History and Significance of Black Hole of Calcutta Falls
The Black Hole of Calcutta Falls, named for its dark, pool-like base during heavy flows, is nestled in the Auburn State Recreation Area, a 40,000-acre park at the confluence of the North and Middle Forks of the American River. The name likely derives from the ominous, deep pool at the waterfall’s base, especially vivid after winter rains, though its exact origin remains unclear. The trail follows the Western States Trail, a historic route used during the California Gold Rush (1848–1855) and now famous for the Western States 100-Mile Endurance Run. The No Hands Bridge, a 425-foot-long, 150-foot-high concrete arch built in 1912 for the Mountain Quarries Railroad, is a highlight, once transporting limestone to Auburn for cement production until 1942. The area’s Gold Rush history, combined with its natural beauty, makes it a cultural and recreational gem, drawing over 500,000 visitors annually to the Auburn State Recreation Area.

Route Description
Start at Gate 150, marked by a green gate and trailhead sign indicating “Black Hole of Calcutta, 2.2 miles round-trip.” Pass two porta-potties and follow the wide, flat Western States Trail (also called Canyon Creek Trail) toward the No Hands Bridge, a 425-foot concrete arch spanning the North Fork of the American River.

After 1.1 miles, reach a wooden bridge in front of the Black Hole of Calcutta Falls, a 40-foot cascade with a dark pool at its base, especially striking in spring. Return via the same path for 2.2 miles total, or extend to the Quarry Trail or Coffer Trail for longer hikes. The trail is well-marked but lacks distance signs near the falls, so watch for the wooden bridge.
Navigation Tips
- Trail Markers: Follow the wide, obvious path to the No Hands Bridge and beyond. No specific markers indicate the falls, but the wooden bridge is a clear endpoint.
- Apps: Download offline maps via AllTrails or Gaia GPS, as cell service is unreliable. The trailhead is at Gate 150, clearly signed.
- Cautions: Avoid veering onto side trails without a map, as the area has a network of connecting paths. Stay on the main trail to reach the falls.
Best Times to Visit
- Optimal Seasons: Spring (March–May) for peak waterfall flow, wildflowers, and butterflies; fall (September–October) for cooler weather (50–70°F) and fall foliage. Summer offers swimming holes but can be dry and hot (90°F+).

- Timing: Start by 7:30–8:00 a.m. to avoid crowds and secure free parking, especially on weekends when the trail sees moderate traffic. Early morning or late afternoon offers better light for photography.
