To avoid long lines at the entrance gate and parking congestion, plan to arrive early in the morning or late in the afternoon. Late afternoon and evening visits can be the most enjoyable. The lighting is better for photography and viewing the park features, temperatures are cooler, and the parking areas and trails are less crowded. More than 1.5 million visitors come to Arches National Park each year, and that number is growing. Between March and October, you can expect limited parking at all destinations. Parking at popular trailheads are usually full most of the day.
