West End Yoga Studio’s popular Yoga on the Roof series returns to Tellus 360, offering outdoor Vinyasa classes from 10 to 11 a.m. every Saturday this summer. Now in its 11th year, the program invites participants of all experience levels to practice yoga atop one of downtown Lancaster’s most recognizable venues.

Students are encouraged to bring a yoga mat, towel, water and sunscreen for the 60-minute class. Participants should arrive between 9:45 and 9:55 a.m. and meet on the side of the building, where a community steward will provide directions to the rooftop location.

Advance registration is recommended. Weather conditions, including rain, extreme heat or poor air quality, may occasionally require cancellations, with registered participants notified by email or text.

Cost: $18 with advance registration; $20 walk-up. Location: 24 E. King St., Lancaster. For more information, call 717-406-9681 or visit WestEndYogaStudio.com.
