Not quite 500 feet from shore, the relatively flat and shallow bottom of Incline Beach gives way to a sandy trench that drops hundreds of feet down at a sharp angle. As you get deeper, the sand forms mogul-like shelves covered in pine needles, the occasional rock and giant log, and—starting at around 120’—a shocking number of golf balls. Seriously, if you’re a golfer, just bring a bag with you, and you’ll never need to buy balls again. There’s also what could be what’s left of a sunken speedboat (no idea, see below). Because the bottom composition doesn’t change much as you descend in the trench, getting deep here is deceptively easy, so keep an eye on your gauges.
There’s a dock on the northwest end of the beach that basically points to the northwestern boundary of the trench. You’ll find the beginning of the trench due south of the end of the dock about 400 feet. It’s pretty well straight out from the orange buoy. The trench is obvious on both the depth chart and Google map below (zoom out a little).
Dive flags are required here. Parking is free. The area is open year round and has facilities all year, too, even if it’s just porta potties in winter.
