The Dundas Castle is owned by the Prince Hall Masons.
There are alligators in the surrounding area but not in the natural day-use pool. Though, many people visit each year and there have not been any major problems.
These steps were suggested on the best way to go about getting a chance to explore North Brother Island!
1) Contact the parks department. They don’t even let themselves visit the island most of the time. March to October is off limits. That’s when the herons nest.
2) If the parks department gives you permission, you have to charter a boat, which can be really expensive. To make it more affordable, find other folks who need to visit and split the cost with them.
3) Thing is, a big group requires a big boat and a big boat can’t dock on the island. There’s no dock. We had to tie off on a rotting piling, motor over in a smaller boat, three by three, and beach ourselves onto the sand. In short, to get to North Brother Island, you have to mildly shipwreck yourself.
