Coppertone and I decided to do a bit of walking prior to eating at a Mexican Restaurant in Napa we like. Oxbow Preserve was on our not-yet-done list so we decided on it even though we know it would not be terribly long.
Just under a half mile of the trail was paved with the rest being easy to follow singletrack. We found a great discrepency between official preserve trail map and what's actually on the ground. The most glaring is the 90 degree error on where North lies. Some of the trail differences could be chalked up to rogue trails that have since been adopted as a main trail, but not all. I think the map may have been based on some original plans that were modified in some way during installation.
Zipping back and forth to try and get all of the main trail segments we still ended up under 1.25 miles, so this is not the place to go for a serious walk. But it may serve as a nice pre or post meal walk if eating at the nearby Oxbox Market.
