The Taal Volcano at Tagaytay is often described as "an island within a lake within an island within a lake" because of its rather interesting geological formation.
Taal Volcano is located about 60 km (about 37 miles) south of Metro Manila. Last major eruption was reported back in 1965 that affected villages in the surrounding area.
Smallest volcano in the world It's active! Has a lake in the crater and is also surrounded by a lake
For nature trip, this one is a must see. With relaxing view of Taal lake and volcano.
Can't escape this when you go to Tagaytay. Even if it's just to admire the natural volcanic formations, or to actually take a boat ride and do the available hike, it's a must-see/do.
