Lots of events and meet ups here on TT to start with.
Try and find people with similar interests.
Will you be working during your gap year? I assume you are about 18? Don't know how many expats are here on their own of a similar age and I guess to meet the locals, you will have to do whatever if it that young people do!
I know nothing about
Laim and travel times, it will all become apparent once you get here...
Post some more info about yourself in your profile too. It might encourage people to respond and want to meet you
Good luck!
