# Zion National Park

Region: SW UT, Ontario, Canada
Coordinates: 37.2982, -113.0263
Bortle class: 3 (1 = pristine, 9 = inner city)
Drive from Toronto: The main visitor center is just inside the South Entrance near Springdale, Utah, off Highway 9.
Best time: Spring and fall for cooler nights and lower crowds; new-moon weeks give the darkest skies.

## Overview
Zion's sandstone cliffs frame the sky like the walls of a cathedral, and the park's ongoing lighting retrofit has kept its canyon floor genuinely dark despite heavy daytime crowds. Step away from the shuttle stops after sunset and the Milky Way appears between the towering walls of Zion Canyon.

## What to see
Milky Way core between the canyon walls in summer, and clear winter constellations from the drier high country of Kolob Terrace.

## Highlights
- DarkSky International Dark Sky Park
- Kolob Canyons and Kolob Terrace Road, away from the main canyon, offer darker, quieter skies
- Park rangers run stargazing programs seasonally

## Tips
- The main canyon requires the shuttle in season — check whether it runs after dark before planning
- Springdale's lights spill into the lower canyon; head up-canyon or to Kolob for the darkest views
- Flash floods are a real hazard — check weather before heading into narrow canyons at night
