The easiest way to go to Tagaytay is via FX for Php180 from Starmall, Shaw Blvd. Just ask the driver to drop you off in Rotonda, there's a lot of tricycles and jeepneys there. Starmall is In front of SM Megamall. It would just take about 1 1/2 - 2 hours. You can also ride a bus (San Agustin bus) for a cheaper price of Php 104 from Cubao but it would take you at about 3 hours travel time.
Picnic Grove in Tagaytay is ideal for family, couples and friends or even solo travelers who just want to unwind and breathe in fresh air away from city's pollution. It is a themed park and you can do a lot of activities in a day. You can try horse back riding for only Php 200/hour, Fish Spa Php199/30mins, Zipline and cable car for Php200 each/one way, Php300/two way and an additional of Php100 if it is a holiday and with free souvenir photo. You can also visit the jungle adventure in which you can take pictures with a crocodile or snake for Php150 and see the butterfly garden for Php 50. Also, you can do kite flying, you'll just need to purchase a kite. Lastly, it would not be complete if you will not try their specialty Bulalo, there's a lot of restaurants that offers it, inside the park is the Alamat Restaurant but we try at Koorah-Koorah restaurant located outside and in front of the park, well, the food is ok, taste good, serving is big but the service is too slow... Not advisable if you are starving to death. ^^,
There's a lot of souvenir shops inside the park, prices are fixed especially t-shirt but you can buy it cheaper outside the park. ;)
