Sierra Club Wilderness Calendar 2025

The original nature calendar and a bestseller for over thirty years, the Sierra Club Wilderness Calendar once again sets the standard with its breathtaking images of North America's wild, natural beauty.
Great care and only top-quality materials go into the production of this exceptional Sierra Club wall calendar, now sealed with a removable sticker and no individual plastic wrapping. Our new environmentally conscious saddle stitch binding ensures easier recycling, and the photos and grids are printed on elemental chlorine free, Forest Stewardship Council®–certified paper containing a minimum of 60 percent pre and postconsumer waste. FSC® certification guarantees that the virgin component of the paper has been sourced from forests managed in an environmentally and socially responsible manner.
Each and every spread of this monthly wall calendar features a unique, vibrant photo of one of North America’s most spectacular wild places. For 2025, these include:
Sunrise from Reflection Lake, Mount Rainier National Park, Washington.
Rime ice on red spruce and hardwood forest, Monongahela National Forest, West Virginia.
Sunset over the La Sal mountains from Arches National Park, Utah.
Old-growth forest, Mount Baker-Snoqualmie National Forest, Washington.
