Tennessee has two certified dark sky places in our directory: two dark sky parks.
The names to know: Obed Wild and Scenic River (certified 2017) and Pickett CCC Memorial State Park & Pogue Creek Canyon State Natural Area (certified 2015).
The DarkSky International place types guide (opens in new tab) describes a dark sky park as land with notably dark, star-filled skies that is protected for its scientific, natural, educational, cultural or recreational value.
For the darkest nights, plan around the calendar: the National Park Service says the darkest skies come during a new moon or when the moon is below the horizon (opens in new tab). On clear, moonless summer nights the Milky Way looks densest, while winter brings Orion and the Pleiades, according to 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.
Before you go, see the Tennessee dark sky laws for how local lighting rules protect these skies.
