Are you looking for a true expedition? Aniakchak National Monument is the United States’ least visited national monument . It’s so far away from anywhere.  If you are a true adventure addict and enjoy getting off the beaten path to do some exploring, this trip is a once in a lifetime experience. 

 Ouzel expeditions has the most experience on the Aniakchak River in Aniakchak National Monument. We’ve been rafting it for over 30 years.  Just ask the Park Service. They often have people call us about what it’s like there and when to go there, since even some of the park service members haven’t been there.   Ouzel is also the only outfitter who guides fishing trips on the Aniakchak River.  


Aniakchak caldera pictured above  with Surprise Lake inside lies some 400 miles southwest of Anchorage. It’s an hour and a half one way in a Beaver under the best weather conditions, from King Salmon.    You can see the upper inlet stream, the outlet of the lake through the gate.  There are hanging glaciers near the Gates. 

The Aniakchak dumps in the Pacific Ocean on the south side of the Alaska Peninsula.  It’s a two stage river. The upper half is pretty much downhill all the way. The second half is a leisurely slow fishing river with almost no drop per mile.  Just getting to the river is worth the trip.





Your foot prints might possibly be the only ones inside the Caldera.

Upon exiting the float plane that lands on Surprise Lake and stepping out onto the crater floor, you feel like a space traveler landing on a distant planet. The rugged volcanic world extending for 6 miles is enclosed by steep rock walls where nature is still trying to add a touch of green to the barren landscape. The river running out to the ocean beckons, but for the first couple days you have the opportunity to explore the sculptural topography left by the volcanic eruption of 1932.

The emerald green lake has rusty orange warm springs. The large cobbles of volcanic rubble provides an ideal environment for Arctic Ground Squirrels and Arctic Foxes. Occasionally caribou walk by inside the caldera. The lack of vegetation makes the hiking easy and enjoyable. Those who want more adventure can hike to the top of the crater wall and enjoy views of the Bering Sea. The Pacific Ocean on the south side and Bristol Bay on the north make this one of the most spectacular panoramas imaginable.
