Take a dip/swim at the Mount Pinatubo crater lake? Check.
See the other side of the 2-km wide crater lake? Er. How?
Ah, this one's easy - take one of the three boats available at the lake. Each boat can accommodate up to six clients plus two boat men rowing the water vessel to the other side. All passengers are required to wear a life jacket. The sun can be pretty strong and the water reflects UVA and UVB rays, so make sure to slather your sunscreen on. Bring enough water to avoid dehydration as there is no shelter on the opposite end.
