Bear Grylls has said it was a "privilege" to trek through Alaska with US president Barack Obama this week. The pair teamed up to film a special episode of Running Wild with Bear Grylls, and have both shared photos from their adventurous trip.
The president posted a selfie of himself and Bear smiling together on Tuesday evening, joking: "Glad this was the only Bear I met in the park."
The post was soon shared by Bear, who added: "Was such a privilege to adventure with you!"
The explorer also tweeted his own selfie with the president and said they had shared some "special moments" during the trip.
"@POTUS such special moments all through this journey. & what you are doing to help protect our planet is inspiring."
It was announced on Sunday that president Obama would be filming a special edition of the show in Alaska to observe the effect of climate change in the area. Filming coincided with his three-day tour of the state aimed at highlighting the effects of climate change.
During the visit Obama has become the first sitting US president to visit the Alaskan Arctic, and will address foreign ministers from Arctic nations at a conference on climate change.
After the announcement was made, Bear tweeted that it was "an honour" to work with Barack Obama, writing: "Thank you for the call up. An honour. Will do my best to keep the adventure safe but fun! See you on the ground."
President Obama is not the first high profile star Bear has worked with on his popular show; the 41-year-old has put the likes of Zac Efron, Kate Hudson and Michelle Rodriguez through their paces in his Running Wild series, as well as joining Mike Tindall and HELLO! Online blogger Vogue Williams in the jungle for his Mission Survive series earlier in the year.
