Adventurer Bear Grylls was around the austere mountains of Loch Morar recently and you can see it televised on STV this Tuesday (29th) at 9pm. There will be a mention of the Loch Morar Monster, but how much I am not sure. Loch Morar is much more of a wilderness compared to Loch Ness, a good backdrop to a good monster story.

POSTSCRIPT
Quite a good programme. Bear Grylls opened by paramotoring over Loch Morar. Though there was a chat with one witness and his photo, the main item of interest was the sediment analysis taken at the lowest depth at over 1000 feet with a core sampler attached to a very long rope.
No saltwater from the post ice age inundation was found at the bottom but another water analysis suggested this was a low nutrient lake. A sonar sweep suggested a low fish population. I found this a bit surprising considering the loch is not as opaque as Loch Ness which ought to help the food chain.
