During the week, there are not many visitors here, and because the beach is so big, it is almost always possible to find a nice private spot.
If you are arriving from Cruz Bay via Centerline Road, turn left at the
Colombo Yogurt stand. Go down the hill and turn right at the first intersection.
This will take you to the Leinster Bay shoreline where you will turn left
and proceed to either the parking area by the stone building and take
the walking trail or directly to the parking area by the beach.
The Francis Bay Trail runs along the salt pond behind the beach and is an excellent place for bird watching, especially early in the morning.
Francis Bay Pond Overlook
Millions of fry frequent the shallow fringing reef along Francis Bay's rocky north shore. These small silvery fish travel in close proximity to one another in large schools that look like underwater clouds.
On the outskirts of these living clouds, in slightly deeper water, lurk predators, such as jacks, yellowtail snapper, Spanish mackerel, barracuda as well as some respectfully-sized tarpon and pompano. Every now and then, one of these larger fish will attack, moving quickly into the glittery mass. The fry are extremely sensitive to minute changes in water currents and can sense the approach of the hunters. In a burst of speed they move away from the oncoming predators. Some are successful and some are eaten. Some breach the surface of the water, fly through the air and splash back into the sea. This splash, however, puts them into yet more danger. Waiting pelicans, gulls and brown boobies swoop down in the vicinity of the splash scooping up their unsuspecting prey.
In the midst of all this activity, large schools of French grunts, oblivious to the drama around them, hover, almost motionless, over and around colorful live coral. Parrotfish and blue tang swim about, grazing on algae. Little damselfish defend their self-proclaimed territories by darting menacingly at intruders that are often much larger than them.
A closer look will reveal all sorts of beautiful and mysterious sea creatures like small eels, feather duster and Christmas tree worms, brightly colored sponges and gracefully swaying gorgonians like the colorful sea fan.
In the underwater grasslands just seaward of the reef, snorkelers may be fortunate enough to see large green sea turtles often accompanied by bar jacks that follow along just inches above the turtle's back. In this area, one may also see southern stingrays, conch and trunkfish.
Novices who feel more comfortable close to shore can have a rewarding
snorkel around the rocks on the south side of the bay between Francis
and Little Maho or over the seagrass that lies in shallow water on the
other end of the beach.
