In only its second year, Splash House is shaping up to be a top — and for now, one of the few — summer events to attract a healthy smattering of overnight tourists to Palm Springs.

The city, and indeed the Coachella Valley itself, have gained traction in recent summers as a weekend destination for Southern Californians looking for a relatively inexpensive getaway. Hotels have caught on, enlisting DJs to spin at afternoon pool parties, while local tourism officials have crafted summer ad campaigns to saturate markets from San Diego to Burbank. The ads mostly tout the region’s laid-back summer lifestyle, without any actual event hook. Splash House, a weekend-long roving pool party with three outdoor music stages around three area pools, has come along to fill that void.

This year Splash House will feature both live performances and DJ sets at The Saguaro Palm Springs, Hacienda Cantina and Beach Club and the Hard Rock Hotel Palm Springs. The event — launched last year by Tyler McLean and his sister Kelly McLean, both Palm Springs natives — is now partnering with music production giant Goldenvoice, which adds an enormous layer of marketing and legitimacy to the event.

“With one year under our belt, we were able to sell out our pre-sale before even announcing a lineup,” said Tyler McLean. “This was a big benchmark for Splash House to achieve in its second year.”

Last year, Splash House was a two-day event with DJ sets spread across three neighboring south Palm Springs hotels. This year, Splash House is set for June 13 to 15, with both DJ sets and live performances, along with other peripheral attractions like evening parties.

“For new features, we are expanding into the night by adding after parties and hosting several small activations like a community brunch, yoga by the pool, and other activities,” McLean wrote in an email.

The weekend also will offer a first look into the Hacienda Cantina Beach Club, a renovated restaurant on South Palm Canyon Drive that also will include a pool, bocce ball courts, an outdoor bar and cabanas. The project is another foray into the Palm Springs music scene by Goldenvoice and its dance music component LED. Expect a number of ticketed Goldenvoice events at the Hacienda, said Nicole Novak, food, beverage and entertainment manager at the Hacienda Cantina Beach Club.

“The whole point of the place is to have something that’s open to the public that’s not charging a huge swim-club fee,” said Novak in an interview last week. At the time, the Hacienda was “85 percent” complete, and would “most definitely” be ready for the Splash House crowd next weekend. After Splash House, the Hacienda will be open for regular business.

“We want to really adhere to the locals — people who want to come in and eat,” she added. “The point of this is for people to come one, come all, and enjoy the facilities, and eat and drink, obviously.”

Diners can expect a Baja-inspired menu with lots of fresh fish, sustainable and organic foods. A number of juicers on the property will be squeezing out any number of fresh juices.

“Lots of agave juice. No simple syrup. We’re really going for fresh, locally sourced,” said Novak.

There will be guacamole made to order and a raw bar, featuring ceviche.

“We’re really going all out on the food and beverage part,” she added.

The opening of Hacienda will be just as closely watched by tourism observers as Splash House. The two are viewed as emblematic of Palm Springs’ tourism strategy, trying to catch the attention of the sort of young travelers who have discovered the desert during the Coachella Valley Music and Arts Festival.

“Coachella showed there is a market for the younger set to come and enjoy the Palm Springs area, and the city has capitalized on making the Palm Springs very ‘millennium-friendly,’ ” remarked Mary Jo Ginther, director of tourism for the Palm Springs Bureau of Tourism, as she listed hotels like the Ace Hotel and Swim Club, Saguaro and Hard Rock as three of the most obvious properties that have made attracting millennials a marketing centerpiece.

And Palm Springs is particularly well-suited for the drive market, Ginther added. “It’s a three-day weekend event,” she said of Spalsh House. “But I have to think that as it grows, we’ll get visitors flying into L.A. from the west and further, and driving out for the three days.”

From the beginning, McLean said, creating an event to attract summer visitors to the desert has always been what he wanted Splash House to achieve.

“Pitching summer in Palm Springs has been the goal from the start. The potential is there for summer tourism, especially with the younger demographics, but there has to be a reason to come,’ said McLean. “We built Splash House to be that reason and we’re hoping to continue to grow it into a bigger draw.”
