Honestly, I didn't think I was going to enjoy this trail. Most Nashville residents don't go downtown unless it's for a show or work. What I found were almost endless opportunities for photography (my personal image folder for this trail has hundreds of photos), people watching, and learning about my city from ancient geology to river commerce. I also grabbed some fresh veggies at our Farmer's Market before I drove off for the day.
The trail surface is well maintained asphalt. It's pretty much flat which makes for an easy ramble. Any hills are totally workable. There are several portalets so no need to worry about finding a bush.
The Metrocenter levee trail is closed until summer of next year (2012) for reconstruction that I assume is due to damage from the flood.
If you're a visitor or even a long time resident, please take a few hours to meander about. Maybe even pack a lunch for kicking back on the riverfront lawn and enjoying the sunshine.
