It definitely takes longer than the 1.5-2.5 hours they say if you stop to enjoy and of the points of interest. We also had to pay for a map at the building which I thought was odd.
Because of the difficult access it isn't full with people although many decide to trek. Bottle Beach is a beautiful, quiet place where you can relax for the day.
The ramp is nice and big with one dock. However the water is very low and leaving the ramp on water is narrow and 4’ deep on 6/2/21. Be careful and watch for underwater rocks.
