Spring is springing. And we all know what that means. It means that the 2025 morel mushroom season is underway. To increase your chances of success, we put together a map of recent morel sightings and nearby camping options. The map updates weekly throughout the springtime morel season using data from The Great Morel. So grab a mesh bag, book your campsite, and head into the woods. Have fun and remember to practice Leave No Trace principles.\n

Trending morel spots

Last Updated: June 7, 2025

Using the data from The Great Morel, we can get a sense of where morels are most abundant. We'll break this down into 3 areas:\n

Started poppin': The first morel sighting was reported in the last week.
Still poppin': Morel sightings have been reported prior to last week and continue to have reported sightings.
Stopped poppin': Morel sightings have been reported, but not in the past week.

If you don't care about recent morel sightings and you just to see all of the 2025 season, then check out the map below.
