Navajo Reservoir is a sprawling, deep-blue impoundment straddling the Colorado-New Mexico border in Archuleta County, consistently rated among the finest lakes in the Four Corners region. Fed by the San Juan River system, the reservoir stretches through dramatic canyon country studded with sandstone cliffs, hidden coves, and winding side channels that reward boaters willing to explore upstream. Reviewers who have visited for decades say the experience keeps improving thanks to upgraded marina facilities, marked navigation aids, and well-maintained boat launches that make full-day outings straightforward even when water levels fluctuate.
Fishing at Navajo Reservoir draws anglers targeting a remarkably diverse roster of species. Smallmouth bass thrive along rocky shorelines, while northern pike grow to trophy proportions in the deeper arms of the lake. Kokanee salmon snagging in season pulls crowds to the dam area, and crappie, bluegill, catfish, and walleye round out the warm-water fishery. Trout are present as well, giving fly-fishing and spin-casting visitors year-round options. Because water levels shift significantly between spring runoff and late summer, fish-holding structure appears and disappears, so repeat trips reveal entirely new terrain each time.
Boating is the primary way to experience Navajo Reservoir. With limited accessible shoreline, a motorized boat or pontoon rental from the marina opens miles of secluded canyons perfect for camping, cliff jumping, and wildlife observation. Pontoon rentals are available through the marina store, which tries to stay open year-round and stocks supplies for day-trippers and overnighters alike. Late-afternoon thunderstorms can build quickly over the mesa country, so seasoned visitors recommend heading uplake early, sheltering in a cove if weather rolls in, and returning in the calm evening hours when the water turns glassy and the scenery is at its most photogenic.
Camping along the reservoir is a highlight, particularly on the New Mexico side where dispersed, free campsites allow visitors to set up right on the shoreline. On the Colorado side, organized campgrounds and the marina area provide more structured options with modern facilities. Families who grew up camping at Navajo Reservoir describe it as a multigenerational tradition, and the combination of warm summer water, dramatic rock formations, and reliable sunshine makes it one of the best summer destinations in southern Colorado. Visitors should pack plenty of bug spray, as mosquitoes can be heavy near the water during warmer months. Cliff diving enthusiasts also frequent the sandstone ledges along the reservoir walls, adding a dose of adventure to an already unforgettable setting.
