Havasu National Wildlife Refuge

The lower Colorado has supported people for a very long time, and this stretch lies in the country of the Mojave and other river tribes, whose descendants belong to the Fort Mojave Indian Tribe and the Colorado River Indian Tribes. Petroglyphs and other traces along the Topock Gorge speak to that long presence, and the river and its marshes remain culturally important to the tribes today.

The refuge itself was established in 1941, part of a wave of Colorado River conservation as the river was being remade by dams. Where much of the lower Colorado was straightened, channelized, and drained, Havasu preserves a piece of the old river, its marshes and backwaters, as habitat rather than infrastructure. That makes it a refuge in the fullest sense, a place set aside for the wild life the rest of the river has largely lost room for.

The Topock Gorge is the refuge's scenic heart, a stretch where the Colorado has cut down through hard volcanic rock, leaving steep, colorful desert walls rising straight from the water. Paddling or boating through it, you pass rock spires, side canyons, and cliffs where bighorn sheep sometimes stand watching, all in a setting that feels far older and wilder than the river resorts just downstream.

Upstream lies the Topock Marsh, a large, shallow wetland of open water, reeds, and mudflats fed by the river. This is the biological engine of the refuge, a rare expanse of marsh in a desert, and it is what draws the great numbers of birds. The contrast is what makes the refuge special, hard rock and open desert on one hand, soft green marsh and still water on the other, the two knit together by the same river.

Birds are the reason the refuge exists, and they are its great spectacle. The marsh and river host herons, egrets, ibis, and huge numbers of ducks and geese in the cooler months, along with grebes, pelicans, and the occasional bald eagle. It is also vital habitat for the endangered Yuma Ridgway's rail and the southwestern willow flycatcher, secretive marsh birds that depend on exactly this kind of wetland.

The desert around the water holds its own life. Bighorn sheep travel the cliffs above the gorge, and coyotes, bobcats, and jackrabbits range the dry slopes, while lizards and rattlesnakes shelter in the rocks. Beavers and muskrats work the backwaters, and the mix of river, marsh, and desert packs a remarkable range of wildlife into one long green corridor.

Winter is the prime season at the refuge, when the marsh fills with wintering waterfowl and the birdwatching is at its best, and the desert heat has finally let go. Spring is beautiful too, with migrating birds moving through and mild days for a river trip.

Summer along the lower Colorado is punishing, with fierce heat off the water and open desert, so a visit then is best in the early morning or reserved for the river itself, where the water offers some relief. Fall brings cooler air and the first returning waterfowl, easing the refuge back into its busy winter season.

Havasu National Wildlife Refuge protects a vital stretch of the lower Colorado River between Needles, California, and Lake Havasu, spanning the Arizona-California border. Encompassing the scenic Topock Gorge and the Topock Marsh, it safeguards rare desert-river habitat, from rugged canyon walls to lush wetlands, that supports abundant birds and wildlife. A haven for migratory waterfowl and a paradise for paddlers and birders, the refuge offers beautiful river scenery, wildlife viewing, and peaceful recreation, preserving one of the last relatively wild reaches of the lower Colorado River in a striking desert setting.

You can paddle a kayak or canoe through the stunning Topock Gorge, where towering canyon walls rise from the clear Colorado River, watch abundant birdlife including migratory waterfowl especially around the Topock Marsh, fish, and enjoy boating and wildlife viewing in a beautiful desert-river setting. Birdwatching is a major draw, particularly in the cooler months. The combination of dramatic gorge scenery, tranquil marshes, and rich wildlife makes the refuge a rewarding destination for paddlers, anglers, birders, and anyone seeking the wild beauty of the lower Colorado River.

On the water, wear a life jacket, watch for boat traffic which can be busy in season, and be aware of currents, winds, and changing weather on the river. The desert heat is intense, especially in summer, so carry plenty of water and sun protection and avoid strenuous activity in the extreme midday heat. Plan your paddling route and timing, since the gorge is remote in stretches. Respecting the water conditions and desert heat lets you safely enjoy the refuge's river, gorge, and marshes.

The cooler months from fall through spring are the best time, offering comfortable temperatures for paddling and hiking and prime birdwatching as migratory waterfowl and other birds fill the marshes and river, while summer is very hot, so early activity and ample water are essential then. Winter and spring are especially rewarding for birders. Mornings are ideal for wildlife and calm water. For the best combination of comfortable weather and abundant birdlife, plan a visit during the cool season.

The refuge lies along the lower Colorado River near the Arizona-California border, close to Lake Havasu City with its famous London Bridge and lake recreation to the south, the Route 66 town of Kingman and the wild-burro town of Oatman to the east, and Needles, California, to the north. That makes Havasu National Wildlife Refuge a scenic natural stop to combine with Lake Havasu, the London Bridge, and the Route 66 attractions of northwestern Arizona and the lower Colorado River region.
