For folks traveling the Cascade Loop during Winter months: we advise that you request a vehicle with 4-wheel or all-wheel drive for your Cascade Loop trip. If possible, a vehicle with snow tires is recommended.

Make sure your vehicle is road trip ready! Start out with a fresh oil change, topped-off fluids, tires aired-up properly and in good condition, fresh wiper blades, and of course, a full tank of gas (unless of course you’re driving an electric car, in which case, plan where you will charge up .) Place GPS and/or road maps where they are easily accessible. Pack a first-aid kit, flashlight with fresh batteries, and if possible, an extra key. Pack for comfort and ease of travel. Do NOT forget charging cables (you know at least one will go missing or stop working right when you need it, so bring at least one spare.

Plan to put all permits and passes in a readily available location (not the dashboard where they will inevitably blow out the window when you can't resist driving with the windows down).
