In our trip to Lassen last month, we ran into bears in two different places in the park. A mama and cub slowed us down for a minute on the trail to Devil's Kitchen, while we watched them from afar, and waited for them to clear the trail. That's a photo below as mama headed up the trail, and the little cub scampered after her.
And near the Crags Group campsites, we saw one running down the road...to our delight.
In the last ten years and 1500+ miles of hiking in the Sierra, we've only seen bears a handful of times: at Rancheria Falls and Virginia Canyon in Yosemite, and in the remote Carson River area of the Carson-Iceberg Wilderness. The two this year were the best sightings ever.
