Shemshak is the second largest ski area in Iran after Dizin and came into operation in 1958. It includes two ski lifts, three dish teleskis and two Hammer teleskis. The slopes lie at an altitude of 2550m to 3050m above sea level. The resort includes two main slopes each with a chair lift that apex at the top and several lifts. There are also lighting facilities for night skiing.
Shemshak has classically catered to more advanced skiers while Dizin has drawn Beginner and Intermediate Skiers. The slopes are quite steep and many of the runs are mogul runs.
Shemshak is conveniently situated just about 55 minutes drive from Tehran, 10 km from middle-slope parking of Dizin and 5 km from Darband-Sar ski resort
There are rumors of public transport (savaris and minibuses), although these do not seem to depart from Tehran's Eastern Bus Terminal as suggested by the most recent edition of the Iran Lonely Planet. A knowledgeable young local may be able to assist.
You're obviously here for the snow, right? Shemshak is far less crowded than [http://wikitravel.org/en/Dizin Dizin], although is smaller and caters more to more advanced skiers (and some snowboarders).
Currently, a lift daily lift pass (the only ticket option) is 150,000 IR. Trail maps seem rather scarce, although a number of websites have produced their own (see, for example, [http://www.snow-forecast.com/resorts/Shemshak/pistemap snow-forecast.com)].
Rental prices vary, but a decent set of skis, boots and poles can be found from 150,000 IR. Quality varies widely, so it pays to look around first. Surprisingly, the smaller rental operators closest to the main entrance seem to have better equipment and prices.
Options are fairly limited, although there are "Boof" (McDonalds + KFC) and "Super Star" (Hardees + KFC) fast food outlets. Both are located along the main road that passes the main entrance of the ski field.
A small bakery is located between these two fast food outlets, although it tends to only operate until around the early afternoon.
There is only one official hotel in Shemshak:
Some travel guides also discuss the possibility of apartment rental in Shemshak. Given the large number of apartments (completed or under construction) this would be a better option for larger groups. Local agents do not seem to advertise, although reputable travel agents in Tehran may be able to assist.
A few taxis will hopefully loiter at the ski field entrance at around 3:00pm, although be prepared to bargain hard. With some luck, you may befriend some of the locals and find someone going back to Tehran that afternoon.
Further 15 minutes up the road you reach the top of the slopes of the ski resort in Dizin.
