Parties Looking for a great place to have a birthday party? At the Sanctuary Rock Gym we have had hundreds of birthday parties for kids ages 4 and up. Climbing is a great way to celebrate your birthday with friends and family, and a great way to work off that cake too! We will reserve our upstairs Party Deck to use as your party's basecamp. The deck is a great vantage point to view the action and set up the cake, pizza and presents. From decorating the Party Deck, calling in your pizza order or arranging the caterer, we can help facilitate all your party needs. Check out our parties section for details.
