This looks like an amusement park ride, but really it's just an exciting kayak trip into a tunnel. The dark ride through the drainage pipe seems to go on forever, but finally, we can see the light leading back to the river.

Apparently, rooftop kayaking is a sport too. With a pillow for an airbag, YouTuber Shredwin climbed into a kayak set to be launched off the roof. Luckily, the landing spot was a trampoline ball pit.

For something more peaceful, this guy went kiting underneath the Golden Gate Bridge in San Francisco, California. We're used to seeing the bridge from a distance, so this kiter's view is incredible.
