When flying over the country recently I studied for almost an hour the impressive mountains of Iran. Big and mostly empty of people.
That image by Views of the Earth is posted on an excellent website called Iran Nature.
All useful information you need to visit Iran natural and historical attractions and landscapes. Hiking & trekking Iran nature and ecosystem, Iran mountain, valley, and cave, Iran forest and garden, Iran plain and desert, Iran lake, river, spring, and waterfall, Iran protected and wildlife zone, Iran island.
The most popular adventure in Iran is climbing Mount Damavand, the highest peak 5671m (18,605ft). It’s near Tehran.
Personally I’m more interested in hiking opportunities. But I cannot find much information on the web. Leave a comment if you have any advice about trekking in Iran.
President Mahmoud Ahmadinejad has many problems these days. Too many problems to think much about the 3 American hikers who entered Iran illegally, accidentally, from Iraq.
He did say that he hopes the punishment dealt out by the Iranian judge is not too severe.

Hi,
Not 100% mountain but definitely 100% Iran:
Mark Kalch, an Australian adventurer based in the UK is currently walking solo in Iran from north to south.
He’s blogging when possible while trekking. Check it out at http://www.markkalch.com/expeditioniran – probably of interest to readers here.
Looks like a rewarding journey.

Thanks Nick. I’ll check out Mark’s site.

I suggest you to search about “Kermanshah” &”Lorestan ” mountains , “Persian Gulf” , ” Kavir e Loot ” , “Masooleh” village , …..
