My partner and I took the Loch Ness and the Highlands tour from Glasgow over the holiday weekend. We would certainly recommend this tour!
This tour was a small group, with just 12 people. We could sit together, but were scially distanced from other people. We had to wear our masks on the bus and despite the tour being 12 hours long it wasn't too much of a hassle. There were stops every hour or so when we could get off the bus to stretch our legs and get fresh air.
At Loch Ness we could go for a cruise, but due to Covid the castle wasn't open. We got great views from the boat though. If you take this tour I'd recommend buying the boat trip, it's really special.
Our tour guide was terrific! She provided a commentary for most of the tour and despite being Scottish I could understand every word! She gave us a break every so often by playing music which was lovely to sit and watch the views go by.
I would definitely recommend Scottish Tours.
