A popular travel blogger has been confirmed as one of three people killed after an accident at a waterfall in British Columbia.

Ryker Gamble had a following on Instagram and was the co-creator of the popular YouTube adventure travel channel High On Life.

The Vancouver Courier reported Mr Gamble's fellow YouTuber Alexey Lyakh and Mr Lyakh's girlfriend Megan Scraper were the two other people killed at Shannon Falls.

It said there were reports the high profile bloggers died trying to save Scraper, who slipped and fell into one of the pools.

It reported a fourth friend witnessed the incident and ran down the mountain to call for help.

Corporal Sascha Banks of Canada's federal police service said the victims were in their 20s and 30s and were swimming in a pool system at the top of the falls "and then walking along the ledge shortly thereafter". They fell nearly 30 metres.

A family member of Mr Gamble confirmed his death to The Associated Press.

The Shannon Falls is the third-tallest waterfall in British Columbia and police were forced to call in search and rescue teams and helicopter units in order to recover the bodies, as the "extremely difficult" and "very dangerous" terrain combined with a heavy water flow made for a risky recovery effort.

Mr Gamble's girlfriend Alissa Hansen posted an emotional tribute to Instagram.

Grief seems to bring everything to a halt. What was once possible seems irrelevant. The schedule is cleared, the mundane ignored. One moment a wave of catastrophic emotions, the next a cavern of emptiness. Death is not a request to stop living, it is a request for loving. It calls us to see fully what is in front of us. To see what needs healing. To see those for whom our hearts would break if we did not speak the words that need speaking. It asks us to tend to one another. To value this moment here and now. To face our own ephemerality. Death violently shakes us awake, time and time again. Words by @heyheatherobscura. The only words I have right now to share are from my dear soul sister Heather. May we all send prayers to their souls as they transition.

A GoFundMe page has been set up to support Ms Hansen.

High On Life had almost 500,000 subscribers and the team's last video, about the best things to do in Bali, was uploaded just four days ago.

In 2016, the group was forced to apologise after walking into restricted areas in Yellowstone National Park around the Grand Prismatic Spring.

In the apology on Facebook, they said they had made a $5000 donation to the park and they had made a mistake that "doesn't reflect our respect for the environment".
