Ullapool is a great base if you are keen photographer. The north west highlands offer great rugged landscapes, amazing sea scapes and during winter months a very deep sky with a good chance of viewing the northern lights.
Ullapool itself is such a picturesque village and you don't have to travel far if your looking for great scenery. A short walk up Ullapool hill will give you great views overlooking the village and both west over the Summer Isles and south down Loch Broom.
If you want to travel further a field you have Assynt and North West Geopark in the north which offers dramatic mountain ranges, lochs and simply stunning deep dark skies with very little light polution.
