We visited Scotland in June and we spent 3 nights at the Sunny Brae. We loved the Sunny Brae. There were 4 of us, and we all agreed the Sunny Brae is our favorite accommodation, and we liked all of our accommodations. As jaimeelsabio says, the owners are fantastic!
Restaurants we dined at in Nairn:
The Bandstand - one of our best meals in Scotland
The Sun Dancer - another favorite restaurant located on the beach
Aurora Restaurant - an Italian restaurant; we were disappointed in the food; I would not recommend.
All 3 restaurants are within walking distance of Sunny Brae
The Sunny Brae owners had also recommended One One Two on the Brae and The Classroom; I wish we had gone to one of these instead of Aurora. I recommend making advance reservations for all the restaurants.
Sightseeing:
Cawdor Castle - We visited the Castle and the gardens. Loved the interior of the castle. We did not think the rooms looked worn at all. In fact, we thought they were very elegant with beautiful furniture, tapestries, and paintings. There are several gardens, as well, and they are all beautiful.
Culloden Battlefield - Very interesting to walk through the battlefield; filled with heather and yellow witches broom. I recommend taking a guided tour from the Visitors Center and visiting the museum. We didn't do this because our friends weren't interested but I do regret it. I think we would have understood more if we took one of their tours.
Elgin Cathedral ruins - one of the highlights of our trip. It's about 30 minutes from Nairn
Biblical gardens across the street from Elgin Cathedral.
Whisky tasting at Glen Moray Distillery - tours were sold out so if you want a tour, you need to book in advance.
Also walked along the beach across the street from Sunny Brae.
