Better to park at the trail head marked on the map found at
www.chattbike.com. Much more fun ride in. Hang a left when you hit the Jeep road and you will come to the point. Great view!
On other thing. Not all trails lead to the point. Mushroom Rock tril turns right off the Jeep rad if you come from The sportsmans Club and it never goes towards the point. Getting out can be tricky if you don't know the trails. Not hard to explain but better to knwo before you ride.
My favorites in the Chattanooga area so far are:
Edwards Point
Chilhowee - Slick Rock Trail
Tanasi System - Chestnut Loop and Down TR Express.
Lula Lake Land Trust (Closed to Public, Must ride with Bike Club)
Hope this helps for future rides.
