Tagaytay is an hour and 15 minutes drive from Manila via the South Superhighway or through the Coastal Road. If going through the South Superhighway, take the Carmona Exit and drive down through the Governor's Drive and Silang up to the entrance of Tagaytay City. Or through South Superhighway, take Sta. Rosa exit going straight to Tagaytay City.
There are two possible ways to get to Tagaytay via the Coastal Road: Indang and Mendez Roads on Trece Martirez and Amadeo areas. If coming from the neighboring town of Ternate, Cavite take the Naic road and drive straight to Indang and Trece Martirez. From Batangas Province, the best way to reach Tagaytay is through the new circumferential road. From Laguna, you may enter Tagaytay through the Carmona exit. There are buses and vans that ply to Tagaytay from Manila on a daily basis from 6:00 AM to 9:00PM. The CELYROSA, CROWN, and other bus companies have their terminals in EDSA, Pasay City,Lawton and at Baclaran.
Tagaytay City is pretty much like a small town than a city. A single road by the ridge, no more than 8 kilometers from end to end (People's Park to Residence Inn), is where almost all the activities are happening. The most convenient mode of getting around is by car. Public transpo (jeepneys and trikes) is likewise convenient.
Getting there by car: If coming from Manila, take this route -- Roxas Boulevard --> Manila-Cavite Expressway (more popularly known as Coastal Road) --> Emilio Aguinaldo Highway.
The end of Emilio Aguinaldo Highway is the main rotunda of Tagaytay City, where the statue of Ninoy Aquino is erected and bounded by establishments such as BPI (Bank of the Philippine Islands) and 7-11.
Another option is to take the South Luzon Expressway (currently undergoing expansion) and exit at Sta. Rosa. Turn right upon leaving the Sta. Rosa toll and head straight to Tagaytay City. That road is the Sta. Rosa-Tagaytay National Road which ends at the rotunda near Tagaytay City Public Market. Turn right to get to the main rotunda.
Trip duration: about 1-1/2 to 2 hours
I just found out that there are fx jeeps at the Starmall in Mandaluyong. They're parked alongside EDSA and there are those bound for Batangas (Lipa, Batangas City, etc.) and Tagaytay. It will be cheaper to use the public transport but you may have to bring a lot of things so it might be practical to rent a vehicle.
Going to Poeple's Park in the Sky, Tagaytay Highlands, Good Shepherd Convent, Picnic Grove, Development Academy of the Philippines, Nature's Park, Tagaytay Japanese Friendship Garden, Tagaytay Gymnasium: ride the jeep bound to People's Park in the Sky at the Olivarez Plaza. Fare is 15 pesos each.
Going to Dencio's, RSM, Leslie's, Josephine's, Starbucks, Kitaro, Mi-Jo Hotel, Mahogany Market, Tagaytay City Hall, Tagaytay International Convention Center, Taal Vista Hotel, Mushroom Burger, Bag of Beans, Caleruega, Residence Inn Hotel: ride the jeep bound to Nasugbu. Minimum fare is 7 pesos each.
The Crow/Crown Bus Lines is the most trusted when it comes to public transport going to and from Tagaytay. The buses going to Batangas usually pass through Olivarez Plaza, Tagaytay City. It is located near the MRT Taft Avenue Station, behind the building where a Chowking restaurant is situated. One-way fare to Tagaytay costs less than a hundred pesos.
Going to People's Park in the Sky, Picnic Grove, Good Shepherd Convent (for pasalubong!), Tagaytay Econo-Inn, Royal Taal Inn, Keni Po, Aroma Apartelle, Amora Rooms, 5R, Devt. Academy of the Philippines, Japanese Garden, Tagaytay Gymnasium... go to the jeepney terminal @ Olivarez (just a wee bit before the Olivarez Plaza if you're coming from Manila). Take the jeep bound for/with the signage People's Park in the Sky.
Going to Bag of Beans, Caleruega, RSM, Mi-Jo, Leslie's, Starbucks, Kitaro, Josephine's, Parc Royal, Tagaytay Int'l. Convention Center, Mushroom Burger, Rancho Ferva Lodge, Taal Vista, Residence Inn, Tagaytay City Hall, Mahogany Market, 41st Division USAFFE site... take the jeeps bound for Nasugbu or Mendez.
For those who want to get the freshest beef to take home, you can go to Mahogany Market.
At the Olivarez Plaza you can find there's a drugstore, grocery, photo supplies shop, ATM/banks, ukay(thrift shops) and fast food restos.
At the People's Park in the Sky, there are restos, souvenir and food shops. When going back to Olivarez from there, wait for the jeepney going down the park. The driver will drop you off at the terminal, then from the terminal, you can get a ride going back to Olivarez.
Although you can ride a tricycle, they ask for a higher fare. 3X the jeepney fare, actually.
Although it is possible to travel from Manila to Tagaytay by public transport, it may not be very safe to do so unless your local friends are bringing you there. A safer but more expensive option will be to book a day tour (about US$100-150 depending on itinerary) or overnight tour where you have your own transport and driver, which offers safety and flexibility. To lower the cost, you can form a bigger group as the cost is per vehicle and driver. Day tours can be booked via the internet or while you are in Manila. VT member jasmine_trias is working in a tour agency in Manila and she may be able to help you.
there are other bus lines that would take you to tagaytay but i've been using the "Crow" ever since..... fare is around Php70-80 (sorry. forgot the exact fare)..... the terminal is at taft-rotonda..... at the side where the wendy's/chowking is located...... it's along edsa....
If you want a good FX driver in the Manila area, call Arnold Martin (Cell: 09208157511). He drives a Toyota Revo, which is a small SUV. He charged 2000 pesos plus gas for the first day to Tagaytay/Talisay and just 1000 pesos the second day. He was going to sleep in the FX Revo but a room was only 400 pesos at the Villa Amparo Resort in Talisay, so it was my treat. Not only is he a good driver, he is a pleasant person to be around. We chatted about all sorts of things...people, the Red Queen effect, traveling, etc.
