Bypassing the main trails that are marked is sometimes warned against. This is because of risks with falling or shoving rocks. However, when you only bypass the trail to go to a lake that is off trail, pay attention to the exact spot where you leave the path, because in attempting to getting back to the trail, you could get lost for a while, since it all looks like the same.
It’s a good thing to ask the staff at the hizha whether if they know what the weather will be that day. Since the trails are often very steep and rocky it can be a problem when you are going downwards the hill when it suddenly starts pouring rain, making all the stones slippery. Even when you have mountain shoes you still slip. Better take a easier trail that day then
