There are two ways to reach Dizin from Tehran. The longest and safest way is through Karaj, this road is usually open but it takes about 2,5 hours. The quickest way is directly north passing through the resort of Shemshak. Between Shemshak and Dizin the road is steep and frequent avalanches means this part of the road often is closed. The minibus mentioned above use this way - Unless you are on a day-trip it is strongly advised you take the road through Karaj.
Make sure you check the weather and snow forecast before you leave, especially if are traveling the direct route.
The hotel is located just 20 m from the bottom of the slopes. The parking area is just 50 m away with a few shops that rent out ski equipment. See the map for further details.
You can see Mount Damavand, the highest mountain in Iran, from Dizin. The scenery with the surrounding mountains is spectacular.
Dizin is an excellent place for skiing and snowboarding, with 22 lifts in the area. A day pass costs between 120,000 and 150,000 rials (more on the weekend). A snowboard can be rented for 100,000 per day, but can go as high as 300,000 per day depending on where you rent and quality. Cheaper rentals are available in Shemshak or at the parking lot on the top of Dizin.
It is possible to rent ski and snowboard equipment at three places: the pro-shop at the Hotel which has the newest great and thus much more expensive, the rental places around the parking lot by the hotel and a few small places along the road at the parking lot on the top. The latter is about half the price compared to the ones at the bottom of the slopes. Same applies to rentals in Shemshak.
Ski instructors are available for hire. It is also possible to hire an experienced guide who can take you to other mountains and off-piste skiing.
During the day there is a SFC (Iranian version of KFC) in the middle of the slope and a snack bar at the top. The latter also serve breakfast.
At night there are only two restaurants (also open for breakfast and lunch); one in Dizin Hotel and another in the other hotel (only restaurant is open).
There is also a hotel in Shemshak from where you can catch a ride or a taxi to the top of the slope. Next to Dizin Hotel 1 there is another hotel with the equally creative name Dizin Hotel 2. However as of 2008 it was undergoing renovations and only the restaurant was open.
There is no public telephone in Dizin. Irancell mobile network has coverage (early 2009). You may also be able to use the phone in the reception of Hotel Dizin for local calls.
You can get a taxi from the top of the slope down to Shemshak which is another ski resorts just 15 minutes away. Shemshak is steeper and very good for experienced skiers.
