What Travellers Say
Reviews Summary
Visitors find the Round Lock of Agde to be a unique and interesting engineering feat, particularly appreciating the three-way junction and the helpful lock keepers.

It's considered a worthwhile stop for its historical and functional significance.
"Navigation into the lock is fine, the lock keeper very helpful and friendly. It’s a bit confusing at first where to tie up once inside the round lock. It only went down a little, then quickly we were out again. We arrived midday. 14.15"

"The last lock on the Canal du Midi before it reaches the Herault and thus the sea (though there is another stretch toward Sete from the Herault), this is unique on the canal in being a three-way lock with room for boats to turn round. Originally built fully circular, then later extended to allow larger craft to navigate it, boats entering from the west have a choice of two exits to the Herault. The lock-keepers are quite animated, and it's fun to watch boats getting through. It's very close to the railway station, and an easy walk or cycle into old Agde."
