As with other places (not named Baguio City) in the Cordillera Administrative Region (CAR), trips to Kalinga are pretty hard to come by.
Here are the bus trips that you can catch to get to Kalinga:
Victory Liner (to Tabuk)
There are two daily trips out of Manila from the Kamias station of Victory Liner to the provincial capital Tabuk. The bus leave at 7:00 AM and 8:45 PM. You may buy tickets up to ten days in advance at the terminal. For seat availability concerns, you may call the Kamias station at (02) 920-7396.
The fare as of September 2010 was 493 pesos. The trip lasts around 12-13 hours and the bus makes four stops along the way.
The town of Tinglayan is about three hours away.
Cable Tours (To Bontoc)
Bontoc, Mountain Province is a major hub in the eastern side of the Cordillera Administrative Region. It serves as a major transit point to the other major towns in the region – Baguio, Banaue, Sagada and La Trinidad.
Bontoc is also only three hours away from the town of Tinglayan. This town is the one known for its tribal villages and age-old tradition of full-body tattooing.
Cable Tours has a terminal near St. Luke’s along E. Rodriguez Avenue in Quezon City. A night bus leaves at around 8:30 PM. The fare is a bit steep at 650 pesos for a 12 hour trip.
Once in Bontoc, look for the bus that takes you to Tinglayan. It should be down the road from where you got off from the bus. It is to the east. The bus is more of a mini-bus and by the time you get there, you would have to probably ride on top. The ride is rough and very scary.
The cost is 100 pesos and it lasts three hours – imagine being on top of a mini bus til noon-time. Slap on some sun block and watch out for power lines and tree branches!
There are probably more ways of getting to Kalinga through several cities like Baguio, Laoag, Vigan and Tuguegarao but coming from Manila is probably going to be a lot easier for most people. Please do share more information if you happen to know any other alternate routes.
