In reply to woppo:
depends what you want, it's less then an hour drive.
between bruges and dudzele, you can take a detour through the fields, on the righthandside of the bouwdewijn canal, then through dudzele and follow the path immediately next to the left hand side of the canal into zeebrugge. Or choose the right side, off road, difficult and bit dangerous.
you can also follow damse vaart from brugge to cafe 'siphon' (= crossing of 3 canals) and then follow the two other canals direction zeebrugge.
edit: apparently explained it the other way around, but it remains the same
strange to see someone asking questions about my home. PM me if you want more info
