From a review of the new climbing gym in Atlanta called Stone Summit which is the “largest in the U.S.”
“The building itself is massive, and the parking lot is even larger. To put it into perspective, this is the only climbing gym I have been to with an approach.
Stone Summit features a route that requires a 70 meter rope. Not only does the main wall top 60 feet at its highest point, but there is a second story above the lobby featuring multiple 30 foot walls.”
