Staying in Brighton
If you are staying off-campus during your visit, then the best ways to travel to the university each day are either via Train from Brighton station travelling to Falmer station, or taking the number 25 or 23 Bus which travels right up to the department. Brighton's buses are generally quite good and frequent. You can buy a ticket from the driver, or if you are staying for longer you can buy a season tickets on their bus-keycard or mobile app from here: Brighton buses.
