19-Feb-2008 -- Visiting St. Lucia during an 11-day cruise with RCCL, my son Fredrik & I decided to put on our running shoes and go for a training run, making sure that we would pass this confluence on the way.
It is located almost on top of one of the hills that surrounds the cruise harbor city Castries, we got very warm trying to run/jog up hills that seemed to be nearly as steep as the bottom of a ski jumping hill. After passing through a road tunnel (with a narrow pavement on the side), we took a road going straight up, until it ended about 300 m from the confluence.
At this point we found a narrow path going further uphill, passing through an area with what we assume must be unregistered/unofficial housing: The houses were mostly built out of cinderblocks, dug into the hill on the upside and supported by long wooden poles on the downside.
We got stuck in this area until until a nice lady came out and told us that we had to pass through her lot, past a gate and then get onto a larger path. With her help we ended up just below the confluence point, crossing a regular street to get into a small park/memorial area with the foundations of the artillery battery described by the third visitors.
We have visited this confluence on a previous cruise, taking a taxi up the hilly roads, and approaching the point from above. At that time there were several large trees surrounding the confluence, and hard to get a good GPS fix.
Now there were people working on the big villa, work which had been started by the time of the third visit almost two years ago, and the trees had been removed, making it possible to get all the zeros while having very good gps reception, including one of the US WAAS satellites.
It is however very likely that when the villa is finished, the confluence point will end up behind a fence, requiring a permit from the owners to get any closer than the 15-20 m allowed by the park below.
