If you are planning on skiing more than two days in or outside Colorado, your cheapest option for lift tickets is to purchase them in advance! You may find that buying a “pass” is going to be your best option. Liftopia is an awesome site to find great deals on lift tickets and rental equipment.
Epic Pass – Vail Resorts owns basically all the resorts on I-70. So, if you plan on skiing 2x a year or more than four days, you should definitely consider buying a pass. Important to note that you can’t get discounted passes on Liftopia for Epic Resorts aka Vail-owned resorts.
Rocky Mountain Super Pass – With this super pass, you get Winter Park/Mary Jane + Copper + Days at Crested Butte, and Steamboat. It is a total steal if you want to ski in a few areas.
