ABOUT THE CLUB

This rustic, low-key club in the North Boulder Arts District is located in Emerald City. PORTAL° brings you two wood burning neighborhood saunas and two ice cold plunges to chill, sweat, and connect. PORTAL° now hosts a consistent series of events. Scheduled offerings include yoga, DJ's, mixers, and meditations for our members and credit pack users conducted at the Orbit Clubhouse, an indoor recreation facility in collaboration with Little Horse Vintage. For those only joining us for temperature sessions, we have towels available and recommend wearing or bringing either a swimsuit or clothing that can get wet. Guests generally alternate between heat exposure (sauna) and cold exposure (cold plunge) three times per session, spending 15 minutes in the heat and 3 minutes in the cold. We ask that you are respectful of their booking window to allow others to enjoy the activation. Water is recommended and complementary throughout your session and well-being enhancements and merchandise are available for purchase.

BENEFITS OF CONTRAST THERAPY

The alternating exposure to hot and cold in a social space known as thermaculture has physical, psychological & social benefits. Our facilities change the way you relate to recreation.

Mike Price, a poet and longtime bookseller, opened the original Little Horse Vintage shop, in downtown Boulder, Colorado back in 2001. He's back in collaboration with PORTAL° to bring you an amazingly curated selection of vintage hifi audio equipment, vinyl records, rare and collectable books, art, unique housewares, gifts and mid-century modern furniture.
