Thing to Do
Fish the East Fork Headwaters
NPS/Sarah Hall
Before the backcountry vehicle route opens for the summer, antsy anglers with a valid New Mexico state fishing license may fish the park's premier frontcountry stream: the East Fork Jemez River. Brown trout and rainbow trout are the dominant species in the headwaters section of this stream whereas Rio Grande chub, Rio Grande suckers, and longnose dace predominate elsewhere.
Beyond its seasonal accessibility, another benefit to fishing the East Fork is its proximity to the highway (NM-4) and Valles Caldera's main entrance. This allows anglers to enter the park on foot or by bicycle before the entrance gate opens to vehicles for the day. Vehicle gate hours in the winter season are 9:00 am - 5:00 pm, and summer hours are 8:00 am to 6:00 pm. Anglers may enjoy fishing the waters of the East Fork from dawn to dusk as long as their vehicle is parked at one of the designated pedestrian access gates.
