Stargazers heading to Big Bear this fall can trade a blanket on the ground for a guided walk toward the dark, as the mountain town gears up for three telescope-equipped night hikes along a trail near Snow Summit. The hikes are part of One Sky Week, a stretch of astronomy programming built around Big Bear's clear, high-elevation skies.
According to the official event listing from bigbear.com, One Sky Week runs November 1 through 7, 2026, and includes three night hikes with telescope stargazing. The hikes are led by Big Bear Hiking Adventures along Towne Trail, a route the listing describes as mostly flat and roughly 1.2 miles long. Each hike starts from Snow Summit at 880 Summit Blvd., with an 8 p.m. start time and a request that attendees arrive by 7:45 p.m.; once the hike wraps up, everyone is shuttled back to the starting point, per the same listing.
Not every outlet has the dates lining up the same way. Big Bear Cool Cabins and Destination Big Bear both describe One Sky Week as running November 2 through 8, 2026, a range that begins one calendar day after and overlaps the official November 1–7 dates for six days. Big Bear Cool Cabins tells visitors to “plan your visit around One Sky Week, November 2–8, 2026, which will feature astronomy-related activities and night hikes,” while Destination Big Bear similarly invites readers to “Join One Sky Week in Big Bear Lake from November 2–8, 2026.” As reported by NBC Los Angeles, the individual hikes themselves are set for November 6 and 7, timed to coincide with the broader dark-sky conference, and the week also includes a Locals' Night on November 4.
Why the Week Is Built Around a Global Dark-Sky Conference
One Sky Week falls in the days leading up to Dark Sky International's annual Under One Sky conference, according to bigbear.com. NBC Los Angeles describes that gathering as a 24-hour virtual conference, and bigbear.com notes this year's theme is Night in Balance, with sessions exploring growing light pollution, satellite proliferation, and other emerging challenges facing night skies. Big Bear's own Dark Sky Initiative also takes part in Dark Sky International's separate sustainability push, Dark Sky Week, which the organization calls a global celebration of the night highlighting dark skies' importance to wildlife, communities, science, and cultural traditions.
The appeal of hosting any of this in Big Bear comes down to geography. Destination Big Bear notes that the town's high elevation and minimal light pollution make it one of the better spots around to see thousands of stars, constellations, and even meteor showers with the naked eye. There's also a conflicting description of the hiking terrain itself: while bigbear.com calls Towne Trail mostly flat, Destination Big Bear refers to a route it identifies as Ranger Road 2N08/Towne Trail as steep, leading to a clearing with expansive night-sky views.
Planning a Visit, Packing Layers and Other Nearby Options
Visitors booking lodging around the event can find a financial incentive built in. Bigbear.com is offering 10% off direct bookings for stays from November 1 through 9, 2026, using the promo code ONESKY10, subject to availability. Ticket prices and exact times for One Sky Week programming are available on the event website, per NBC Los Angeles.
Fall nights at elevation can turn cold fast, and both the hiking organizers and local tourism sources are blunt about it. Big Bear Cool Cabins advises visitors not to forget to pack layers, while NBC Los Angeles notes that Big Bear's higher elevation calls for warm layers and a solid coat. For those looking to extend the stargazing beyond One Sky Week, Destination Big Bear lists the Leonid meteor shower's peak viewing night as November 17, and points to free sidewalk astronomy offered by Barrel 33 in The Village at 40754 Village Drive, weather permitting, along with free, reservation-required tours of the Big Bear Solar Observatory that accept donations. Travelers who stick around town a little longer will also find Big Bear Oktoberfest wrapping up on November 14, per NBC Los Angeles, giving fall visitors more than one reason to linger in the mountains.
