The "Bubali Bird Sanctuary" has a website as well with a detailed description how to get there as well as photos:
Bubali Bird Sanctuary
One of our favorite birding areas, and one of the easiest to find.
Description: A very large wetland originally supplied with treated water from the island's sewage treatment facility. A canal now connects the area to the sea.
How to Get There: To reach Bubali from Orenjestad, follow L.G. Smith Boulevard west, then curving north for 2.3 miles until you reach an intersection. Turn left (west) towards the beach and follow this unnamed road for 0.3 mile where you will see the entrance to a dirt road on your right about 20 yards from the intersection with J. E. Irausquin Boulevard. This will take you into the thorn-scrub habitat bordering on the mangroves along the west side of Bubali. You can park here to explore the area on foot.
To reach the tower on the north side of Bubali, take J. E. Irausquin Boulevard heading north and travel 1 mile to the rather busy intersection near the Wyndham Beach Resort. Turn right (east) heading towards the big, red windmill and watch for the entrance to a small dirt road on your right within 200 yards. This is the road to the observation tower, which itself should be visible a few hundred yards farther along.
Birding Bubali: On the north side of the site, across from the big, red Dutch Windmill (a local landmark) is an observation tower that affords excellent views of this expansive wetland. From there you can see Pied-billed Grebe, Least Grebe,
Neotropic Cormorant, Caribbean Coot, Common Moorhen, Purple Gallinule,
White-cheeked Pintail, Blue-winged Teal, Groove-billed Ani, various herons and egrets.
