Never heard of Devil’s Postpile? Well, it’s on the eastern side of the Sierra, near Mammoth Lakes, and it’s another one of those underdiscovered gems in the California parks. It’s only open during the summer months (this year’s opening is June 7), so, plan a trip this summer and discover a park that’s not as crowded as many you’re used to.

You can fish, ride horses, camp (first come, first served), hike, photograph the stunning scenery, or just enjoy your surroundings. There is no lodging or meal service inside the park, so bring your own snacks and water for a day trip, or plan to spend the night in nearby Mammoth Lakes.

If you plan to camp or visit Red Meadows Valley, you have to pay a mandatory transportation fee, and use the mandatory shuttle bus, unless you are disabled. With proof of disibility, you can take your own car into the Red Meadows area.

Remember, summer nights can still be cool in the Sierra, so bring a sweater or jacket, and enjoy your stay!
