Adventure brief
Hidden Waters: Two Days in the Middle Box of the Rio Grande
The Middle Box is a pristine, under-pressured canyon of the northern Rio Grande where guides from Far Flung Adventures shuttle guests into a secluded stretch of river for remote wilderness camping, fly fishing and days of slow float-and-fish. The route threads past dramatic cliff walls, seldom-visited archaeological sites and relics of early 20th-century human activity while offering close encounters with river otters, large raptors and herds of bighorn sheep.
The Middle Box of the Rio Grande is a narrow, remote canyon cut into volcanic flows and carved by the river across northern New Mexico. This two-day guided trip — Middle Box Fly Fishing, Camping & Floating - 2 Day — meets at Far Flung Adventures Boathouse • 15 NM 522 El Prado NM 87529 and delivers anglers and outdoor lovers into a wild, little-pressured stretch of river inside the Rio Grande Del Norte National Monument and Wild Rivers natural area. Aboard rafts and on foot you’ll fish runs and pocket water that produce trout uncommon elsewhere in the southern Rockies. Towering canyon walls, polished boulder chutes and braided riffles frame the water while osprey, other birds of prey, river otters and herds of bighorn sheep move along the cliffs. The trip also passes human artifacts: the crumbling hideout of an early 20th-century horse thief, an abandoned mining site and two seldom-visited archaeological sites that hint at long human ties to this corridor. The itinerary is deliberately unhurried. After a shuttle to the Cebolla Mesa trailhead and a guided one-mile descent, guides and packers set camp while you fish the Middle Box. Expect a camp set below steep walls, a multi-course hot meal around a fire, and mornings that start with fresh coffee and the sound of the river. Day two extends fishing time with an easy downstream float to the John Dunn Bridge takeout and a short drive back to Taos-area roads and the boathouse. This trip is unique because the Middle Box receives almost no pressure; Far Flung’s guided runs are among the few multi-day services operating here. That seclusion amplifies wildlife encounters, improves fly-to-fish ratios and preserves the feel of a real wilderness overnight. Accessibility is earned: the route requires walking, wading and occasional boulder-hopping, plus the uphill return logistics, so the experience favors fit beginners through experienced anglers who can handle uneven terrain. Bring quality waders and waterproof layers, a full fly box tuned for trout, sun protection and a commitment to Leave No Trace camping—this is pristine, fragile country. Guides provide local river knowledge, safety systems and backcountry cooking so you can focus on the fishing and the canyon’s quiet drama. For anglers who want a concentrated, remote wilderness escape close to Taos, this two-day Middle Box run is a rare combination of exceptional trout water, dramatic canyon scenery and genuine backcountry camping that rewards preparation and patience. Spaces are limited on this guided run; expect professional guides and packers to manage gear and safety, and consider upgrading to Far Flung’s three-day option for extra fishing time and deeper access—book early during shoulder seasons to maximize wildlife viewing and avoid high summer heat and bring layered clothing.

Highlights
Outing Highlights
Dramatic canyon walls and a truly remote river corridor
The Middle Box runs through a breathtaking canyon—a wild, little-known stretch of the Rio Grande where the river hugs steep walls and the scenery is largely untouched.
A pristine, low-pressure fishery
This section of the Rio Grande is noted as an exceptional fishery with very little angling pressure, giving anglers time to explore big, productive holes and rare fish-holding water.
Remote camping and cultural discoveries
In addition to wilderness camping, the float passes human-history remnants—an early 20th-century horse thief’s hideout, an abandoned mining site and two seldom-visited archaeological sites—plus reliably good wildlife sightings.

What the two-day trip feels like
You meet at Far Flung’s boathouse north of Taos, shuttle to the Cebolla Mesa trailhead, and descend into the Wild Rivers natural area with packer support to reach the river’s edge. From the put-in the pace is unhurried: guides get camp established while anglers fish the outstanding holes, evening meals are served around a campfire in the canyon, and the following day begins early with more floating and fishing before a takeout at John Dunn Bridge and a short drive back to the office.
