Iceland: Seljalandsfoss Waterfall (Revisited)
Seljalandsfoss waterfall is not the most famous or largest waterfall in Iceland, but definitely the most beautiful. It drops 200 feet over a cliff into a pool, and you can walk all around it, including behind. You do get absolutely soaked, which is a small price to pay for seeing rainbows through the wall of falling water (if you get lucky with the sun in Iceland). The entire cliff was the former shoreline, before the lava flows extended it by several miles. There are dozens and dozens of similar waterfalls dropping everywhere as far as the eye can see.
