Following its announcement that all of the 7 million rental listings on its platform will be verified over the next year, Airbnb has announced new guidelines for its Experiences programme, including more screening for risky experiences.

All will be “100 percent verified”, and hosts of technically specialised experiences will need to provide proof of permits, certifications and licenses, including activities such as helicopter flights and whitewater rafting, outdoor activities near bodies of water, high-altitude hikes, and backcountry skiing.

They’ll also need permits required for experiences on National Park and US Forest Service lands, complying with rules that they should already be following. “High-risk” activities such as skydiving, bungee jumping and ice climbing are already banned from Experiences.
