Color Key:
- Yellow: the 400m-long trail.

The area in white is open water: Río de la Plata (ie, River Plate), lagoons and neighbouring sailing club
- Area outlined in sky blue is the "lagoon" (sometimes, as here, much invaded by native floating vegetation)
- Area outlined in pink is the main stand of rushes (now partly invaded by exotic Yellow Iris)
- The area between the coast and the first green line are coastal reeds.
- The area between the first and second green line is coastal bushland (now invaded by exotic privet)
- The area behind the second green line is riparian forest, where most of the ceibo trees grow and includes the willow forest.
- The street outside is marked in blue.
Note: The trees that have a reddish tinge are Ceibo trees in full bloom. The larger tres are mostly willows.


"Milestones":
Red arrows mark specific points at which the trail may sometimes be closed to the public. From left to right: 1) the entrance to the reserve, 2) at the lagoon, 3) at the metal bridge, and 4) at the bifurcation about 1/2 way around, forcing the return to be back along the same path. These closures may be required during or after rain (as the trail becomes muddy), peak tidal flooding (causing much of the reserve to be completely covered by water and leaving behind large ammounts of trash, which has then to be collected), or after serious storms that can cause much damage (fallen trees, land shifts, trail "wipeout", huge piles of rubbish such as tree branches, reeds and plastic bottles, and so on). Recovery and cleanup can be slow, but eventually happens! During all 2003-2004 the return leg running next to the yacht club premises was closed as this section has sunk and the trail is always soggy. Plans are under way to build up this section of the trail.
