When you arrive at Loch Ness, you must take a boat trip.
We booked a boat from a local company, which has multiple boarding and disembarking points. So in order to avoid walking back to the road, we chose to go down to the castle.
The weather was good on the lake, and it was very pleasant to look at the lake view and the mountains on both sides. Of course, the lake monster cannot be found. The BBC organized people and spent two or three years blocking both ends, but they still couldn't find it.
The facilities on the boat are quite complete, and there is Costa coffee.
