Squirrel Creek Lodge, an 18,000-square-foot former steakhouse in Littleton, looks a lot like any other event space used for corporate get-togethers or run-of-the-mill wedding parties.
But Squirrel Creek has hidden depths. Nearly every weekend, droves of people visit for racy parties where open-minded couples meet other open-minded couples looking to spice up their sex lives.
Many participants call it "the lifestyle," although it's also commonly known as swinging.
Owner Kendall Seifert said Squirrel Creek is the biggest venue of its kind in the nation.
Among other things, Squirrel Creek hosts Scarlet Ranch, a 50,000-member swingers club that Seifert started more than a decade ago, before selling it. Members and guests come to the facility not necessarily to have sex, but to "go out to a club without kids," he said. "No thumping music, no bar fights."
