"Whether you haveone day or three weeks and whether you’re interested in wolf-watching, geology, photography, wildflowers, or animal tracking, consider reaching out to the Yellowstone Forever Institute (YFI). Formed in 2016 when the Yellowstone Institute merged with the Yellowstone Park Foundation, the nonprofit YFI does single- or multi-day personalized programs year-round. And then there’s the institute’s catalog of hundreds of scheduled educational and experiential programs in both summer and winter. Seminars like the three-day “The Bears of Yellowstone” include classroom presentations, field excursions, and lodging at the Lamar Buffalo Ranch Field Campus. The two-day “Ghost Hotels” is based at Old Faithful and focused on stories about the park’s oddities and ghosts. Novice and experienced ornithologists flock to attend YFI’s “The Birds of Yellowstone.”"
