Do yourself a favour and go enjoy this beautiful view.
Unfortunately no parking is available within close range of this cache, so the best will be to park at the given coordinates and to then walk a couple of metres.
The wooden bridge used to open up for boats with long heels to pass through, but this was stopped with the sealing of the locking system which provided throughfare to the ocean.
The bridge was stabilised a couple of years ago and the surface was tarred. It is accessible to the public as it is situated outside of the residential area of the Marina Martinique.
