You are welcome to use the pool, spa and sauna! You will need the same key card you used to open the Bretz Mill gate. The key card works on the gates on either side of the top deck. There is also a key needed to use the bathrooms and the sauna. Both the key card and the key will be provided by Shaver Lake Vacation Rentals. The hours are 10am to 10pm. The minimum age for the spa is 14. Please follow the rest of the rules posted at the facility.
