🌌 From the Research Notes — Banff sits within one of the largest certified International Dark Sky Preserves in the world, covering 6,600 square kilometres of Banff and Jasper National Parks. The designation means light pollution is actively managed across the entire park boundary. On a clear night away from the Banff townsite, the Milky Way is visible to the naked eye for roughly 250 nights per year. The stargazing tours in the Tours section all exploit this — their meeting times shift nightly to match astronomical twilight, the window after sunset when the sky darkens but the horizon still holds enough glow for foreground photography. What most visitors miss is that the town's own lighting policy contributes to the preserve: all commercial and street lighting in Banff is downward-directed and amber-tinted to reduce scatter. Standing at the edge of Vermilion Lakes around 11pm, with the beaver-dammed wetlands quiet and Mount Rundle silhouetted against the Milky Way's core, is the version of Banff that takes an hour of patience to access but belongs on a different level from the standard viewpoints.

📜 There is also a lesser-told founding story at Cave and Basin. The hot springs were claimed by three CPR railway workers in November 1883, who fenced off the cave and attempted to develop it as a private bathing resort. The Canadian government refused to recognize their claim, expropriated the site two years later, and set aside 26 square kilometres as the "Banff Hot Springs Reserve" in 1885 — the act of Parliament that would expand in 1887 into Canada's first national park. Cave and Basin is, in the most literal sense, the place where Canada decided that natural heritage should belong to everyone. The endangered Banff Springs snail, endemic only to the outflow stream of these specific hot springs, has survived in that water for thousands of years and still lives there today.
