Taal Volcano is a complex volcano located on the island of Luzon in the Philippines. It is the second most active volcano in the Philippines with 33 historical eruptions. All of these eruptions are concentrated on Volcano Island, an island near the middle of Taal Lake. The lake partially fills Taal Caldera, which was formed by prehistoric eruptions between 140,000 and 5,380 BP. Viewed from Tagaytay Ridge, Taal Volcano and Lake presents one of the most picturesque and attractive views in the Philippines. It is located about 50 kilometers (31 miles) south of the capital of the country, the city of Manila.

The crater lake on Volcano Island is the largest lake on an island in a lake on an island in the world. Moreover, this lake contains Vulcan Point, a small rocky island that projects from the surface of the crater lake, which was the remnant of the old crater floor that is now surrounded by the 2-kilometre (1.2 mi) wide lake, now referred to as the Main Crater Lake. Vulcan Point is often cited as the largest third-order island (island in a lake on an island in a lake on an island) in the world, though this is also claimed to be an unnamed Canadian island located within Victoria Island

Therefore, Taal has an island within a lake, that is on an island within a lake, that is on an island: Vulcan Point Island is within Main Crater Lake, which is on Volcano Island, which is within Taal Lake, which is on the main Philippine Island, Luzon.
