Curious giraffe stops couple in their tracks and begins nuzzling them in incredible close encounter

I had just moved to South Africa from America and my girlfriend took me mountain biking at a safari called 'Lion and Safari Park'. We were two hours into the ride when we spotted a herd of seven giraffes. The one featured in the video stood in the road for about an hour and we finally decided to creep around her. I had my 360 camera over my shoulder as I approached and she decided to come over to sniff my helmet. I was looking down the whole time as I was in shock from her size and could feel her breath. She was so gentle and gave us a moment I'll never forget.
