Stargazing in Sitka is surprisingly rewarding if you know exactly where to set up your tripod. While enthusiasts often gather at local vantage points for its accessibility, scientific audits conducted by the National Park Service at Sitka Cross Trail provide the most accurate reading of the regional sky quality, measuring at a Bortle 5.0. The transition between the urban infrastructure of Sitka and the more rural stretches of AK creates several ‘dark sky’ corridors.
The Best Times for Stargazing in Sitka
Since Sitka sits in a transitional light zone, viewing is best during the New Moon or after midnight when some commercial lighting is reduced.
Expert Tips for Sitka Observers
Before heading out to local vantage points, we recommend arriving during civil twilight to scout the terrain safely. A medium-aperture telescope is ideal for resolving the rings of Saturn and bright star clusters here. Local enthusiasts often frequent this spot, making it a great place to meet experienced observers. Regardless of your gear, allow 30 minutes for your eyes to fully dark-adapt.

Sitka Cross Trail
Sitka NHP
"Set up camera system in the frozen muskeg along the Sitka Cross Trail. A nice open locatiaon with no direct glare and a good panorama of the Sitka light dome. Sky glow from Sitka was fairly bright and, along with the heavy moist air, night sky observations were moderately impacted. The Milky Way was barely visible to the naked eye and the light dome from Sitka appeared to rise to at least 30 degrees above the horizon with a width of 90 degrees or so. Even with this local brightening of the sky this is a fairly nice location to experience the nighttime environment free from the direct glare and light trespass found throughout the community. Heavy frost was present almost immediately after astronomical twilight."

"Set up 100' off road from the Park entrance sign in a clearing of small trees in the muskeg. Perfectly clear night but aurora was readily visble at end of astronomical twilight to the north and northeast. No visible light domes from either Gustavus or the more distant Juneau. The Milky Way was easily visble overhead but faded into the brightening aurora to the north. Daytime visibility was 100 miles + while flying in to Gustavus earlier in the afternoon. Was able to see 12 stars in the Pleadies naked eye. Stars visible to the horizon in all areas except where the aurora was present. Frost was quick to coat all of the equipment. SQM reading of 21.63."
