An indoor park featuring 15,000 square feet of trampolines is set to open in West Duluth this summer.

Planet 3 Extreme Air Park announced Friday that it will be the first indoor trampoline park in Duluth when it opens in July in the former Grainger Industrial Supply building at 101 N. 46th Ave. W.

The company opening the Duluth trampoline park has been around for five years, operations manager Mo Haretuku said. The first Planet 3 locations are opening in Duluth and Clarksville, Tenn., but the company has eight other trampoline parks in the United States under other names, Haretuku said by phone from the company’s park in Savannah, Ga.

"We're excited. We're going for a more millennial-friendly brand. It's a cooler atmosphere that we're going for that will appeal more to 15 to 25-, 30-year-olds because they're the ones that most frequent our parks," he said.

The West Duluth trampoline park will feature interconnected floor-level padded trampolines, a large open jump area, a trampoline dodgeball stadium, basketball dunk centers, pits filled with foam cubes for jumping, a slack line and a multi-lane ninja warrior course, according to Planet 3's announcement.

The park's trampolines are designed to provide "active entertainment for all ages, shapes and sizes," and the park will offer activities that include open jump time, trampoline dodgeball competitions, dunk ball, ninja courses and fitness classes, the company said. Every Friday and Saturday night, the park plans to transform into a club-like setting with black and laser lights for jumpers of all ages.

The park will be able to host birthday parties, corporate team building events and field trips. Haretuku said Planet 3's trampoline parks are also popular fundraising locations.

The concept is growing because it appeals to a range of ages and abilities, he said.

"There's not many venues that you can go to where you can bring anyone from a toddler up to 50-year-olds and everybody can participate in the fun. Normally when you go somewhere, someone is always left out. ... Almost everyone can walk, skip or jump on a trampoline. It's a great way to provide family fun, work parties, birthday parties," he said.

When opening a new trampoline park, Planet 3 looks at location and a city's history and tourism industry, Haretuku said. The company searches for space near residential areas that is large enough, with tall enough ceilings to accommodate a trampoline park - and not all cities have that available, he said. They try to open in cities that don't yet have anything like a trampoline park.

"You get a better workout coming our trampoline than a lot of people get at the gym - and when they realize that, they love bringing their kids, they love coming themselves to be able to do that and just to have fun. It's another great venue for the Duluth community to be able to visit and have another alternative to going to a movie on the weekend," he said.

Planet 3 is planning to hire 30 to 40 employees for the Duluth location; it will be posting updates for hiring and its opening date on social media, Haretuku said. Find more information by searching for "Planet 3 Extreme Air Park Duluth" on Facebook.
