When it's this cold outside, all I want to do is sit in my apartment piled under blankets. To avoid that fate, it's sometimes necessary to get the heck out of town. Luckily, this Saturday, Sunday and Monday present the perfect excuse to do just that, because all national parks in California are free.
Take a road trip to the snowy, postcard-perfect landscape of Yosemite, experience the I-feel-like-I'm-on-Mars vibe down south in Joshua Tree National Park, or venture to the North Bay for a gander at the salmon-spawning streams in Muir Woods National Monument. They'll waive entrance fees, commercial tour fees, and transportation entrance fees so you can save some dough on a well-deserved adventure far away from the grind.
