Upper X is a really well built and well taken care of trail, my hat off to the trail builder! Mix of some steep climbs but most of the trail is fairly ridable and I recommend riding from the South to the North and then take Trail X back. Slight savings in climbing and allows you to hit more of the trail features. Someone also has taken time to build some really cool steel sculptures along the trail.

trail needs a little trim, lots of branches and shrubs wanting to scrape up yer arms and legs so be sure to wear gloves and long sleeves!

Very fun trail . Much the same as lower x. All single track . Definitely blue not black diamond. Well maintained with multiple bridges
We hope you've been enjoying Trailforks!
