Hiking

The Iron Horse Regional Trail offers a delightful and accessible escape, weaving through the East Bay's varied landscapes. This moderate 5.7-mile (9.2 km) hike, with a gentle 51 feet (16 metres) of elevation gain, is mostly paved and takes about 2 hours and 20 minutes to complete. You'll experience everything from the charming atmosphere of downtown Danville to serene stretches under a mature oak tree canopy, with opportunities to spot local birds along marshy creeks.

Accessing the trail is easy, with multiple parking areas like the Alamo Trailhead and direct connections to several BART stations, making it a great option for public transportation. While popular, the trail's length allows for plenty of space, and it's suitable for year-round enjoyment. Consider an early morning or late afternoon visit for cooler temperatures and fewer crowds.

This historic rail trail follows the path of the former Southern Pacific Railroad, giving it a unique character as it links residential areas, business parks, and community facilities. It's a true community asset, serving as both a recreational pathway and a vital transportation corridor, used by millions annually. Its flat terrain and multi-use nature make it a fantastic choice for families, casual walkers, and anyone looking for a relaxed outdoor activity.
