Big Arsenic Trailhead provides access to the Rio Grande via a steep, well-maintained 1. 4-mile trail with 680 feet of elevation loss, featuring switchbacks and scenic gorge views.

The trailhead includes a day-use parking area, information kiosk, and pit toilets, with a $3 day-use fee; primitive river campsites are available at $5/night.

This is a popular access point for anglers and hikers seeking Rio Grande access within the Wild Rivers Recreation Area, though the steep descent requires good physical condition and sturdy footwear.
