NPS/Hoerner. Arrives in late October, with warm but pleasant temperatures and generally clear skies. The camping season begins in fall and so do the Ranger Programs, which continue through spring. Although it is relatively uncrowded at this time of year, the weeks leading up to Death Valley '49ers Encampment (second week in November) and the Thanksgiving holiday are busy. It is the most popular time to visit Death Valley. Besides warm and sunny days, the possibility of spring wildflowers is a big attraction. If the previous winter brought rain, the desert can put on an impressive floral display, usually peaking in late March to early April. Check our website for wildflower updates. The Death Valley Dark Sky Festival weekend is also very busy. The spring break season brings crowds to Death Valley between mid-March to late April. Campgrounds and lodging are usually packed at that time, and reservations for this season are typically made months in advance.
