"Yes, it takes about an hour."
I would have to say that you would have to be walking at a good
pace to do this in 1 hour, as I had done this walk yesterday
(2/6/11) with 3 children + plus the dreaded pushchair which half
way down was a mission!
We walked all the way there and back (stayed in Skegness for a
while) 2hrs is was the time we got there in which isn't that bad
considering our 3 yr old walked all the way!!!
On the way back we walked the rd way (Not quite the same route
as we went besides the golf club) and our 3yr old was in pushchair
so wasn't as slow this took us 1hr 20 Min's which was a good
pace.
So depending on your pace you could do it quicker or slower if
you have children in tow, but is a nice walk for anyone.
