Harrat Lunayyir, Volcanic field in northwestern Saudi Arabia
Harrat Lunayyir is a volcanic field in northwestern Saudi Arabia composed of dark basalt lava flows scattered across the desert with patches of low vegetation. The terrain features rough volcanic rock formations and visible surface fissures that reveal the underlying geological structure.
The field formed millions of years ago from repeated volcanic eruptions and remains geologically active today. In 2009, earthquakes and ground movements prompted the displacement of residents and drew significant scientific attention to the site.
Local communities have long used the terrain for herding and agriculture, taking advantage of volcanic soil conditions in certain areas. The dark lava landscape shapes how people move through and relate to this part of the desert.
The site is accessible for walking across the lava terrain, and visitors should wear sturdy footwear and bring water due to the rough surface. The exposed desert location can be very hot with little shade, so early morning or late afternoon visits work best.
The field contains underground cave systems where researchers discovered evidence that animals lived in these spaces for thousands of years. These hidden caves offer insight into how long wildlife has inhabited the region.
