Introduction

Rafting in Alaska isn’t just about paddling—it’s how you learn the river’s rhythm. Glenn Highway, running through the Matanuska Valley, offers raw water routes with just enough structure. Whether you’re sitting in a guided raft or steering your own, it’s the landscape that frames the moment. Fast stretches. Calm glides. Then another curve you didn’t expect.

Where to Experience It

Start with the Matanuska River—it flows close to the road, accessible, and scenic. A solid choice for mid-level rapids (Class II–III), especially near Glacier View. Further along, there’s Lion’s Head and the Chickaloon junction. Put-in points appear without warning sometimes, right off the roadside. Some groups go for a few hours. Others, for the whole day. The river doesn’t mind.

Tips for Visitors

Late May to September works best. Still, even in July, the water bites—glacial, after all. Wetsuits? Good idea. Drybags? Mandatory. Sunburn is possible too, which surprises people. One more thing: don’t fight the flow. Let the river tell you what to do next. Oh—and always check the weather twice.

Natural Features Nearby

You’ll see more than water. Jagged ridges. Grey ice walls. Pine shadows on the rocks. The Matanuska Glacier looms close, then fades behind bends. Eagles above. Moose in the brush. The raft hums on the current. Somewhere nearby, runoff trickles down from snowfields. It’s quiet—except when it’s not.

Why Glenn Highway

What makes this route work? Space. Not the emptiness kind, but space to move, stop, watch. Unlike southbound traffic zones, the Glenn keeps things light—fewer signs, more air. It’s close to Anchorage, but not too close. You’re in it before you realize. And getting out? That’s harder than you’d think, once you’ve floated through it.
