Where to See Black Bears in Yosemite National Park in the Fall

Most of Yosemite's bears aren't black. The park says most are brown, blond, or reddish brown, and the one on this page looks like a cinnamon-colored teddy bear that has never heard of a diet. Yosemite is home to an estimated 300 to 500 of them (NPS), and late October is one of the best times of year to find one.

I cover the bear, plus 13 other animals, in my Yosemite National Park guide. Here's the part that changes your plans in the fall.

Bears live in forests and meadows across the park, and the park's current conditions page (updated October 30, 2026) says they "remain active in all areas" (NPS). Nothing is guaranteed. Bears avoid people, and you can have a lovely visit without seeing one.

How to Recognize a Yosemite Black Bear

If it's a bear in Yosemite, it's an American black bear (Ursus americanus). Grizzlies are gone from California; the park says the last known one was shot outside the Yosemite region in the early 1920s (NPS).

So don't count on color. Adult males average about 250 pounds and females about 150, and the park says the biggest one it ever captured weighed 690 (NPS).

Where and When to Look in Fall

October is bear feeding season. Bears in hyperphagia, the stretch before winter sleep, can eat up to 20,000 calories a day, which the park's bear team translates as roughly eleven pounds of acorns (NPS). Yosemite Valley's black oaks have been a magnet in past acorn years, and the same park blog describes "bear jams" on roads and trails when the crowds showed up.

Here's the catch for a late-October trip: as of October 30, the Tioga Road and Glacier Point Road are both closed for snow (NPS). That takes Tuolumne Meadows and the high country off the table for now. Plan your bear watching around the Valley floor and the parts of the park the roads still reach, and check the conditions page before you leave, because snow can change that fast.

How I'd spend the time: pick a meadow edge in the Valley, get there in the first hour of daylight or the last, and bring binoculars. Don't chase a sighting. Deer are common in the Valley's meadows, so you may get only deer, and a bear you stumble on is a better memory than one you hunted down.

What Bears Are Doing in Fall

Eating, mostly. Acorns are a favorite fall food, alongside the grasses, berries, ants, and insect larvae that make up the rest of the diet (NPS). The park says bears weigh the most in fall.

When the cold sets in, they den in hollow trees or logs, under tangles of roots, or in caves among big rocks. Their sleep isn't deep and they leave the den from time to time. Females give birth during winter to one to three cubs, which stay with their mother for about 16 to 17 months (NPS). If you're coming later in the season, my Yosemite winter guide covers what else changes once the snow arrives.

Watching Bears Without Hurting Them (or Yourself)

The distance rule is simple: outside developed areas, stay at least 50 yards away, which the park equates to four shuttle buses (NPS). If a bear approaches you on a trail, or turns up in a campground or parking lot, the park wants you to yell loudly and aggressively to scare it off. Bears may bluff charge, especially around food or cubs. Attacks are rare, and the park says no one has been killed or seriously injured by a black bear in Yosemite.

Food is the reason that record holds. Anything with a scent counts: canned goods, drinks, toiletries, trash, even an empty ice chest. In daylight you can leave food in a car with the windows closed and everything out of sight; after dark it goes in a food locker. Campers use lockers, overnight backpackers must carry bear canisters, and the park says violations can bring a fine of up to $5,000 (NPS). Obey the speed limit too, since bears have been hit by cars.

Never call, bait, feed, or follow a bear, and skip the flash. If a photo needs you to get closer, you don't need the photo.

The Short Version

Look in the Valley at dawn and dusk, keep 50 yards, lock up everything with a scent, and treat any bear you see as a gift. My Yosemite National Park guide profiles 14 animals with photos, plus one-, two-, and three-day plans. For the park's own pages, start with Yosemite's bear page.
