Louisville, Kentucky, offers countless miles of high-quality singletrack above ground. But underground lies the surprise: The Mega Cavern holds tacky dirt jumps and flow tracks with consistent weather, year round inside a massive cave.
Editor’s note: This article was originally published in 2015; it’s updated here after a subsequent trip to Louisville, KY., as a part of our ‘Great Urban Outdoors’ project with YETI.
As I pedal into the darkness, motion activated lights flash on. Around me, six-foot jumps, rocky turns, and steep cavern walls become illuminated. It’s a mountain bike playground, and I have it nearly all to myself. Where to start?
Beneath the urban sprawl of Louisville, KY, sits a mountain biking, dirt jumping haven. The one-of-a-kind Mega Cavern boasts more than 320,000 sq. ft. of biking and 45 different trails.
We traveled there to showcase the unique urban opportunity it offers in the burgeoning Louisville MTB scene. What first started as a limestone mine, the Mega Cavern founders turned it into a tourist attraction complete with excellent mountain biking.
On location for a YETI video shoot, we also learned all the ways Louisville is growing to accommodate bikers. Dedicated commuter paths, a 100-mile loop, and a newly-opened skills park are a few of the recent developments.

Together, with the Mega Cavern, Louisville positions itself as an urban mountain biking destination.
Mega Cavern, Mega Fun
We first rode the Mega Cavern on a Thursday afternoon, and it was nearly empty. A couple out-of town BMX riders spun laps. Trail builders crafted new jumps in a distant section of the cave.
More of a single-track rider myself, I took to the flow style berms trails with tame jumps. My first couple of run throughs were clunky. I stopped occasionally, missed turns, and didn’t ride efficiently.
But I kept riding, and as I learned which turns to take and what lines to follow, my thrill blossomed. I suddenly envisioned myself spending a lot of time down here.
I darted into pump tracks, hit steep berms, attempted whipping my back tire out, and popped up to a line of jumps. The runs are long and tiring, but rewarding.
It’s definitely a skills-focused course, and it’s just my style. It emphasizes the fun parts of mountain biking.
After nearly 15 minutes of riding, I had hit more jumps and berms than I would in an hour of riding the singletrack near my home in Minneapolis.
A near-infinite amount of trail combinations gives riders plenty of variety in the cave. After I got the hang of the style, I wanted to stay in the cave all day.
The literally hidden gem progressively gets more and more fun the longer you ride it.
Cave Features: What To Expect
The cave offers all levels of riding, with slick berms, variably sized jumps, and rocky singletrack. There are also pump track style lines, wooden skills terrain, and e-fat bike tours.
