* Sea-inlet lochs are often called sea lochs.
So...they are the same! All I remember is driving through the Highlands and being breathtaken by the beauty and my boyfriend at the time telling me that the lochs were 1,800 ft. deep! I remember thinking that they looked like you could jump in and have a good time, but he told me that “your feet would have to sink nearly half a mile to make it to the bottom” Besides Nessie, :-), is there life in dem der lochs?
