All trailheads will take you there in less than a 15 minute walk, and they all will have a bit of elevation to deal with. The Oakfield Crescent trailhead is the quickest/easiest grab (the path coming to the cache location from the other direction is a little bit bumpier and has one rocky scramble), but the Oakfield Crescent trail is also the least interesting if you just make the grab and turn around (you'll miss the views). I recommend doing a loop to one of the other trailheads and back down the roads, it is a nice area.
Note that there is a large open grassy area near the cache location on the Oakfield Crescent side that has houses bordering on it; you do not need to explore that area. When you are at the location you will be 'around the corner' and not in sight of any of the nearby houses.
Cache container is a standard small lock&lock.
Congratulations to The_Incredibles_ for FTF!
