Thrill seekers are addicted to visiting places around the world that can give them that adrenaline rush they look for. But even the most intrepid of them would think twice before experiencing some of the most beautiful, yet dangerous, pools or waterfalls. Here are the five most hazardous places to take a dive in.

1. Victoria Falls, Zambia

Lying perilously close to a 100-foot drop, it looks like an infinity pool, yet it is far more dangerous. You might get quite an adrenaline rush bathing right beside the ridge of the waterfall, but you’ll want to take extreme caution doing so.

2. Samaesan Hole, Thailand

Located in Thailand’s Samaesan Bay, the Samaesan Hole reaches depths of almost 300 feet. While it is a popular spot for experienced divers, many have run into trouble there. A former military munitions dump, there is believed to be unexploded ordinance in among the depths.

3. The Strid, England

The picturesque Bolton Strid looks like an idyllic rural brook, typical of the bucolic English county of Yorkshire. In reality, the Strid, though very narrow, reaches unknown depths, and it has extremely strong undercurrents that have claim the lives of some unfortunate enough to fall in.

4. Hanakapiai Beach, Hawaii

The stunningly beautiful Hanakapiai Beach of Kauai Na stretches for two miles along the popular Kalalau Hiking Trail. High surfs, very strong rip currents and high tides make it extremely hazardous. Additionally, the beach is very remote and has claimed the lives of dozens of people over the years.

5. Boiling Lake, Dominica

The name says it all. With a water temperature reaching an average of 200 degrees Fahrenheit at the edges of the lake, Dominica’s Boiling Lake is certainly not a place where you’d want to lose your footing.
