It is not a beginners trip – the long loch sections can be windy, remote and unforgiving. It is however wonderful, challenging, scenic and a great way to travel. It is also increasingly busy.
Camping: you are not meant to camp on the canal side and busy sections – imagine having campers on your street each week, peeing, pooing, drinking too much, leaving litter each week – unacceptable, and hence the restrictions due to the few idiots. However, use some common sense, hide as best you can and leave nothing behind and you can still wild camp as needed.
If you are not sure, head off with a guide. No, please do – they are soooo worth the money. Beyond Adventure have a huuuge Lavvu with woodburning stove you can all gather round at the end of a long day!

If you are paying a guide, there are nicer trips! River Spey, Tay and Royal Dee are ace, lochs wise Shiel is a stunning place as is Awe.
