St Kilda Boat Ramp is part of the extensive St Kilda Marina complex.
As far as boat ramps go it can vary in terms of quality.
Fundamentally this is a good ramp.
However, a lack of ramp maintenance in the past, at times, means it’s not unheard of for algae to make the ramp so slippery that vehicles have on occasion slid right on into the water. Not such an issue for 4WD’s.
