The Kuala Perlis Bus Terminal (Terminal Bas Kuala Perlis) is located close to the jetty where regular fast passenger ferry boats and car ferries travel over to the island of Langkawi.
If you want to travel to Langkawi by bus, this is the most popular departure point, as it is the shortest distance from anywhere on mainland Malaysia to Langkawi, with boats from Kuala Perlis to Kuah taking just one hour and 15 minutes to get to Kuah Jetty on Langkawi Island (Pulau Langkawi).
When you get to the bus station in K. Perlis, it only takes you a few minutes to get to the ferry terminal (Jetty).
Just walk to the end of the bus parking area (away from the bus ticket counters) and there is a covered walkway that takes you between the buildings.
When you come out the other side, you will see the ferry terminal on your left, just across the road.
Tickets for the ferries are sold from tickets counters just by the front entrance to the waiting area (outside the terminal building).
If you want to stay the night, there are a number of hotels located near the jetty area.
This is not the busiest bus terminal you will come across on your travels in Malaysia and there are limited departures to the following popular destinations:
Another option is to go to the nearby Kangar Bus Station where there are much more frequent departures.
To travel from Kuala Perlis to Kangar you can either take a taxi or get one of the Maraliner buses that leave from K. Perlis to Kangar.
Or you can ask one of the long distance buses to take you there (costs around 5 MYR - they will not sell you a ticket at the counter - you just have to ask one of the bus drivers).
If you want to travel from Kuala Perlis to Thailand by bus, you will first have to go to Kangar, then take another Maraliner bus from Kangar to Padang Besar.
