While visiting Whistler, I brought my 9 year old here for some 1:1 time with him. Dropping in was easy. The waiver was not obnoxious. The staff were friendly and very helpful. We aren't expert climbers - though my son is a natural. He has autism. I mention this because the staff were very sensitive to his needs without making him feel "special". Within minutes he was in comfortable climbing shoes and a harness. For families coming to visit Whistler with children on the spectrum, the Core is an excellent activity for a rainy day. They have climbing walls for every level. I happened to be within ear shot of a private lesson and thought very highly of the instructor. For those looking to take lessons, the instructors appear very capable. We will definitely be back!
