Oak Trail is actually .8 miles but there is another trail (can't remember the name, starts with an S) that links up with it. There are construction signs saying it will open in Spring 2016, but the trails were all open. Prepare for mud!! Especially if it has been raining in San Antonio. A lot of the trail is in the woods so bring bug spray, I did brush off a tick so just be prepared for the ol' tick check afterward. I enjoyed it overall, but feel it would be much better when the ground is dry.
Nice trail for all ages, fitness levels & activities. Level well kept trails make for an easy walk,ride or run. I saw walker, joggers, bikers... dog walkers and stroller pushers. Well shaded, lots of places to sit & picnic.
Be mindful of where you are, the trails are well marked- but there's overlapping with the Salado Creek Greenway and it's easy to get turned around. I had to GPS myself a few times with the AllTrails app.
