Rodney Chai, a meteorologist from Monterey, led a group of hikers to Lundy Canyon and McGee Creek as recommended here, last week, and they “found gold (and then some)!”
Reporting that they were collectively “speechless by the vibrant display of yellow and apricot.”
Should you hike Lundy Canyon, you’ll find the first mile to have a lot of green (20-30%), though Chai estimates it will “be excellent viewing for the upcoming weekend.”
His group found the most intense color at about “mile 2, where a forest of quaking aspens reside.” Above that, the trail was past peak with a lot of leaves that had fallen.
McGee Creek, he continued, “was simply splendid from start to finish with a golden sea of aspen and apricot. The range of yellow and apricot, as well as the ability to see up the canyon made this his favorite hike.
