Hiking in Brown County: Trevlac Bluffs Nature Preserve

If you’re looking for a quiet place to hike that still offers standout scenery, Trevlac Bluffs Nature Preserve is one of the best under-the-radar spots in Brown County. With two separate trails—one flat and family-friendly, the other more rugged with bluff-top views—this preserve gives you a lot of variety in a small footprint.

What makes Trevlac special is the mix of ecosystems you get to walk through. The lower trail follows Beanblossom Creek through wetlands and bottomland forest. The upper trail climbs to a scenic overlook and winds through one of Indiana’s last remaining stands of eastern hemlock trees. It’s peaceful, full of bird activity, and different from anything else you’ll find nearby.

That said, this trail system is a little different from most. The two trails are completely separate—they don’t connect—and the parking areas are small and located in different spots. The Yellowwood Trail (upper) is especially easy to miss if you’re not looking for it, so I’ll walk you through exactly where to go, what to expect, and how to make the most of your time here.

I’ve hiked both trails multiple times and rarely see anyone else, which makes Trevlac a great choice if you’re trying to avoid crowds. Just be ready for limited signage, no amenities, and a layout that takes a little planning.

What to expect at the Trevlac Bluffs Nature Preserve

The Trevlac Bluffs Nature Preserve includes two separate trails, each offering a totally different experience—and they’re not connected, which is important to know before you go.

• Bottomland Trail (Lower Loop): A short, flat, easy walk through wetlands along Beanblossom Creek. Great for families, birdwatchers, or a quick nature break.
• Yellowwood Trail (Upper Trail): A steeper, more rugged out-and-back trail that climbs to the top of a 200-foot bluff, with eastern hemlock trees and scenic views.

Each trail has its own small parking area, and because they’re located off different roads, you’ll need to choose one trail at a time (or drive between them). The trailheads are marked, but easy to miss—especially the Yellowwood Trail, which is just a pull-off along Old SR 45 with no designated lot.

Both trails are maintained by Sycamore Land Trust and offer a more remote, natural feel than many nearby hiking areas. You won’t find crowds, trail signs at every turn, or built-up facilities—but that’s part of the appeal. If you’re up for a lightly trafficked hike that feels wild and peaceful, Trevlac Bluffs delivers.

Bottomland Trail (Lower Section)

• Distance: 1.0 mile (Loop)
• Approximate Time to Hike: 25 minutes
• Trail Difficulty: Easy
• Elevation Gain: 38 ft
• 📍 Bottomlands Trail Trailhead Location: Small gravel lot along SR 45 near the 90-degree curve

What to Expect

This short, flat loop explores the wetland area along Beanblossom Creek, offering a peaceful walk through one of the preserve’s most ecologically rich areas. You’ll cross a small footbridge, pass marshy sections, and enjoy views of the bluff from below. The trail winds through lowland forest and offers a great chance to spot frogs, birds, and wildflowers depending on the season.

Trail conditions are generally dry, but can get muddy after rain. The path is well-marked and mostly flat, but has some uneven areas and dips, so it’s not a great fit for strollers unless they’re off-road capable and you’re ready for a struggle.

My Recommendation

This is a great trail for an easy nature walk—especially with kids or anyone who prefers flat terrain. It’s also an excellent add-on if you’ve already done the Yellowwood Trail or want to explore both sections of Trevlac Bluffs in one visit.

I like this loop best in spring and early summer when the wetland is active with wildlife and blooming plants. It’s also a nice quiet spot for a short winter hike when the trees are bare and the bluff views are more open.

Yellowwood Trail (Upper Section)

• Distance: 3.0 miles (Out & Back)
• Approximate Time to Hike: 1 hour 15 min
• Trail Difficulty: Moderate to Rugged
• Elevation Gain: 530 ft
• 📍 Yellowwood Trail Trailhead Location: Roadside pull-off on Old SR 45

What to Expect

This out-and-back trail climbs gradually to the top of a 200-foot bluff, offering one of the most scenic views in Brown County—especially in winter when the trees are bare. Along the way, you’ll hike through a quiet hardwood forest and pass a rare stand of eastern hemlock trees, which are nearly extinct in most of Indiana.

The trail is narrow and rugged in spots, with some switchbacks and a few short climbs. Given the elevation gain and uneven terrain, it’s more of a moderate-to-rugged-level hike.

At the top, there’s a simple bench where you can rest and take in the view of Beanblossom Creek and the surrounding valley below.

Trail markings are easy to follow, but you’ll briefly pass near private property—so be sure to stay on the signed path.

My Recommendation

This is the highlight of Trevlac Bluffs and my favorite trail in the preserve. It’s a peaceful, scenic hike that doesn’t take too long, but still gives you that “deep in the woods” feeling. I especially love hiking this one in late fall or winter, when you can really see the bluff drop and the valley below.

Because parking is limited to just a few roadside spots, I’d recommend arriving early or having a backup plan nearby (like Yellowwood or Hitz-Rhodehamel) if the lot is full. If you’re up for a relatively short-but-rewarding climb, this one’s a must-do.

Accessibility and Amenities

Parking

Parking is very limited at both trailheads, with space for only 2–3 vehicles at each location. There are no overflow lots or nearby street parking, so you’ll want to plan your visit accordingly.

• Bottomland Trail: Park in the small gravel lot along State Road 45, just before the sharp 90-degree bend.

• Yellowwood Trail: Park at the clearly marked pull-off on Old SR 45. It’s easy to miss, so watch for the brown preserve sign as you approach.

Even though I’ve never seen these lots full, the limited space means you’ll want to arrive early or on a weekday—especially during peak hiking seasons like October.

Restrooms

There are no restrooms, water fountains, or trash bins at Trevlac Bluffs. Plan to use facilities in Nashville or nearby Yellowwood State Forest before your hike, and follow Leave No Trace principles by packing out everything you bring in.

Picnic Areas

There are no picnic tables, shelters, or formal rest areas in the preserve, but the bench at the top of the Yellowwood Trail makes a nice spot to stop for water or a snack.

For a full lunch or picnic, you’ll want to head to nearby Yellowwood State Forest or Brown County State Park.

Family-Friendliness and Accessibility

None of the trails at Trevlac Bluffs Nature Preserve are considered truly ‘accessible.’

• The Bottomland Trail is flat and short, but still not stroller- or wheelchair-accessible due to uneven terrain and some root-dodging.
• The Yellowwood Trail is not suitable for strollers or young kids—it’s narrow in places, moderately steep, and better suited for older kids, teens, or adults who are comfortable with elevation and rougher trail conditions.

Tips for Planning Your Visit

What to Bring

There’s no water, signage beyond the trail markers, or amenities at Trevlac Bluffs—so it’s important to come prepared. I always recommend packing the basics for any hike, especially in remote trail systems like this one.

Best Times to Visit the Trevlac Bluffs Nature Preserve

Trevlac Bluffs is one of those rare places that feels peaceful and secluded year-round. The trails are lightly trafficked, and even on weekends, you’re unlikely to see many (if any) other hikers.

That said, each season brings something a little different—so it’s worth thinking about what kind of experience you want before you go.

• Winter & Early Spring – This is hands-down my favorite time to hike Trevlac Bluffs. The views from the Yellowwood Trail’s bluff are wide open with the leaves off the trees, and the trail is often completely quiet. I’ve had entire hikes here in the snow without seeing another soul. Just watch for slick sections if temperatures drop below freezing—especially on the inclines.
• Spring & Summer – Spring brings wildflowers and lots of bird activity, especially on the Bottomland Trail. In summer, the forest is lush and green, and the wetlands hum with life. These seasons also bring ticks and mosquitoes, so don’t forget bug spray and consider wearing long sleeves or pants.
• Fall – Cooler weather makes both trails more comfortable, and the forest puts on a great show of color—especially from the bluff overlook. This is a perfect time to hike either trail if you want a mix of beauty and solitude.

Nearby Attractions & Other Trails to Visit

Trevlac Bluffs is just one of several quiet, beautiful places to hike in Brown County. If you’re looking to turn your visit into a full day of exploring—or need a backup plan in case parking is full—here are a few other nearby spots worth checking out:

• Nashville, Indiana: Just a short drive away, Nashville is a great place to stop after your hike. Grab a coffee, browse local art galleries and shops, or unwind with a wood-fired pizza and craft beer at Big Woods. It’s also a solid Plan B if the weather turns or the trails are too muddy.
• Yellowwood State Forest: Just down the road, Yellowwood offers over 15 miles of hiking trails, a scenic lake, and primitive camping. For something similar in feel to Trevlac Bluffs, try the Yellowwood Lake Trail (4.5 miles) or the Scarce O’ Fat Trail (4.3 miles). Bonus: It’s a great alternative if Trevlac’s trailhead parking is full.
• Hitz-Rodehamel Nature Preserve: Looking for more uncrowded trails with beautiful ridge-and-ravine terrain? Hitz-Rhodehamel offers three well-marked loops (1.4 to 3 miles) just outside Nashville. It’s a favorite of mine for morning hikes or quieter weekend outings.
• Laura Hare Nature Preserve at Downey Hill: If you’re craving something a little more rugged, Laura Hare is one of the most challenging hikes in Brown County. With over 6 miles of trails, glacial erratics, and steep ridgelines, it’s a great option for experienced hikers.

Now You’re Ready to Hike at Trevlac Bluffs Nature Preserve!

Whether you’re wandering the wetlands along Beanblossom Creek or climbing through the quiet hemlock forest to reach the bluff, Trevlac Bluffs is one of the most unique hiking spots in Brown County. It’s peaceful, lightly trafficked, and packed with features you won’t find anywhere else in the area.

It’s also a great reminder that not all the best trails are in Brown County State Park. Sometimes, the most memorable hikes are the ones a little farther off the beaten path—where the views are wide open, the birds are active, and the only sounds are the wind through the trees.
