Check out YT. There are some excellent videos showing the beautiful mountain scenery. I went about 15 years ago, spent 10 days in November riding around the island. Can highly recommend it. Only dilemma is whether to take your own bike or hire one there which saves all the hassle of dismantling yours, boxing it up and reassembly, twice. When there I would focus on the out of town sites rather than the towns/cities. The mountain landscape is just breathtaking. .
