To get from Penang to Kangar you can take a bus from Penang Sentral Butterworth or Sungai Nibong, or you can take a train to Arau, then a short bus ride to Kangar on a MyBas service from just in front of the KTM Arau Railway Station.
The most direct way to travel to Kangar from Penang is to take a bus from Penang Sentral Bus Terminal in Butterworth to Kangar Bus Terminal (Terminal Bukit Lagi).
Buses operated by Plusliner, Maraliner and Kesatuan Express depart from Penang Sentral to Bukit Lagi Kangar.
The duration of the bus trip from Butterworth to Kangar is around 2 and a half hours.
Bus tickets from Penang Sentral to Kangar cost from around 15 RM to 20 RM.
Another option is to take the bus from Sungai Nibong Bus Terminal on Penang Island to Kangar (if you are staying in Georgetown we would recommend taking the ferry to Butterworth and taking then the bus from there).
Plusliner buses operate from here to Kangar.
To get to Sungai Nibong from Georgetown you will have to take a RapidPenang Bus or a taxi.
The bus trip from Sungai Nibong to Bukit Lagi in Kangar is a little longer from here and cost a little more with ticket prices at around 18 RM.
If you want to find the cheapest way to get from Penang to Kangar, travelling on a KTM Komuter train from Butterworth is the way to go.
From Butterworth Railway Station take a KTM Komuter train to Arau.
For the latest Komuter train timetable see the following link:
Once you arrive at Arau KTM train station, there is a bus stop near to the station exit where MyBas buses stop on their way to Kangar.
If you are lucky and don't have to wait for a bus at Arau train station for too long, it can take around the same time as taking a direct bus and save you a little money as the total cost of travelling this way is around 13 RM.
If you want to travel by train from Butterworth to Arau in a little more luxury, there are also the KTM ETS (Electric Train Services) on this route.
They are much more comfortable as you get an allocated seat (unlike the Komuter trains where seating is on a first come, first served basis).
They do however, cost quite a bit more on this relatively short trip.
