Ben Nevis is the highest munro but this in itself means that its more popular and has certainly had damage/erosion from all the walkers that are on it every year. Because of its height, the weater is at best unpredicatable and there are regular issues with people becoming lost, injured or worse.
The Mamore range is ideal for those that wish to do more than one munro and includes the Ring of Steall which is a great hike covering four munros although it is said that it is not as challenging as going up Ben Nevis. almost 8 years ago
I have no experience of Mamore however I have walked up Ben Nevis and the main walking route is highly acccessible. To my recollection the start of the walk isn't far off the road & over a tiny bridge so getting to it is very easy. There's a fairly clearly defined path, weather dependent, even so high up on the mountain I nearly took the wrong route down so it can be confusing. Go prepared with proper clothing, drink & food supplies and a compass. and tell someone you're going & what time to expect you back. I was lucky, I got good weather however not everyone does. The weather on this mountain is unpredictable due to its height. Try to start your climb as soon after daybreak as possible if the weather is good, i.e. whatever you do don't get caught on the mountain after dark. almost 8 years ago
