I am posting a review of a multiday tour--I hope that this subforum is the right place for it.
I had a wonderful time in early June in the Outer Hebrides on the Gentle Rambles tour, which the Hidden Hebrides company grades as "easy." There were five other travelers on the tour with me; I was the only American, while the others were English. The greatest strength of this tour was the excellent guides, Emma and Eilidh. They were both friendly, warm, knowledgeable, and helpful. As we spent the most time with Eilidh, I can say that her connection with the islands and the residents--as a BBC Gallic presenter, she was like a celebrity, everyone recognized her and greeted her warmly--was the selling point for this tour.
The grade level of this tour was a good fit for me, an inexperienced walker. I felt challenged but supported. I am unused to walking on informal/unpaved paths, but the 1-2 hour duration of each outing was perfect for me. There was a good variety of terrains and outlooks. My favorite parts were the Vatersay beaches, which are incredibly beautiful and so clean. I would love to revisit this area.
Our accommodations in Stornoway (Hebridean Guest House) and Benbecula (Borve Guest House) were very good. The food we had was great, too. I would highly recommend this tour to anyone who wants an easy/accessible walking tour of this lovely part of Scotland.
