Rotten to the Core - Slaughter Pen

If you're looking for a black diamond trail at Slaughter Pen that earns its rating through balance and precision rather than big drops or gap jumps, Rotten to the Core is in a category of its own. This 1,677-foot singletrack runs along a creek corridor through a quiet, wooded section of the system and features two of the most distinctive skinny features in all of Bentonville followed by rocky technical sections that finish the trail with the same uncompromising standard it started with.

With 25,126 recorded activities and 34,618 check-ins on Trailforks, Rotten to the Core is one of the most-visited black diamond trails in the entire Slaughter Pen system. The numbers speak to a trail that rewards repeat visits and rewards them differently every time depending on how dialed your balance is on any given day.

The First Skinny — Stone to Wood

Rotten to the Core opens with a feature that immediately signals what kind of trail this is. The first skinny begins as a flat stone slab before transitioning seamlessly into a wooden boardwalk. The stone-to-wood transition is the moment that catches riders out on a first attempt.

The Second Skinny — The Elevated Log

The second feature is a different challenge entirely. A large tree was milled and elevated off the ground to create a raised log skinny that sits higher than the first. There is less margin for error here — the log demands a committed, centered line from the moment you roll onto it. Riders who've cleaned the first skinny with room to spare will find the second one recalibrates their expectations quickly.

The Rocky Tech

After clearing both skinnies the trail delivers its final act — rocky technical singletrack that winds through the creek corridor before the trail exits. It's a fitting finish for a trail that never lets up. The creek sits close enough to the trail that wildlife is a regular fixture on this section — deer are common, especially in the quieter hours of the morning.

Scope It Before You Commit

Rotten to the Core is bidirectional and can be ridden in either direction, but both skinnies are worth walking before your first attempt regardless of which way you approach. The log skinny in particular is a feature that benefits from a ground-level look before you point your front wheel at it. This is a trail that rewards riders who prepare for it and punishes riders who assume they're ready.
