If you’re into outdoors stuff, then a walk up onto The Cuillins ridge is something worth doing. The Cuillins are the most extreme mountainous like mountains in the UK, most others being just big hills. Depending on your ability, chose an appropriate route to one of the summits, the views of the ridge and surrounding area will be worth it. Some of the summits require climbing skills, but some are airy walks. Maybe take local advice for appropriate routes to the best vantage points. I’d probably recommend walking up Sgurr Dearg to see the inaccessible Pinnacle (if you’re up to it, the pinnacle can be climbed and absailed), you also get great views of Coire Lagan, the cioch (of Highlander fame) and the ridge in both directions. Obviously, do it on a clear day.
