Nova Scotia has one certified dark sky place in our directory: one dark sky preserve, Kejimkujik National Park and National Historic Site, certified in 2010.
The Royal Astronomical Society of Canada (opens in new tab) says a Dark-Sky Preserve keeps artificial lighting very limited and tightly controlled, with sky glow from beyond its borders no brighter than natural sky glow.
Check the moon phase before you book. A full moon makes faint objects much harder to see, as Great Basin National Park's stargazing page (opens in new tab) points out. Summer nights show the Milky Way at its densest, and winter brings Orion and the Pleiades (Great Basin National Park (opens in new tab)).
Every listing links to its own page with coordinates, certification details and visiting notes, so you can compare places and plan a route across several nights.
Meteor showers give more reasons to go: Great Basin National Park lists (opens in new tab) the Perseids in August, Orionids in October, Leonids in November and Geminids in December as good chances for shooting stars.
Before you go, see the Nova Scotia dark sky laws for how local lighting rules protect these skies.
Kejimkujik National Park and National Historic Site, at Maitland Bridge, is Nova Scotia's only dark-sky preserve, designated in 2010. Parks Canada lists a Dark Sky Viewing Area, and the park is open year-round. The visitor centre and camping run from the Victoria Day weekend to October 31, with serviced, unserviced and backcountry sites plus roofed accommodation, all booked through Parks Canada.
