While Whites City itself is a very small place, the best time to visit is largely dictated by the ideal conditions for exploring nearby Carlsbad Caverns National Park.The spring (March to May) and autumn (September to November) months are generally considered the most pleasant. During these periods, the weather is typically mild, making outdoor activities and the walk down into the Caverns comfortable. You'll find fewer crowds compared to the peak summer season, which allows for a more relaxed experience both in the Caverns and around the park.Families often find late spring or early autumn particularly good. The temperatures are suitable for exploring the park's outdoor trails without being too hot, and it's a great time to see the bat flight programme in the evenings, which is a highlight for many children.For those who prefer to avoid any potential heat, winter (December to February) can also be a good option, with cooler temperatures, though some outdoor visitor centre facilities might have reduced hours.
