There are usually some very good views of the mountains on Mallorca as you approach the island.Trouble is knowing which approach which will be used as this will be based on the surface wind.If they are on southwesterlies then sitting on the right usually means flying over Pollensa with the highest mountains on your right.If on easterlies sitting on the left is best.
Good idea to check out FR24 as suggested.Pilots are usually too busy to point out scenery near destination.Duff info is normally only when ATC change things.
