Many towns and cities are problematic for mooring, not least because local dog owners see the towpath as a useful facility. In Northampton not long ago, a moored narrow boat was set alight by local youths. Though it's more common for that to happen to long- term moored boats that attract dossers.

Besides which, the townscape is often simply miserable. You do get some interesting industrial hsitory, but sheer dereliction is all to prevalent. I prefer the rural routes. And Mo is right, even disregarding folk clubs, the Shroppy is wonderful. So is the Caldon, the Kennet and Avon, the Llangollen is rather crowded especially in holiday time, I've not been on the Leeds and Liverpool but I'm told the Yorkshire side is better. And many other routes.

If you want to go up the Macclesfield, take your own water. Wherever you go, take plenty of supplies, as convenient shops are becoming a very rare resource in many rural areas.

Don't attempt any of the "rings" for a first hire. I've heard too many horror stories of people miscalculating the time required and having to do late nights and early mornings to make it on time.

A lot will depend on the size and enthusiasm of the crew. You wouldn't want to do Tardebigge, Hatton or Caen Hill flights (31, 21 and 29 locks) if it's just you, the wife and a 6 year old.

Semi-trad or cruiser for the stern, with a trad stern the steerer is rather isolated. You'll find most hire boats are cruiser. Avoid Canaltime hires (if they still do them), apart from their reputation (or rather that of their hirers) the boats don't allow access from the cabin to the bows, which is the best place to sit if you aren't steering.

You'll get a lot of useful advice if you ask the same question on uk.rec.waterways.
