With the continuous expansion of Metro Manila, the city is now part of Manila's conurbation which reaches Lipa in its southernmost part. The city shares its borders with Calamba, Laguna, to the north, Tagaytay, Cavite, to the northwest, Talisay to the west, Santo Tomas City to the east, and the towns of Balete and Malvar to the south. It borders on Taal Lake to the west. The town is known for the Old Tanauan Church Ruins, the most important archaeological site in the municipality where human remains from the colonial era have been unearthed.
