You should have a good level of fitness to do this route with previous scrambling and hillwalking recommended. You will need to have done some rock climbing before, preferably some outside or indoor climbing at around F5+ and above. Please feel free to get in touch to discuss your experience and aspirations.
It is worth noting that this climb is not possible in all conditions and a fairly settled, dry spell of weather is recommended.
A step up from Tower Ridge and North East Buttress, Observatory Ridge is the hardest of the Nevis ridges. It is graded a Very Difficult rock climb and consists of around 3-4 pitches of climbing followed by easier mountaineering ground to the top. This is a truly stunning climb with superb situations as the climb is situated between Zero Gully and Point Five Gully, two of the famous ice climbs in winter. The route tops out very close to the summit of mountain, giving a superb way to climb Ben Nevis, as well as a highly enjoyable 4 star classic climb!
