Simly Dam is a working reservoir on the Soan River that supplies drinking water to Islamabad, and it is not a fully open tourist site the way a park or viewpoint is. You can usually reach the area and see the lake, but it is worth knowing before you drive out that it is a functioning piece of city infrastructure first and a picnic spot second.
This guide covers what to expect at the gate, what you can actually do there, and why swimming is currently off limits.

Is Simly Dam open to the public?
Not in the way most tourist spots are. Because the reservoir supplies drinking water to Islamabad, the Capital Development Authority controls access around it, and visitors have reported being stopped at the entry point and asked why they want to go in. Most people who go for the day do get through, especially outside of any current restriction, but you should not treat it as guaranteed the way you would a public park.
The safest approach is to check locally, or with a hotel or local contact in Islamabad, before you make the drive, particularly if you are going specifically to see the dam rather than passing through the area for another reason.
Why swimming is not allowed
Simly Dam is Islamabad's largest reservoir of drinking water, so swimming and bathing in it work against the basic purpose of the site, and it has never been treated as a swimming spot in the way a river or a lake elsewhere might be. On top of that, the Islamabad Capital Territory Administration issued a two-month ban on swimming in Rawal Dam, Simly Dam, the Soan (Swan) River and nullahs across the capital from 8 September 2026, citing the risk from rain and flooding and past drowning incidents. Orders like this are renewed or lifted as conditions change, so check the current position before you go, and don't swim there regardless of what you read online, including here.
What you can do there
- See the lake and the dam structure. The setting, a long reservoir closed in by low hills, is the main draw, and it photographs well in the early morning or late afternoon.
- Picnic. Bringing your own food and eating by the water is the most common thing visitors do, and there is generally room to spread out away from the dam structure itself.
- Boating and fishing, where currently permitted. Fishing has historically required a licence from the Capital Development Authority, and boating availability depends on what the site is running at the time. Don't assume either is on offer; ask when you arrive.
- The CDA rest house. There is a small guest house at the dam, but it has only a handful of rooms, is intended mainly for government use, and needs prior permission and booking through the CDA. It is not something to plan around unless you have arranged it well in advance.
Getting there
The dam sits about 30 km east of Islamabad and Rawalpindi, and the drive takes roughly 45 minutes to an hour depending on where in the city you start and on traffic through the outer roads. A private car or hired car with driver is the practical way to go; there is no direct public transport to the dam site itself. Fill up before you leave, since fuel stops thin out once you're off the main roads, and go in daylight, since the roads around the reservoir are not well lit after dark.
Who this suits
Simly Dam works best as a quiet half-day out for people who want a scenic drive and a picnic by water, not as a swimming or watersports destination and not as a guaranteed stop if your day is tightly planned. Families looking for a reliable picnic spot with fewer access questions are often better served by Rawal Lake or one of the picnic spots closer into Islamabad, and can treat Simly Dam as a bonus if the access situation is favourable on the day. If you're planning a broader look at the capital, our Islamabad travel guide covers the rest of the city's parks, hills and lakes.
Frequently asked questions
Can I still visit Simly Dam?
Generally yes, though it is treated as a restricted site because it supplies Islamabad's drinking water, and you may be asked your reason for visiting at the entry point. Check the current situation before making a special trip.
Is swimming allowed at Simly Dam?
No. It is discouraged at any time because the reservoir supplies drinking water, and a specific two-month ban on swimming there, along with Rawal Dam and the Soan River, was in force from September 2026 due to rain and flood risk. Check current notices before you go.
How far is Simly Dam from Islamabad?
About 30 km, with a drive of roughly 45 minutes to an hour depending on traffic and your starting point in the city.
Can I stay overnight at Simly Dam?
Only if you arrange it in advance. The CDA rest house at the site has very few rooms, is mainly used by government staff, and requires prior permission to book.
Is there public transport to Simly Dam?
No direct public transport reaches the dam. Visitors go by private car or a hired car with driver.
