Most people dream of having a pool in their backyard for those hot summer days. Talking about pools, this is the ultimate backyard pool. The incredible pool shown in the video below features five colossal waterfalls, a 300-foot lazy river and a tunnel deep enough for scuba diving. It’s like having your own water park, but it doesn’t come cheap. The 140-foot long and 60-foot wide pool costs more than a car. In fact, it costs more than a house, $ 2million, to be exact. This definitely goes on my wish list for when I become a millionaire.
