Keep Sierra Clean Day 2025
October 12, 2025
10:00 AM - 2:30 PM
SAVE THE DATE for the 17th annual Keep Sierra Clean Day!
Mark your calendars + plan to join us on Sunday, October 12th, from 10:00am-2:30pm , for our annual mountain clean up event, a day of fun, high fives, good vibes and smiling faces.
With chairlift access up Grandview, enjoy the autumn ride up to the top of the mountain + snap a photo of the lake view. Hike the 2.5 miles back down to the base while collecting trash + treasures lost, and scoping out your winter lines before the snow blankets Sierra. Please note, if you ride the lift up, the only way back to the base area is to hike down; no scenic rides available. Please adhere to your own hiking ability.
Before or after your hike, get the chance to continue to plant new roots at Sierra in partnership with the Sugar Pine Foundation + USFS. This year we will be working on reforesting the area behind 'A' lot. Visit the tree planting station in the back of 'A' lot for demonstrations and supplies to plant your own seedling at 10:30am OR 12:15pm!
Free lunch in Solstice Eatery for participants from 11:30am-1:30pm.
