore until you’re free, then head back.
• Underwater hazards – Logs, rocks, and debris may be hidden beneath the surface. Shuffle your feet when walking in shallow water to avoid stepping on them.
• Weather changes – Thunderstorms can roll in quickly. If you hear thunder or see dark clouds, exit the water immediately. Lightning strikes are a serious risk on open water.

Teach children to recognize the “reach, throw, don’t go” rescue principle: if someone is in trouble, reach for them with a pole or branch, throw them a float, but never jump in unless you’re trained.

Step 8: Exit and Clean Up

After swimming, rinse off with the outdoor showers located near the restrooms. This removes chlorine, algae, and lake sediment that can irritate skin or damage swimsuits.

Dispose of trash in designated bins. Even biodegradable items like fruit peels can attract wildlife and disrupt the ecosystem. Pack out everything you bring in.

Before leaving, check your belongings for lost items. Many visitors forget towels, hats, or phones. The park maintains a lost-and-found at the main office.

Step 9: Explore Other Park Activities

Swimming is just one part of Alum Creek’s offerings. After cooling off, consider:

• Walking the 2.5-mile Alum Creek Trail along the shoreline.
• Renting a kayak or paddleboard from the marina (seasonal).
• Having a picnic at one of the 20+ shaded shelters (reservations recommended).
• Visiting the Alum Creek Nature Center for educational exhibits on local wildlife and water conservation.
• Observing birds from the designated birdwatching platforms.

These activities extend your visit and deepen your appreciation for the park’s natural resources.

Step 10: Return for Future Visits

Alum Creek State Park is best enjoyed over multiple visits. Each season offers a different experience—spring blooms, summer sun, fall foliage, and even winter snowfall create unique atmospheres. Sign up for the park’s email newsletter to receive updates on events, water quality alerts, and seasonal closures.

Consider purchasing an annual Ohio State Parks Pass for $25. It covers parking at all state parks, including Alum Creek, and is cost-effective for frequent visitors.

Best Practices

Practice Environmental Stewardship

Alum Creek is a managed ecosystem. Every visitor has a role in preserving its health. Avoid using soap, shampoo, or lotions near the water. Never feed ducks, geese, or other wildlife—human food disrupts their natural diet and encourages dangerous behavior. Use designated trails to prevent soil erosion and protect native plants.

Respect Quiet Hours and Shared Spaces

While the beach is lively during the day, the surrounding areas are used by hikers, birdwatchers, and campers who value tranquility. Keep music low, avoid shouting, and be mindful of noise levels after 8:00 p.m. Even if you’re not camping, your behavior affects others enjoying the park.

Teach Children Water Safety Early

Children learn by example. Demonstrate safe habits: wearing sunscreen, staying within buoys, not pushing others, and asking permission before entering the water. Enroll them in a local swim lesson program—many Columbus-area YMCAs and community centers offer affordable lessons.

Plan for Emergencies

Know the location of the nearest first aid station (near the restrooms) and the park’s emergency number: 614-821-5520. Carry a basic first aid kit with bandages, antiseptic wipes, and hydrocortisone cream for bug bites or rashes. If someone is unresponsive or struggling, alert a lifeguard immediately—do not attempt a rescue unless you’re trained.

Use Sun Protection Consistently

UV radiation reflects off water, increasing exposure. Even on cloudy days, up to 80% of UV rays penetrate clouds. Apply sunscreen generously to ears, neck, feet, and the backs of knees. Reapply after every swim. Consider wearing a rash guard or UV-blocking shirt for extended exposure.

Hydrate and Take Breaks

Swimming is physically demanding. Even in cool water, your body expends energy. Take 10–15 minute breaks every hour in the shade. Drink water regularly—even if you don’t feel thirsty. Dehydration can lead to dizziness, cramps, or heat exhaustion.

Leave No Trace

Adopt the Leave No Trace principles:

• Plan ahead and prepare.
• Travel and camp on durable surfaces.
• Dispose of waste properly.
• Leave what you find.
• Minimize campfire impacts.
• Respect wildlife.
• Be considerate of others.

These aren’t just guidelines—they’re the foundation of sustainable recreation.

Real Examples

Example 1: The Family Outing

Maria and her two kids, ages 5 and 8, visited Alum Creek on a Saturday in June. They arrived at 8:30 a.m., secured a parking spot near the beach, and set up a shaded picnic blanket. Maria applied sunscreen and checked the water quality app—green flag. She kept her children within arm’s reach in the shallow zone and taught them to recognize the lifeguard whistle. After two hours of swimming, they rinsed off, ate lunch under a tree, and walked the nature trail. They left at 3:00 p.m., having avoided crowds and enjoyed a safe, educational day. Maria later shared photos and tips on a local parenting Facebook group, helping others plan similar trips.

Example 2: The Solo Swimmer

James, a 32-year-old fitness enthusiast, swims at Alum Creek three mornings a week during summer. He arrives before 6:00 a.m. when the beach is empty. He swims 1.5 miles along the shoreline using a buoy as a turn marker. He brings a waterproof watch, a hydration belt, and a whistle for emergencies. He checks the water quality daily and avoids swimming after rain. He never swims alone—his dog, a golden retriever, accompanies him on the shore. James credits the park’s consistent maintenance and clear signage for his ability to train safely.

Example 3: The First-Time Visitor

David and his wife, visiting from Indiana, planned a weekend getaway near Columbus. They read reviews online and assumed the beach was open year-round. They arrived on a rainy Tuesday in April and found the beach closed. Frustrated, they drove to the park office, where a ranger explained the seasonal schedule and recommended alternative swimming spots nearby. The ranger also gave them a free map and suggested the nature center. David returned in July, followed all the steps in this guide, and had the best swim of his life. He now recommends Alum Creek to every friend planning a Columbus trip.

Example 4: The Environmental Volunteer

Every Saturday in July, a group of 15 volunteers meets at Alum Creek to remove litter and monitor algae growth. Led by a local environmental science teacher, they collect data for ODNR and educate visitors about pollution prevention. Their efforts have contributed to a 40% reduction in beach closures over three years. They carry reusable gloves, trash bags, and clipboards. Their presence has inspired more visitors to pick up after themselves.
