The extreme heat in Death Valley poses significant risks to visitors, particularly those unprepared for the harsh conditions. The park has seen multiple heat-related fatalities in recent years, often involving older individuals. Temperatures exceeding 120°F (48.9°C) are not uncommon, and the combination of heat, desolation, and long distances can quickly become life-threatening. Visitors are urged to exercise caution, especially during peak summer months, and to avoid venturing into remote areas without adequate preparation.
