I worked in Ullapool a few years ago, and its a great place to be in - certainly in the summer. Its a very pituresque village, set along the harbour. Theres lovely trips out to the Summer Isles , and smaller trips closer by, with a chance to see great sea life. Its busy, the pubs can be jumping - theres often Klyondyers in the bay, with the crew mixing in the pubs and lots of hill walkers. The Ceilidh Place is renowned for its support of music - local and visiting artistes. It has lovely bedrooms and for the less well off ,a bunk house. Theres a well stocked book shop and a good restuarant especially if your vegetarian - where you won't find much of a selection in many places in the Highlands. There are many other hotels and guest houses, a fish and chip shop, a leather shop, a good music shop and plenty nick nack shops. Ullapool also hosts Feis Rois which is a week long festival for children celebrating traditional music - with concerts and plenty sessions in the pubs.
In the winter I believe Ullapool is a completely different place, and it must be strange going from a season of heaving pubs to a few people propping up the bar - but strangely peaceful I'd imagine.
