> What's the chances of doing Ben Alder in a day if I cycle to Culra from Dalwhinnie? What is it like to cycle out to it?
I did both in a day. Agree with the extending the day comment (if you have time)
As mentioned, it can get a bid boggy approaching Culra, and if so, abandon the bikes, and hoof it from there.
Talking about 'hoofs', if you see the horses standing around the Bothy, it means there is bad weather coming, and chances are if you ignore it, you will get caught in it on the way up (we did)
If we had just read the signs & sheltered in the bothy for half an hour we would have had a much better experience !)
