Option #1 By BusThe following bus companies provide transport between Manila and Batangas, with Tagaytay CIty as a major stop. Please take note that these buses travel a slow route - Aguinaldo Highway, which traverses Bacoor, Imus, Dasmarinas, and Silang in Cavite.
Batman Star Express
Golden Dragon (terminal – behind Sogo Hotel and McDonalds near MRT Taft Avenue)
Kirby, Mindanao Express
Lorna Buses (starting point Lawton, passing Taft Avenue, turning right at Quirino, and left to Roxas in Manila, proceeding to Coastal Road and Emilio Aguinaldo Highway.)
Kindly ask the bus conductor to let you off in Tagaytay Rotonda.
There are buses going to Nasugbo in Batangas parked in front of Alimall, Cubao. There are Air-conditioned buses available. I still don't know the fare as of this writing because we usually bring our own car whenever we visit Tagaytay City.
You could also try the bus terminal at Taft station. If you are coming from MRT, take the exit at the left side. You will find Crow buses going to Olivarez/ Nasugbu at the back of Dunkin Donuts/ Chowking/ Sogo. It will pass Tagaytay City.
Travel time is approximately 3 hours. So that's a pretty long ride if you avail of public transportation.
Option #2 By Van
There are vans going to Tagaytay in Mandaluyong just in front of Jollibee in Starmall, Mandaluyong.
You could also ride a van located along a street before Metropoint mall along Edsa-Pasay Rotonda. The van is going to Batangas but it will pass by Tagaytay City via Sta. Rosa exit. This will shorten your travel time to just about 1 hour and a half. The route is through Southwoods exit then to Aguinaldo highway, Silang, Cavite.
Option #3 By private vehicle
By private vehicle from Metro Manila:
Go to the South Luzon Expressway (SLEX) from any of the following points:
Buendia Flyover (Gil Puyat Flyover) Skyway: Gil Puyat Ramp Skyway: Makati Arnaiz Avenue / Pasay Road Intersection Skyway: Don Bosco Magallanes Skyway Entrance: Magallanes Nichols Toll Barrier C5 Merville Skyway: Bicutan Bicutan Skyway: Dr. A. Santos (Sucat) Sucat Skyway: Alabang South Station Alabang Filinvest Susana Heights
Note: If you choose to take the Skyway after the toll plaza, get off the ramp leading to the rest of SLEX below. Otherwise you will end up in Alabang-Zapote.
Leave SLEX at the Greenfield City/ Eton City Exit (Malitlit Exit).
Drive along the Greenfield Parkway, passing Eton City on the right and Pramana on the left.
Three kilometres from SLEX you will arrive at a fork in the road.
Take the left road which is United Blvd.
Drive straight ahead for the next four kilometers.
At the intersection just past the Southern Luzon Hospital, drive straight ahead.
Turn right at San Bruno Drive passing Paseo de Sta Rosa.
Drive straight ahead until you reach the Tagaytay-Sta.Rosa Road where you turn left across from Rose and Grace Restaurant.
Drive along the Tagaytay-Sta. Rosa Road for the next seven kilometers passing Sta. Elena Subdivision, Brittany, Nuvali, and Crown Asia.
Continue until the two-lane road passing through Silang, Cavite. Landmarks are Pasong Langka, Ponderosa, and Windsor Heights.
Follow this road until you arrive at the Tagaytay Public Market just several meters from the Tagaytay-Calamba Road.
Turn left here -- you will be heading in the direction of the Picnic Grove. (Meanwhile, enjoy breathtaking views of Taal Lake and Taal Volcano on your right).
Turn left again on Kaykulot, a single lane road just past the entrance to the Picnic Grove. The Tagaytay Retreat and Training Center is 800 meters from this point
Travel time: About 1 1/2 hours from Manila Toll fee: I still have to recheck before posting it here.
