Kilauea

It’s never pretty around volcanoes; you don’t need us to tell you that. But we’re going to tell you anyway. Kilauea is an active shield volcano on the Big Island of Hawai’i. It’s beautiful there, we won’t dispute that, but it’s equally dangerous, as volcanoes are generally.

But the part we want to warn you about is the volcanic black-sand beaches, whose temperature levels could reach unreal heights. If the volcano erupts suddenly, which often happens, you would be subject to hot waters or even high tides. While you can still swim there, it’s pretty risky. So dive in with caution!
