Wadi Hali Dam in Al‑Qunfudhah Governorate, western Saudi Arabia, is one of the largest dams in the Kingdom in terms of size and storage capacity, and it sits on a valley whose length at the dam site exceeds 145 kilometers. This guide gathers static information related to the dam and the valley that is useful for anyone planning to visit the area: location, landmarks, activities, weather, and access.
Where is Wadi Hali Dam located and what is its climate like
The dam is situated on Wadi Hali in Al‑Qunfudhah Governorate, Mecca Region, western Saudi Arabia. The valley itself is one of the largest valleys in the Arabian Peninsula, characterized by high rainfall rates in its sources and tributaries, a feature that explains the volume of water storage the dam receives.
The surrounding area is characterized by shallow water‑bearing sedimentary formations, which makes the dam’s impact on the aquifer noticeable and relatively rapid. As for the weather, it remains tied to the rainy season in the sources and tributaries, which is the period that determines the valley’s condition and flow more than any other factor.
Wadi Hali Dam and Its Lake: The Main Landmark in the Area
The dam is the primary attraction. Its height reaches 95 meters, and its storage capacity is 250 million cubic meters, making it the second largest dam in the Kingdom. These figures alone explain why it is among the largest projects undertaken by the Saudi government to secure water and develop its sources.
The dam’s function is not limited to storage. It provides drinking water and supports the flourishing and development of agriculture in the area and its surroundings by recharging the aquifer, increasing the water stock, and compensating for what is withdrawn. At the same time, it averts flood hazards that threaten the city of Hali, towns, villages, and agricultural areas along the valley.
The dam’s lake is the façade seen by visitors: a wide water surface behind a massive concrete structure, surrounded by highlands and tributaries that flow into it. This very image has prompted specialized media coverage of the dam’s photos, reflecting its value as a visual landmark in the region.
The Valley and the Heritage Village: What to Do on Your Visit
The activities here are essentially natural. Viewing the dam and the lake and strolling around the valley are the direct activities, with the caution that the valley’s flow is subject to safety instructions issued by official authorities during discharge periods.
The heritage aspect is also present in the area. The Wadi Hali Festival, launched by the Hali Center Municipality of Al‑Qunfudhah Governorate, included sections such as a corner for productive families and artistic works, and the heritage village that featured craft tools, professional works, and popular heritage in poetry and folk games, as well as a children’s theater. These sections provide a picture of the type of cultural experience available to families in Hali Center.

Getting around the area requires a car, as landmarks are scattered over a wide area of the valley.
