No, the OKW/SSR path is not on that map. It is 0.93 miles (thanks for the measurement to Caskbill) from Cirque to OKW.
From SSR, depending on your location it could be a little farther. To get to the path you need to go down to the LBV golf clubhouse and cross the cart bridge across the canal. (The bridge IS on the map at the lower right.) After crossing the bridge, the path goes left (to the practice green and on towards Cirque around the parking area) and to the right. Take the path to the right. It follows the Trumbo Canal all the way to OKW. You will pass the Treehouse Villas along the way where the canal divides to go to Port Orleans. Just stay on the path all the way to OKW without crossing the canal (you'd be on the golf course - and they frown on that for safety reasons). At the end of the trail, you'll be right behind Building 55 and can continue on thru OKW or just head back to SSR.
Enjoy!
