Tarbela Dam, on the Indus near Ghazi in Haripur district, is one of the largest earth and rock-filled dams in the world, and most visitors see it from public parks and viewpoints around the lake rather than from the dam structure itself. The dam and its powerhouse are a secured WAPDA installation, so a close-up visit to the wall or spillways needs prior permission; the lake, its shoreline and several picnic spots nearby do not.

What Tarbela Dam is
Built between 1968 and 1976 on the Indus River as part of Pakistan's response to the 1960 Indus Waters Treaty, Tarbela is an earth and rock-fill dam roughly 143 metres high and nearly 2.75 km long, holding back a reservoir, Tarbela Lake, that once stored over 11 million acre-feet of water, though decades of silting have reduced its live storage significantly. Its power station has an installed capacity of 4,888 MW, generated through 14 units, and a fifth extension project, adding a further 1,530 MW, has been under construction since 2021.
The dam sits close to the town of Ghazi, on the boundary between Haripur and Swabi districts, and is run by the Water and Power Development Authority (WAPDA), which also operates the smaller Ghazi-Barotha hydropower project a short distance downstream.
What you can see without permission
The lakeside around Tarbela has public parks and picnic areas that are open to ordinary visitors, with views over the reservoir and, from some spots, the dam wall itself. In summer, when the spillways are opened to manage water levels, they are visible from these viewing areas and are one of the more striking sights here: a genuinely large volume of water being released. These areas are the practical option for most families and day-trippers, and they need no advance arrangement beyond turning up during daylight hours.
Getting permission to visit the dam itself
A closer visit, to the dam structure or the powerhouse, is a different matter. This is an active, secured national infrastructure site, and WAPDA requires prior permission before anyone is allowed near the powerhouse or the dam crest. In practice this means contacting WAPDA's public relations office in advance, in writing, and explaining who you are and why you want to visit; approval is not guaranteed and can take time to come through. This is not something to plan for on the day, and it is not a realistic option for a casual family outing. If your interest is professional or academic, such as an engineering study visit, apply well ahead through WAPDA's official channels rather than trying to arrange access on arrival.
Getting there
Tarbela is reached from Haripur via Ghazi, on a road that also connects to Havelian and, further afield, Abbottabad. From Islamabad, it is a drive of a little over two hours by road. It pairs naturally with other stops in Haripur district; our guide to places to visit in Haripur covers Khanpur Dam and other nearby spots for a fuller day out.
Is it worth the trip?
For anyone interested in engineering or simply the scale of the structure, the lakeside parks make a worthwhile stop, particularly in summer when the spillways are running. Don't build a day around getting inside the secured area unless you have already arranged permission with WAPDA; for most visitors, the public viewpoints are the realistic and enjoyable option, and they need no paperwork at all.
Frequently asked questions
Can I visit Tarbela Dam without permission?
You can visit the public lakeside parks and viewpoints without permission. Getting close to the dam wall or powerhouse requires prior approval from WAPDA.
How do I get permission to see the dam up close?
Contact WAPDA's public relations office in advance, in writing, stating your purpose. Approval is not automatic and should not be assumed before your trip.
Is Tarbela Dam near Islamabad?
Yes. It is roughly two hours by road from Islamabad, via Haripur and Ghazi.
What is the best time to see the spillways open?
Spillways are typically opened in summer to manage high water levels in the reservoir, and this is when they are most visible from the public viewpoints.
Is Tarbela Dam the largest dam in Pakistan?
By height and reservoir volume, it is one of the largest earth and rock-fill dams in the world and the largest of its kind in Pakistan, though Pakistan has since begun building the larger Diamer-Bhasha Dam further up the Indus.
