Iran is an amazing place, and, as a U.S. Citizen, it is totally possible to travel to this country on tourism.
Foreigners of any country can go to Kish Island, Iran (a small island in the Persian Gulf) without a visa. I went there with a friend of mine back in 2010 and got a visa on arrival in about 30 minutes. You take Kish Airlines from the Dubai International Airport for the short flight (holding my breath the entire time because I felt like I was in a 1960s-style Soviet propeller plane) to Kish Island.
Upon arrival in Kish, you will be asked to show your passport and take a bunch of fingerprints. The guys at Immigration were very friendly and actually more curious than anything on why a westerner would want to travel to Iran.
The second and other route for coming to Iran as a U.S. Citizen is to get a visa for mainland Iran, including Tehran. There is the general misconception that you cannot travel there. Completely not true! While independent travel to Iran is forbidden, you can go through an approved travel agent or tour company in Iran who can get you the necessary paperwork you will need for the visa (which you will need to get in advance of your trip). In most cases, even though you need to have a tour guide, you will have plenty of time to stroll the streets and eat the local foods on your own when you want to.
Plan your trip and visa well in advance (I recommend 10-12 weeks) and have a healthy dose of patience.
The Ministry of Foreign Affairs in Iran will take up to 2 months (yes 2 months, so plan ahead!) to fax your visa authorization number to the Iranian Section at the Embassy of Pakistan in Washington D.C. or whichever Iranian consulate or embassy you selected at the time you submitted the form to your tour agency or guide.

Your tour group or travel agency will need to confirm if the Ministry of Foreign Affairs in Iran has already faxed your visa authorization number to your consulate/embassy.
