The first floating market of the year for the Kennet and Avon Canal kicks off this Saturday, on Darlington Wharf in Bath. It's the first time it's been held here, and the location is terrific. Apart from the traders on their boats there will be stalls and craft demonstrations by other folk from the floating community. And music too!
If you don't know the area, Darlington Wharf is on the eastern edge of the city, close to where the A36 ascends on its way to Salisbury.
If you're arriving by train, either cross the river and turn left, carry on till you meet the canal then follow it up through the lock flight (which is a fine walk if you don't know it) or go to the Holbourne Museum, then up through Sydney Gardens and through the little gate onto the towpath, then left through the tunnel and so to the wharf. This is also a jolly good walk.
If you're driving and want to avoid the horribly expensive parking in Bath, then you'll probably find somewhere along the A37, or drop down to Bathampton and then walk from there along the canal, about a mile.
