I guess we can all look at the same thing and see it differently.
Karakter is within the twenty minute parameter you set but it’s not a walk I would want to do in the dark, and particularly after having a few drinks. There is no boardwalk or sidewalk and the only lighting is from the beachfront properties along the way. If you plan on doing this, make sure you bring a strong flashlight and do the walk during the day the first time.
