Arrival at the international airport:

If you arrive by plane, go through the immigration procedure: Fill in the small form called TOURIST CARD, provided to you on the airplane. As albanian, australian, canadian or mexican citizen you have to pay a reciprocity fee for entering to Chile, payable with credit card or cash in US-dollars (you will get a stamp in your passport allowing you re-entry without paying again as long as you use the same passport). Then stand in line and show your passport and the tourist card to the officer. You will get back a transcript of the Tourist Card which is needed when you leave the country, so keep it safe.
Australia US$ 61
Albania US$ 30
Canada US$ 132
Mexico US$ 23 
After passing through immigration, collect your luggage and head to the Customs and SAG controls. Your luggage will be inspected for certain goods, since it is not allowed to bring any vegetable (fresh or dried fruits and nuts, honey, wood, plants, flowers, seeds) or animal products (meat, eggs, milk products, cheese, unprocessed wool or leather) into the country. Please make sure to eat or dispose all those products before landing. (Only possible exceptions are industrially processed and air-tight sealed products which have to be shown to the officer.) You have to fill in a SWORN STATEMENT declaring that you do not bring any of those (if you do, you have to check the corresponding boxes) and you will be questioned about the content of your luggage by a SAG inspector. After the SAG inspection head for the exit. 

Transfer Airport – Hotel or Pontificia Universidad Católica de Chile (Vicuña Mackenna 4860, Macul):

For going from the airport to your hotel there are three options: shared shuttle, private taxi, and bus+metro. The prices are around 8000 CLP (US$ 11), 20000-30000 CLP (US$ 28-43), and 2000 CLP (US$ 3), respectively. The official companies for shared shuttle and private taxi are Transvip and Taxi Oficial, and for bus Centropuerto and Turbus. 
It is possible to reserve a ticket in advance, and  then just specify your name and reservation code (código de reserva) to get your ticket, see for details.
DO NOT accept the offer of an unofficial cab driver (prices are way too high and some of them are not trustworthy). 

Note: In Chile it is not common to tip a cab driver


Chile´s currency is the Chilean peso (CLP). Exchange rates are roughly: 750 CLP = 1 US$ (actual rates can be found on 
Note: Small shops are unlikely to accept 20,000 CLP bills, so always try to have enough change. Also for a taxiride it is recommended to have change.
Using your credit or debit card you can obtain CLPs from any ATM which can be found in banks, Metro stops, supermarkets and most pharmacies.

Getting around town – getting to Pontificia Universidad Católica de Chile (Vicuña Mackenna 4860, Macul):

For maps of Santiago use or just Google maps. 
To use Metro or buses in Santiago you must have a  BIP card (Tarjeta BIP) which can be purchased for 1,500 CLP (US$ 2.1) at the central information stand in any Metro station. The cost of each trip is between 750 and 830 CLP depending on the time of day (more expensive during rush hour). You need to charge your BIP card with a sufficient amount before using it. This can also be done at the main stand of any Metro station or at designated machines in each station. Recommendation: Charge the card with 5,000 CLP, enough for several trips, but not too much in case you lose the card. 

Metro (subway): 

The easiest and fastest way to travel in Santiago is by Metro which runs Monday to Saturday between 6:30 and 23:00, on Sundays and public holidays from 8:00 to 22:30. Rush hour is from 7:00 to 9:00 and from 18:00 to 20:00 and Metro really gets crowded during these periods. There are 4 lines (red=1, yellow=2, brown=3, blue=4, green=5, purple=6 ) that connect basically all important parts of town. Trains run every 2-3 minutes during the day and every 3-5 minutes at secondary times. 
San Joaquín station (green line, 5) is the closest metro stop to Campus San Joaquín (Pontificia Universidad Católica). A global map of the subway can be found here
The location of the Facultad de Matemáticas within the Campus may be found here map
If you are staying at a hotel/apartment in Providencia near Hotel Bonaparte walk to Ines de Suarez Station (in Pedro de Valdivia with Francisco Bilbao), take line 6 in CERRILLOS  direction, then transfer in ÑUBLE station to take line 5 in VICENTE VALDES direction and go out at San Joaquín station.

The whole trip should be around 45 minutes. Look at the map for directions.


In addition to Metro, Santiago is covered by a large bus network. Buses run a fixed route and show the corresponding line number and important stops on a front-screen display. To pick up passengers they only stop at «paraderos» (bus-stops) showing the corresponding line numbers. See departure/arrival times of buses at, frequency is high, so you probably have to wait no more then 10 minutes during day-time. Standing at a larger bus stop (with more than one line) it is common to wave your hand to signal the driver that you are interested in boarding his bus. Note: If you are not sure about the route, ask the bus driver.
The BIP card allows you to make connections to other bus or  Metro within 120 minutes without extra charge (except during rush hour, when you have to pay an additional 60 CLP for the Metro). 
Note:  You can not charge your BIP card neither at a bus stop nor inside the bus, so remember to have enough money left on it for your bus trip.


Taking a cab within the city is safe and not too expensive. You will see those black cars with a yellow roof picking up and delivering passengers everywhere. To take one yourself just stand next to a busy street, wait for a taxi passing by and wave your hand to stop it. Usually taxis signal availability with a red neon writing «libre» on their windscreen and they have the price written on a sticker on the windscreen as well. Standard charge is 350 CLP base fee plus an additional 130 CLP for every 200m resp. every minute. Check the price, enter the cab and tell the driver where you want to go. It is helpful if you know the route yourself, as some taxi drivers do not know all the (smaller) streets and of course this way you can check that the driver uses the shortest route. During the trip make sure the taximeter (in right upper corner of windscreen) is on and working correctly. Some taximeters count twice as fast (they jump 260 CLP at once), so if you notice this tell the driver to stop and leave. On arrival pay with small bills as most taxi drivers are short on change. Overpaying the actual price with a large bill, there also is a slight (rare) chance that you will get back false money.


In January day-time temperatures in Santiago will be around 30 ºC, night-time temperatures between 15ºC and 20ºC. Probability of rain in Santiago at this time of the year is very low. For more details consult:


In Avenida Providencia  there are a lot of restaurants, however demonstration tend to be in Av. Providencia and Bdo. O´Higgins (known as Alamenda). Since taxis are safe and relatively cheap we recommend going to the Plaza Ñunoa area, to Manuel Montt area, close to Ines de Suarez Station, or Av. Italia area. 
Here, you will find several restaurants near Providencia neighborhood

Lunch time starts around 13:00, dinner time is around 19:30 until 23:00. Most restaurants are closed Sunday evenings. The standar tip is 10% of the bill.
