At Sertich Ice Center, skaters of all ages glide across the frozen plane of an expansive, NHL-size rink during 90-minute public ice-skating sessions held year-round. After strapping on pairs of rented skates and stepping onto the icescape’s frosty floor, couples cruise hand-in-hand and foursomes etch cubist portraits of their favorite hockey players into the ice. The sprawling indoor rink allows aces plenty of room to wind up for triple axels without colliding into more leisurely skaters. Weary legs find respite while virtual zambonis race across screens in the arcade room, and nearby vending machines dispense the fuel necessary to get back on the ice.

Sertich Ice Center’s rates fluctuate throughout the week.
