Thira is built on the cliff
Fira (also called Thera or Thira) is the main town of Santorini island. Though it has little except the museum, the cable car and the few bars and clubs, it is a good base to use as there are buses from many other parts of the island.
Every day during the summer is a bustling metropolis as cruise ships from all over the Mediterranean and Aegean seas descend. As a result prices in Thira (and Santorini generally) tend to be a little higher than other Greek Islands.
Information on how to get into Santorini can be found here.
From Santorini airport: by taxi, or shuttle bus 
From the old port, where cruise-ships arrive: by cable road, donkey or by foot.
Fron the new port (Athinios), where all the ferries arrive: by taxi (expensive) or by local bus (2€, can be crowded), or by shuttle bus , value for money
The main bus station of Santorini is in Fira, where you can catch a bus going almost anywhere on the island, usually hourly (every 30 minutes on 6/29/2009). The schedules are posted here daily. Up the stairs behind the bus station and across a parking lot to the west is the main taxi stand.
A public restroom is located at the southern end of the taxi stand. There is a crazed woman who confiscates the toilet paper from the toilets in the mornings, and then accosts patrons as they enter, demanding 50 euro cents for a couple of sheets of toilet paper. She follows people into the restroom and continues to harass them while they use the facilities. Bring your own napkins, and try to ignore her.
Another great way to get around the (small) island is by hiring a quad bike (usually named "ATV") from numerous locations in the main tourist villages. for €20 a day, it is better value than taxis and more fun than a bus.
- Definitely pay a visit to the Museum of Prehistoric Thira, where the story of Akrotiri and other ancient settlements is vividly told through a stunning collection of Neolithic and Bronze Age artifacts. (free for students) Special ticketing package for the Archaeological Museum the Museum of Prehistoric Thera and the Archaeological Sites of Akrotiri and Ancient Thera: € 8 (reduced: € 4).
There's actually not a lot to do in Fira. Apart from the few museums and craft studios (which are open fairly late), travelers seeking unique experiences unobtainable elsewhere will be disappointed.
- Stroll through the shopping district (for overpriced jewelry, designer clothing and handbags) and go to the numerous (American-styled) discos and bars.
- Watch a sunset over dinner.
- Walk along Agiou Mina street. This street goes through Fira part-way down the cliff, from the south part of town all the way to the cable car. It provides the stunning views of Fira that you came to see. You can walk either north or soth, but walking north has the advantage that the main part of Fira is in front of you. To get there, from the the main cathedral, walk with the sea to your right, just left of Hotel Atlantis, about 50 m. Walk around 1500 BC restaurant, and you'll be on the path. Just be careful of the donkey poop!
- Go to the Old port. Whoever said "Getting there is half the fun" was likely referring to the Old Port. Or, in this case, getting there is 99% of the fun. There is almost nothing to do at the Old Port (except perhaps take a couple of pictures from sea level). But the ride down and up can be fun. Your choices are the cable car (€4 one way), donkey ride (€5 per person, plus a €5 "tip" for your "guide"). Walking is possible but not very pleasant, thanks to the donkey excrement covering the path; moreover, donkey drivers are bent on making life difficult for tourists who refuse their business, so donkeys are not at all encouraged to avoid people while walking up or down. If you want to avoid the smell and the scene just take the cable car; even though the line may seem long sometimes (especially when people from the ferries arrive and leave), it moves pretty fast (36 people every 6-7 minutes or so). Some local mule guides may also try to cheat you by demanding a payment for walking down, they will try to sell you a small piece of paper that says ticket without any numbers on it. Ignore these people, the road is free. They will also try to convince you that the walk down takes one hour; it's a lie, it doesn't take more than 20 minutes, even zig-zagging to avoid the donkeys and their poo.
- Get out of the tourist section. The tourist part of Fira is surprisingly small; a couple minutes walk away from the sea brings you out of the tourist area. While the architecture here is not stunning, it certainly is different than you will see elsewhere. Plus, you'll have a chance to marvel at the fact that even though Fira land prices are very high, there are still empty lots in the middle of the city.
