Here's a DogTrekker secret: Stories about California SNO-Parks are among our most-read each year! There's lots to bark about when it comes to these dog-friendly, snow-covered playgrounds scattered on U.S. Forest Service lands throughout the Sierra Nevada mountains. Pick your destination. Reserve your permit ($15 per day or $40 per season for 2022-2023). Arrive early for easy parking and get ready to romp with your furry friend.
