Has a lot of nice walks. The directions are pretty good and you can even navigate by opening up the page with the map for the walk on your phone and enabling gps so it shows you exactly where you are in relation to the route.
Before I get horrendously villified, I should point out that relying completely on your phone is a bad idea in case you get out of signal, water gets into it or battery runs out.
The Trotternish Ridge is a definitely an option, though at 22 miles or so you probably only want to do a section of it. There is a bus service that goes from Portree, round the Trotternish and back into Portree, so you can use that if you want to do a point-to-point walk and get back to your car.
Blabheinn is probably the easiest munroe on Skye but it's still not excessively straightforward if the clag comes down.
I run a glamping site so let me know if you are looking for accommodation.
