Overview

Chestnut Branch is a short, punchy connector that climbs from the Big Creek Ranger Station up to the Appalachian Trail. If you’re just doing Chestnut Branch itself, plan on about 4.2 miles total out-and-back to the AT junction (roughly 2.1 miles one way) with around 1,200–1,300 feet of elevation gain. It’s a consistently uphill walk shaded by rhododendron and mature hardwoods, with mossy rock gardens and the sound of a lively creek for company. Expect a steeper final push before you pop onto the AT.

Why hike it

This is the quickest footpath from Big Creek to the Appalachian Trail and a popular first leg toward Mount Cammerer. On its own, it’s a quiet, green tunnel of a hike—no big views here—but the forest ambiance, cool shade, and creekside feel make it a satisfying workout. Keep an eye out for remnants of old homesteads (rock walls, posts, metal artifacts). They’re protected—look, don’t touch.

Route options

  • Out-and-back to the AT: 4.0–4.2 miles total. Smooth lower tread, getting rockier near the top; the last 0.2 miles are the steepest.
  • Loop via the AT and Davenport Gap: about 5.5 miles total with ~1,300 feet of gain—nice variety and an easier descent.
  • To Mount Cammerer: a big, rewarding day at roughly 11.5 miles round trip and ~3,500 feet of gain via Chestnut Branch → AT → Mount Cammerer Trail to the stone fire tower with panoramic views.

Trailhead and logistics

Start at the Big Creek Ranger Station/Big Creek Campground area, about 2.3 miles from I‑40 Exit 451. There’s a hiker lot and facilities at the ranger station, but parking is limited on busy days—arrive early. Cell service is spotty; save maps for offline use.

Conditions and what to expect

Shade most of the way with a steady grade; it can be wet and muddy after rain, and footing grows rockier near the top. Summer brings bugs (mosquitoes and occasional yellow jackets), and brief afternoon storms can make the tread slick. Bears roam this area—give them space and follow standard bear safety.

Tips

  • Poles help on the sustained climb and the steeper final stretch.
  • If you want views, continue beyond the AT toward Mount Cammerer; Chestnut Branch itself is about the forest, not vistas.
  • For a gentle cool-down after your climb, stroll Big Creek Trail to Mouse Creek Falls and back for an easy add-on.

Best time to hike

Year-round, but cooler mornings are best—especially in summer when heat, humidity, bugs, and pop-up thunderstorms are common. Weekends and peak seasons fill the Big Creek parking early; weekdays and shoulder seasons are quieter. After heavy rain, expect mud and slick rocks.

Pros

  • Fastest on-foot access from Big Creek to the Appalachian Trail
  • Shaded, creek-cooled climb that stays comfortable even on warm days
  • Subtle history with protected homestead remnants along the way

Cons

  • Limited parking at Big Creek fills early on busy days
  • Often muddy and slick after rain with a rocky, steep finish
  • Occasional yellow jackets in warm months

Parking

Park at the Big Creek Ranger Station/hiker lot near Big Creek Campground, about 2.3 miles from I‑40 Exit 451. Arrive early; spaces are limited.

Caution

Sustained steep climb with a very steep final stretch; muddy and slick after rain; rocky footing near the top; occasional yellow jackets and active bears; summer thunderstorms and spotty cell service—download maps offline.
