On Skye go and see the fairy pools although parking can be an issue due to limited car parking space. Old man of Stoor and kilt rock are other places to visit.
A bit further afield and maybe too far for your timescale is the Bealach na Ba road to Applecross which is a single track and steep road with stunning views if the weather plays nice.
Buy some Smidge incase the midges are out in force as they can spoil a holiday if the weather is in their favour.
We did the gondola ride 2 years ago. I shat myself hate heights and my mrs and lad are sat there swinging the thing, I think I almost cried!!!
It was a good thing to do though apart from that, it gets very busy and would check before traveling too far make sure its open we did an hour n half trip to find it shut the first day we went but rang them up at 8am the following day to check.
The day it was shut we ended up driving to the white beaches Traigh Beach I think it was called stunning place.
Cheers guys, I sh*t myself climbing up a step ladder so I'll have to be brave to go up there but if it's worth it I'll have to just hold my balls and get on with it
