Well, I'm assuming that they are dragons. They could be nagas. But this is the eaves of the roofs of Lingyin Temple in Hangzhou, China, so I'm going to go with (albeit skinny, serpentine style) dragons.
The Swiss are mountain goats. My apologies. Their hiking trails are graded by difficulty, and an "easy" Swiss hike is a "hard" American hike. The signposts along the trail, telling you which way to go, are color-coded with the difficulty info so you can presumably make reasonable choices.
