1. Antelope Valley California Poppy Reserve, CA
When to go: Mid-March to late-April
What you'll see: Poppies are beautiful when they cover the desert hillsides in orange flowers. But poppies are also fickle. If there’s too much rain, the Antelope Valley California Poppy Reserve can only expect a moderate poppy season. Too dry? Not a great bloom either. But that doesn’t mean you won’t see other wildflowers. Peak poppy season is late March to mid April—a short window if you want to catch the blooms at their height.
