Protected areas
Research 4 protected areas within weekend reach of Ontario, classified from Wikidata types and ordered by measured straight-line distance from the city centre. Distances only — no travel times, schedules, or rankings.
Each place is classified from its own Wikidata type, not from its name, and is ordered by measured straight-line distance from the centre of Ontario. Distances are great-circle kilometres between two published coordinates — this page does not publish travel times, transport schedules, opening hours, ticket prices, or rankings. Confirm access, facilities, and seasonal conditions with an official source before travelling.
Reachability is a second axis over the same places: the category says what a destination is, the band says how far it sits from Ontario. Distances are measured in a straight line — this page publishes no travel times.
Ordered by straight-line distance from Ontario, closest first. Distance bands: nearby is up to 60 km, day-trip distance is up to 120 km.
