The Moraine State Park Regatta (formerly called Regatta at Lake Arthur) is an annual regional event celebrated on Moraine State Park’s South Shore the first weekend in August. Our 2021 event weekend is scheduled for August 6-8. 2021 marks our 22nd event year, and we are excited to welcome you, your family, and your friends to come and see all that the Regatta has to offer.

Is the event really free?

Yes. Thanks to the generosity of our event partners and sponsors, the Moraine State Park Regatta is FREE to attend, including a host of live concerts, day-long instruction through SummersCool, kids crafts at the Lake Arthur Lily Pad, fireworks display and more. Most of our activities are available for FREE, and the park itself is a natural playground to explore and enjoy with a public beach, trails and much more. Pack a picnic and enjoy the day FREE!

Added fee-based activities are also available. Most of these are under $10 and completely optional. We are also featuring a Marketplace of Vendors, offering food, crafts and merchandise. We will have an ATM machine available at the event.


Parking is free. Please thank the parking attendants, as they work to ensure smooth parking for Park/Regatta guests. There are various parking areas that you will be directed to based on the time of your arrival.

What exactly is the Moraine State Park Regatta?

The Regatta is an annual summertime celebration of Moraine State Park. The event is FREE to the public and will be celebrating its 22nd year in 2021 and offers family-friendly activities on both the land and the lake. You can come and be a spectator of the event, but we really hope you’ll come out and play WITH us, get active and try something new. Generally, we want to expose new guests to the park, and further engage those who are already familiar with Moraine through a host of mini events through the weekend.

How many attendees are expected?

This is a showcase event for Butler County, and we have intentionally reached out to help build awareness for Moraine State Park as a regional resource. In 2019, the Regatta attracted 23,500 visitors to Moraine State Park’s South Shore.

We heard there was a car cruise...

In 2021, the car cruise will take place on both days of the event from 1:00 pm until 4:00 pm at the Point Picnic Area.

Is there a finale event?

For 2021, Saturday evening will close with a Fireworks Display following a performance by our headlining band. Sunday, we’ll finish off the event with the Native Butterfly Release & Tribute Finale. The mass release will take place from the main stage, and individuals can join us to honor someone special through the individual release of their Western Pennsylvania Monarch, enhancing the environment at the same time.

What should I bring with me?

Great question! Sunscreen and a great attitude — it’s playtime at the Regatta! You’ll want to remember to bring a bathing suit and towel if you plan to visit the beach or participate in a water instructional opportunity at SummersCool. Otherwise, you may wish to bring a yoga mat or beach towel if you’re joining one of our yoga events, or your own lifejacket for SummersCool events if you own one (although there will be plenty available on-site). Finally, pack a picnic if you wish, or visit one of our many food vendors!

What if it rains?

We’ve worked hard on this event all year and will press on rain or shine. There are various tents available for some shelter. Essentially, we understand that when we’re out in nature, nature is in charge. If any events are delayed, we hope to get right back on schedule when any rain clears.

In the event of severe weather, we will actively work to keep you updated on any cancellations or changes in the schedule. Make sure to check our social media pages, including Facebook and Instagram for last-minute updates, as well as this website.

What else do I need to know about the Regatta?

We want you to meet Moraine State Park if you haven’t yet and to make it a part of your summertime plans, this year and every year. Moraine is easily accessible from Route I-79 and just north of Cranberry Township. We’ve really tried to take the best of its history and enhance it with new relationships, new activities and new partnerships to showcase the best of a healthy place. The 2021 event is scheduled for August 7 and 8, beginning at 10:00 am each day on the South Shore at Moraine State Park.
