Great Lakes dark-sky destinations
Map pins represent park areas, not official entrances, parking areas, safe viewing sites or travel routes. Green = International Dark Sky Places; blue = other designated preserves; purple = certified community; gold = selected site or approximate device position.
CARTO Voyager uses the public Vercel basemap key, with an OpenStreetMap fallback. Always check the actual park operator for safe and lawful entry.
Which sky looks better tonight?
On demand, compare up to four filtered U.S. or Ontario park references by their best available dark hour in the next 18 hours. U.S. NWS grids and Canadian MET Norway models are different products, not an exact cross-border ranking. Access and local light pollution are not verified.
Select a state or use your location before comparison.
Four decisions before the drive
1. Is a major meteor shower active, or is this general stargazing?
2. Are clouds and moonlight favorable in the hours after dark?
3. Are the park entrance, trails, parking and nighttime access legal?
4. Is an alternative area more promising without additional hazards?

Method and limits
U.S. locations use the existing NWS cloud and astronomical meteor-viewing engine. Observing scores are relative conditions, not probabilities or meteor counts. Ontario destinations use MET Norway Locationforecast 2.0 global-model cloud cover under its CC BY 4.0 license, plus the existing astronomical index; NWS data remain specific to U.S. destinations. Check Environment Canada and park operators for local warnings and access. No live gate, campsite, ice or winter road status is inferred from a map.
Michigan DNR documents six state-designated preserves with differing winter plowing. National and county parks may have separate nighttime-event rules. Check the official destination immediately before visiting.
