East Fork Jemez River

New Mexico

The East Fork of the Jemez River originates as a small meandering stream in the vast grassland crater of the Valles Caldera National Preserve in the Jemez Mountains of northern New Mexico. Through the upper recreational segment, the river winds its way through small riparian meadows, creating a pastoral scene. The recreational segment has one developed site, Las Conchas Fishing Access, and the Las Conchas Trailhead, which accesses Trail 137. This portion of the trail closely follows the river for a mile, and its gentle grades and spectacular scenery make this a popular stretch.

Within the wild segment, the river enters a rugged stretch of canyon where cliffs and huge boulders emerge among slopes densely covered with mixed varieties of conifers. In places, the river flows from canyon wall to canyon wall, making passage impossible without wading or using footbridges along the stream. However, anglers often hike up the box canyon to their favorite fishing spots. Occasionally, a bend in the river will lead to an open meadow alive with seasonal wildflowers. Half a mile in from the highway at each end of the box canyon, people access the river for a variety of other recreational activities. The very large boulders and deep pools in the river create popular sites for jumping and swimming. Snowplay, cross-country skiing, and snowmobiling also occur in this area.

The scenic segment of the river continues through another rugged canyon, and tumbles over the bedrock creating Jemez Falls, a cascade dropping more than one hundred feet. From the falls, the river flows through a steep canyon with limited access. The canyon opens up as it approaches the looming solid rhyolite monument of Battleship Rock; here, the riverbanks provide exquisite beauty. The many varicolored cliffs around the confluence thrust up to a typical azure sky; shadows and sunlight playing across the landscape complete a dazzling mosaic. The scenic segment is a destination for anglers from all over the state, especially the urban areas of Albuquerque and Santa Fe. Access is primarily up the river from Battleship Rock. Other visitors take Trail 137 along the ridge to McCauley Warm Spring and Jemez Falls. This affords the opportunity to experience a truly stunning landscape view across to the walls of Jemez Canyon.
