Reviews Photos Tracks Chrissy Toner (79) 1 day ago N/A: 3 Completed 1 Reviews Our GPS logged this trail as 6.38 miles from gate 11 to gate 12. Add another 1/2 mile on the road between gates. Easy and beautiful walk. It is 1/2 down hill, 1/2 up. Our almost 3 yr old did about 4.5 miles of it on his own. Lisa T.
