Yosemite National Park

Yosemite's high-country pullouts along Tioga Road are among the best beginner-friendly dark-sky spots in California. Glacier Point is the classic choice: a huge southern horizon over the valley, parking, and restrooms. Summer nights are mild but bring layers, elevations above 7,000 ft cool off fast. For smart telescopes, the open granite domes mean almost no tree obstruction, and the southern Milky Way core is fully available in June–August.

What this latitude gives you

From 37.8° north, anything above declination +52.2° is circumpolar here: it never sets, so it is available on every clear night of the year. Anything below declination -52.2° never clears the horizon at all.

Astronomical darkness lasts through every night of the year here, including midsummer, which makes this a rare site for a June or July imaging trip.

Bortle 3 is excellent rural sky and, for practical purposes, close to as good as Bortle 2 for most imaging. Galaxies are comfortable, faint nebulae are achievable, and unfiltered broadband work is genuinely productive.
