The EpicLava tour in Hawaii allows visitors to get up close and personal with active lava flows. Each tour lasts around six hours and those wanting to take part - under the careful watch of guides - are allowed to get as close as physically possible under the extreme heat. The tours, which start at $165 per adult, first ran in 2014 and guides use webcams to check daily and see where the best lava is flowing. The team take groups out early morning, asking those who want to take part to meet at 4am before setting off across Hawaii Volcanoes National Park on the Big Island. They then hike between five to ten miles after being provided with all the gear needed to stay safe.
