It would be possible to do 4 days from Lake Ovan to the Caspian hinterland via Khashechal summit( 4120 m). However, if you are to walk from the lake itself you really need 5 days of trekking plus the day to get there and to get to Tehran ie 7 days in total. If you wish to walk it in 4 days ie 6 days in total then you need to leave out the summit.
Another option would be to start from Garmarood, where the ridge is lower and the summit you can do is off the path and is 3600m. There is a dirt road that you will have to cross 3 times on foot and there will be some cars passing from May until October but this will be a short stretch.
You may end either in Maran or in Yuj.
The main differences between the two are the crossing of a road which is absent from the first trek, and the fact that the first trek goes through some of the most pristine Hyrcanian forests terminating at 900m ASL but in option 2 the trek ends above the forest line at about 2200mASL and the rest is in …
A few travellers have used banks to change money. This is a mistake as the banks will buy your foreign currency at a much lower state rate but will never sell you hard currency at that rate if you are left with the fast devaluing Iranian Rial, in fact the banks never sell hard currencies to anyone let alone foreigners so you lose out if you go to a bank! There are official bureau de changes where you can sell ( and only sometimes buy) your currency at the market rate. You can find them in most city centers as well as international airports.
You do not need Iranian Rials to enter Iran, USD and Euros are readily exchangeable in Iran.
Update September 2018
The currency situation is very unstable at the moment. The US dollar has gone up from 42000 Rials to 1 USD this summer to over 130000 Rials per 1 USD ( the euro being around 150.000 Rials per 1 euros at the time of this going to the press!!)
The advice is to exchange little by little.
The official bureau de changes which were closed …
Leave your prejudices where you live and come skiing in Iran !
Yes, we have ski resorts and when people are busy skiing in Iran, many European resorts are waiting for their first snowfall !
Besides, you pay embarrassingly little to ski in Iran.
Here you have a list of all the ski resorts close to Tehran:
1. Tochal Ski resort, this is the highest ski resort in Iran. It starts close to the summit at 3850m and is some 1200m long. It is skiable for almost 8 months of the year! It is a short car drive from central Tehran. http://tochal.org/en
2. Dizin, arguably the best ski resort in Iran, it is situated deep in the central Alborz range with spectacular views of the Alborz summits such as Alam Kooh and Mount Damavand. It is a 3 hour drive from the capital. There are 7500m of ski pistes from 3600 m down to 2650m of altitude.
3. Darband Sar is 50KM north of Tehran. It is a good resort for experienced skiers.
