You can go to any victory liner bus station and ride a bus going to Baguio. It takes about 6 hours to get to Baguio from Manila. Fare is 350-400.
There are so many cabs for going around Baguio. These are non-airconditioned since the place is blessed with a cool climate.
For Public transportation to Baguio, there are several bus stations. From Manila, you can take a Victory Liner Bus from Cubao (tel. no. 7274534, about P300). From Ilocos Sur, La Union you can take the aircon Partas Bus line (about P200) or any small busses plying the highway (about P60).
For those using private cars, you can take the Kennon Road from Rosario, Marcos Highway from Agoo
and Naguilian Road from Bauang . Just take care 'cause sometimes it's foggy specially during late afternoon. Sometimes, the highways have minimim visibilty so watch out for the curves.
For going around Baguio City, you can always take the ever reliable taxi cabs. The drivers of these cabs are friendly and they' always give back your exact change. You can also take the jeepney which is much cheaper.
The major roads around Baguio City is jammed with traffic during Baguio's peak seasons ( especially during the Flower Festival) so I advise you to either go to Baguio using public transpo or just avoid the major streets.
Except for the immediate downtown area, Baguio City is too big to stroll around. Jeepneys and taxis are available to take you to your hotel, or to provide transport in and around Baguio City. Taxi drivers will swarm you at the bus and air terminals, so it's not a surprise to learn that many also lend their services as tour guides. Locals on hotel-commissions will also descend upon you even before your feet hit the ground, so if you arrive without a hotel reservation, you can tempt fate or, if you're arriving at the airport, you can consult the people over at the tourism information counter.
An easy way to go to Baguio is to ask my friend and former flight instructor Capt. Mike Gomez to fly you with a small aircraft. Enquiries please to http://www.omniaviation.com.ph/about.html
I flew with Asian Spirit to Baguio from Manila and despite the suffering you go through at Manila domestic airport the flight was well worth it
Kennon Road is the old route up the mountain to Baguio. It's been replaced by the Marcos Highway as the principal route in and out of the city.
