I think it's like 5ft over Summer Pool (680 ) before it's at the top of the ramp where it meets the turnaround ... so you'd still have to climb on the trailer tongue and onto your vehicle if you're by yourself.
OH, and one other thing ... Holmes Bend launch fee is still $5.00 and will be charged starting April 1st. HOWEVER ... there will be no cash payment !! There will be a new box that accepts credit cards only !!
