If you’re looking to escape the light pollution of Mountain Home, you’re in luck. While enthusiasts often gather at Bruneau Dunes Observatory for its accessibility, scientific audits conducted by the National Park Service at Inferno Cone provide the most accurate reading of the regional sky quality, measuring at a Bortle 3.0. The transition between the urban infrastructure of Mountain Home and the more rural stretches of ID creates several ‘dark sky’ corridors.
The Best Times for Stargazing in Mountain Home
For the best results in Mountain Home, aim for a ‘New Moon’ window. In these dark-sky conditions, the absence of moonlight allows the Milky Way to cast visible shadows.
Expert Tips for Mountain Home Observers
Because Bruneau Dunes Observatory is a developed site, it often features established viewing pads and specialized equipment. For the best views at this spot, try to observe targets when they are highest in the sky to minimize atmospheric interference. 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.

Inferno Cone
Craters of the Moon NM
"Site on summit of Inferno Cone, 0.3 mile walk from parking area, OK for Public or telescopes. 5% clouds, increasing, only one data set obtained in early evening. High clouds to southwest accentuating light dome of Twin Falls. Southern horizon flat, north slightly blocked by mountains. Seeing very good, transparency good. Sky very dark at zenith, airglow seems less than usual, many light domes to east through south through southwest along I-15 corridor. No light dome extends more than 10 degrees above horizon.. Cars on highway 93 briefly point headlights directly at the site coming from the east."
Inferno Cone
Craters of the Moon NM
"Windy (10 mph ave), haze spread broadly to the south, probably from all the fires down there. Warm and dry, but not intensly so (RH 21%). No light domes detected visually yet, but can see Arco pretty clearly and the energy resource center down the road. Later in the evening, there are a wh0ole series of smallish light domes towards the ENE, not including Arco, whose lights are directly visible. Heading south, there is one dim dome thats going to be partially blocked by the lone tree thats up here on the SE side of the cone. Furthre south from that is a larger dome (Pocatello?) and maybe a fainter one to the right of the rightmost large dome. These will all be affected by the haze."
