L'Aquila is an Italian city of about 70,000 inhabitants and nearly 30,000 university students. It is the capital of the Abruzzo region and it is conveniently located 100 km (62 miles) to the east of Rome. The city is on a hill at 720 m (2365 ft) above sea level and is surrounded by mountains, most notably to the north by the Gran Sasso range, which includes the highest peaks (up to 2900 m) of the Apennines, with a number of small lakes, trails and mountain climbing routes as well as deep caves. Within the province of L’Aquila there are also two national parks (Parco Nazionale Gran Sasso Monti della Laga and Parco Nazionale della Majella).
The city itself is full of history, traditions, beautiful buildings (like the Spanish Fortress) and churches (like the Basilica of Collemaggio). There are also a lot of good restaurants, pubs and places where students get together every night. The city is also home to L'Aquila Rugby: this team won the Italian championship five times!

There are three bus companies operating in L'Aquila that you will find particulary usefull in your everyday life
Besides these busses, there are also
The public transport in L'Aquila is covered by the AMA bus company. Depending on how busy the trip can get thet run orange/blue/green/black busses "l'autobus" or blue vans called "pulmino".
The final destination of the bus is always written on the front side of the bus and together with the bus number can be seen from far. You need to get used to the way the timetable is written, as you can either search for number, or the bus stop (not for the time or "from-to destination trip"). To search for the time online, please check the name of your bus stop and then search for this destination in Linee e Orari to find the bus number you need to take. The other way is to search for the number and then check where it goes. Moreover, there is nowadays nice and clear time table on every bus stop. You can find the map of lines here.
You are obliged to enter a bus with a ticket and validate it in the yellow machine inside the bus. The complete list of ticket selling places can be found here. The closest one to university Coppito is Self copy SaS di Epifano - just across of the road from University. Please mind, that not every place sells all types of tickets.
Here are the most useful types of tickets with prices:
The controllers occasionaly get on the bus and wear the dark blue company clothes. They don't speak english and the fine for not having a validated ticket can get up to 160 Euros.
* the same system as for Arpa holds here as well: in order to be allowed to buy the montly ticket you need to register and buy a card at Terminal Bus Station or Sangritana Viaggi e vacanze Fontana Luminosa. You need to fill in a form and bring ID or passport and 2 passport size fotos. The card is valid until you lose it and costs around 15 Euros.
Regional public bus transport is run by the Arpa company - blue or white with blue stipes busses.
It is the bus company you will use daily for reaching the University. For more information about this daily routine see this article about transfer between L'Aquila and Pizzoli, or how to get to Rome from L'Aquila.
Timetables for other Arpa rides can be found here.
Arpa is the intercity Abruzzo regional bus company that offers transport within the region and also runs to Rome. It is the best option for Rome trips (11 Euros one way). Their offices can be found in several places, moreover, it is possible to buy a ticket at every SISAL place - for example at the Bar in Motel Amiternum.
As for Pizzoli - you can get the tickets in every bar in Pizzoli. For Pizzoli - L'Aquila trip the ticket Tariffa 2 is needed. You are obliged to validate it in the machine inside the bus.
You'll find all Gaspari timetables on their webpage. There are 2 lines that might be on your interest:
Gaspari tickets can be bought both, on the bus and online. Their page hasn't been translated into english yet but this article describing how to buy tickets on gaspari webpage in english might be useful. We recommend to buy your ticket online, so you assure yourself with the seat on the bus in case it gets busy (which has recently been happening). When entering the bus, pasangers with online tickets go first.

L'Aquila can be reached either via motorway or road:
There is only one taxi company in L'Aquila, Radio Taxi. They can be reached by phone +39086225165 or in front of Motel Amiternum.
Erasmus Mundus students are meant to get the special price of 15 Euros for the trip Pizzoli-L'Aquila and vise versa. The usual trip Motel Amiternum-city center is aroun 4 Euros.
Radio Taxi are available every day until 12am; on Thursdays and Saturdays until 3am. Aside from these times it is possible to make a pick up agreement in advance, however, if you have a early flight (therefore early gaspari bus) we reccomend to stay at friends place in L'Aquila for this special occasion.
Students often use auto rental services for weekend or daily trips. There are several car rental company, just search for 'car rental in L'Aquila' in your browser or ask older students.
In 2014 there were students renting a car from Europcar, na Via della Croce Rossa. For approximately 2-4 days it was around 30 Euros a day but drivers under 25 have to pay an extra fee.
Aquilasmus is a student association, part of ESN (Erasmus Student Network).

Before the 2009 earthquake most people and students used to gather at the many cafes and bars in L'Aquila city centre. Now, while most buildings there are still to be reconstructed and great part of the area is not yet accessible to people, a bunch of bars have proudly reopened their doors. You will find lots of students hanging out mostly on Thursday nights (typically, university night) and Saturday nights. Just ask the taxi/bus driver to drop you at "Fontana Luminosa" (the big fountain near the castle) and walk into the main road "Corso Federico II". You'll see that most people gather in that small square or head right into via Garibaldi. As a consequence of the earthquake, several other good pubs and clubs have had to move to other areas of the city. So, take a look at the rest of list, too.
City centre
Viale della Croce Rossa
After the earthquake several pubs moved from the city centre, which was off-limits for several months, to this road which connects the "Fontana Luminosa" to Viale Corrado IV
Between the train station and Viale Corrado IV
Viale Corrado IV (main road connecting Hotel Amiternum to the city centre)

Thanks to the great geographical location, both, L'Aquila and Pizzoli offer great oportunities to hike or just go for a nice walk into the mountains or woods.
All Pizzoli hikes start at the 'Pizzoli castle' when you continue up the road and after you pass few houses you will find yourself in the nice Abruzzo woodland.
As for L'Aquila hikes, you may pick any hill you see from the center
It is quite likely to meet horses, cheep, cows or even some wild animals on your way - all being more scared than yourself and therefore harmless. Sometime you may stumble across cheep dogs that might look angry but if you don't show any signs of agression and simply ignore them they will gladly return the favore.
Dispite having no cycle paths in L'Aquila, it is possible to cycle on the road, however, this is on everyones own responsibility. You can get propper cycling stufff in Decathlon in Laquilone or other cycling shops in L'Aquila. There is also an active cycling club that occasionally organises bike events in Gran Sasso .
