Found your flow on the beginner trails? The next rung of the ladder at Brown County State Park is the intermediate trail system — more climbing, more descending, and more varied terrain, but nothing that demands expert-level technique. If you can comfortably ride the beginner loops without frequent stops, you're ready to sample these.

Before you head out: tell someone where you're riding, bring more water than you think you'll need, and make sure your bike is trail-ready. A well-tuned bike makes intermediate terrain far more fun — our service team can help with everything from a basic tune to full suspension service.

Aynes Loop — 3.4 miles

A great first intermediate ride. Aynes Loop is a rolling forest singletrack loop that introduces you to the rhythm of Brown County riding: steady climbs followed by flowing descents. The trail is wide enough to feel comfortable but narrow enough to feel like real singletrack. Expect the climbs to be longer than anything on the beginner trails — pacing yourself early pays off.

Green Valley — 5 miles

The longest ride on this list, Green Valley is a good test of both fitness and focus. At 5 miles, it's the kind of trail where you settle in, find your pace, and enjoy long stretches of forest riding. Bring snacks and water — this one will take meaningfully longer than the others listed here.

Weedpatch — 2.4 miles

Short but sweet. Weedpatch packs a satisfying ride into 2.4 miles, making it a good choice when you want an intermediate challenge without a big time commitment. It rides well as a standalone loop or as an add-on to a longer day.

Shelley — 2 miles

At 2 miles, Shelley is the most approachable of the four — a confidence-builder for riders stepping up from beginner terrain. It's a great warm-up lap before tackling the longer intermediate trails, or a relaxed option at the end of a big day.

Tips for riding intermediate trails

A few habits that make intermediate riding more enjoyable:

  • Look ahead, not down. Keep your eyes on where you want to go, especially on descents.
  • Manage your speed before the turn, not in it. Brake early, then let the bike roll.
  • Stand up. Level pedals, bent knees, and a relaxed grip go a long way on rough terrain.
  • Hydrate and snack. The longer climbs and distances here will catch you out if you're under-fueled.
