I wanna say it's about 20 people per tour. Great tour by the way!!!
I think it is about 20. You need to make a reservation for your group.
There was about 14 people in a group going thru the underground city together. Everything else we did as group of about 40 including touring pendleton factory lunch at really nice steakhouse restaurant and wandering on own in town to chocolate store and other quaint shops.
