Getting to and from Victoria: 

If you are coming from a long distance, the best way to get to Victoria is via the local airport, Victoria International Airport (YYJ).  You will likely want to arrive on the Friday.  Be aware it is difficult to get to the east coast of Canada or the States on a Sunday if you depart in the afternoon.  Quite often we have to resort to red-eye flights.

From Vancouver, the cheapest way to get to Victoria is by the bus. There is also a ferry, a harbour plane, and a helicopter service.  The bus drives onto the ferry -- it is the most relaxing way to arrive on a budget.  The harbour plane and helicopter service land near the downtown hotels, but have restrictive hours. 

If you are driving from the States, the Port Angeles ferry is likely the best option.  There is also a pedestrian ferry from Seattle. 

Transport inside Victoria: Be aware taxis in Victoria are relatively expensive.  A ride from the airport to your hotel will cost between $60 and $100.  The airport shuttle is far more cost-effective.  From the airport you can buy your ticket without reservation.  For the return trip, you book through your hotel.  Taxis between the airport and UVic usually cost between $40-$50. 

Getting between the centre of town and the university is an approximate 20-minute bus ride. Busses regularly depart the corner of Douglas and Fort (near most downtown hotels) in the north and east directions for the University.  All busses that stop at UVic say "UVic" on their fronts, and UVic is their final stop. 

Hotels: Popular hotels in the Victoria area include the Marriott,  Swan's HotelChateau Victoria, the Delta Ocean Pointe, the Coast Harbourside Hotel and the Hotel Grand Pacific.
