Option 1: via SLEX Sta. Rosa Exit, the most popular and easiest, is a straight drive all the way to Tagaytay City Public Market where you turn right going to Tagaytay city proper and Mendez, amadeo, ALfonso,Nasugbu/Balayan/Lemery Batangas or left going to People's Park in the Sky, Development Academy of the Philippines, Picnic grove, Tagaytay Highlands.Usual travel time from Makati CBD is 1.5 hours depends on the traffic situation
Option 2: SLEX Greenfields Exit, an alternate route to Tagaytay that pass by Pramana, Nuvali, Eton City and Paseo de Sta. Rosa, ideal to avoid traffic buildup on Sta. Rosa-Tagaytay National Road on Saturday mornings thus making it the fastest route to Tagaytay on weekends.

Option 4: Roxas Boulevard, Baclaran, Coastal Road, Bacoor, Imus, Dasmarinas via Aguinaldo Highway. Not recommended due to presence of heavy traffic made worse by SM Dasmarinas and Robinsons Palapala. At the end of Aguinaldo Highway is the Tagaytay Rotonda (roundabout) where a statue of Ninoy Aquino, a BPI with ATM, Days Inn, Max's Restaurant and 7-11 store as landmarks.
Option 5: Another route for the adventurous to Tagaytay is via Daang Hari that passes by Molino, Bacoor, Imus, Dasmarinas and Silang. It bypasses the traffic chokepoint of Bacoor rotonda but not SM Dasma and Robinsons.
Option 6: From Sto. Tomas, Batangas via StarToll in going to Lipa City, take Sambat exit and follow the national road to Talisay then go up Ligaya Drive, the zigzag road to Tagaytay (sometimes called Bitukang Manok, not for the faint of heart and newbie drivers)
