When we arrived and while we were taking a break we saw a lot of people coming and going. We thought that was odd since we had only encountered three people on the whole way up. What's more, none of them seemed to be working up a sweat.

The solution to this little puzzle was this sign at the top of the mountain. Apparently, for lazy people, the peak is also reachable by way of a 500 meter walk from the parking lot!
