I don’t really see a problem with going up Nevis without maps etc, so long as you take the tourist route, start early, and the weather is good. In those conditions the tourist path would be busy and it’s just a long hike, there’s no mountaineering involved at all. It’s very long and quite boring tbh (I’ve done it about 20 times now). If you subtract one of those conditions, however, then just having a map isn’t enough. You’ll also need the practiced ability to navigate without visibility. Scottish weather is either perfect, or (much more commonly) capable of drastic changes in 10 minutes.
