April in Badlands National Park is a good month: highs around 62°F, lows around 36°F. Crowds: moderate — #6 busiest of the park's 12 months. Rain arrives — the clay turns slick, and Saddle Pass is a bad idea wet. The editorial best window here is May & September–October. You get about 13h 26m of daylight. To finish Cliff Shelf Nature Trail (15m) before dark, leave the trailhead by about 7:17 PM.
