Waterton town site is entirely walkable, but that doesn’t necessarily mean you’ll want to do everything on foot. Bicycle, mo-ped and trolley rentals are available, and each offers an entirely different and enjoyable experience around town.
If you plan to explore the extremities of the park, a car is recommended. Waterton covers 505 square kilometers (195 square miles) of extraordinary territory, and every inch is worth a look. A rented vehicle (or yours, if you choose to drive it) will take you along back roads all over the park, leading to distant trailheads, rushing creeks, and mountain meadows that have to be seen to be believed.
