Aniakchak National Monument and Preserve is America’s least-visited National Park site, and we think it is one of the most interesting. Where else can you camp in an active volcano with coastal brown bears and then paddle to the sea? Join us for the adventure of a lifetime in Aniakchak Crater and beyond.

TRIP DETAILS

Picture a still hot volcano, rising from the Pacific Ocean, whose crater is home to grizzly bears as big as horses, with a mineral green lake, and some of the best hiking in Alaska. Welcome to Aniakchak National Preserve and Monument!

Aniakchak is full of surprises, from its frothy river, to the thermal springs, to the tenacious plant life growing on coarse volcanic rocks, to lakes and rivers full of salmon, to the rich Pacific coast. The Caldera was formed a scant 3500 years ago and erupted as recently as 1931. Signs of the active geology are everywhere in the area. It feels like a different planet.

From our weather worthy and comfortable camp next to the lake and within striking distance of the warm springs, we will spend our first few days enjoying the caldera in all its moods.

There are cinder cones to climb, a river to walk down with impressive rapids to view, wildlife such as brown bears, wolves, and caribou. We can hike the crater rim and look out to either the Bering Sea or the Pacific Ocean (weather permitting).

There is even a volcano inside of a volcano (Vent Mountain) we could climb. Or we could attempt to circumnavigate the 6-mile wide caldera. We can also focus our energy on photography, watching birds, or simply watching the weather and the changing light on the enormous crater walls. However we choose to use our time, the land will inspire and delight us.

After a few days of alternately traipsing around the crater, and hunkering down while the weather passes, we will prepare for the next leg of the journey, and epic rafting trip from the crater to the sea. The Pacific Ocean is only 25 miles from the crater but there is a lifetime of adventure between here and there.

We start by paddling out of the psychedelic colored Surprise lake and across the crater floor, then out a slot in the crater wall dubbed “the Gates”. Here we enter a stretch of complex and challenging whitewater where the river begins the steep descent to the ocean. The hairiest portion of the river is just a 1/2 mile stretch right at the outlet of the crater but the river is fast and fun the entire way to the sea. There is another section of whitewater as we approach the coast and plenty of mellow paddling too so we can look around and enjoy the view.

We will exercise caution around the rapids and enjoy the ride down this incredibly wild and scenic river. In addition to the slack-jaw scenery we have good chances of seeing bears fishing in the river, caribou grazing the tundra and other denizens of the park like moose, porcupine, ptarmigan, fox, and wolves.

After 3 days of boating down the river the current slacks and we are greeted by the rhythm of surf on the beach and the cries of glaucous gulls disturbed by our unexpected arrival on their lonely beach. The sand and gravel beach is littered with driftwood, occasionally whale bones, and alas, detritus from the modern world we had almost forgotten about.

We plan a final day of hiking along the coast and long evenings around the bonfire as a perfect way to wrap-up an excellent adventure in Aniakchak. There are fossils in the rocks, otters in the water and signs of the region’s history abound.

We plan this trip during the mid-summer in hopes that the weather will be mild and sunny, but we will come prepared for the famous winds and storms of the region. With luck we will see a bit of both.

Itinerary

What follows is a general flow of events. Expect the unexpected and prepare to be flexible.

July 31

Meet your guide in King Salmon for an evening pre-trip meeting.

August 1

We will board a de Havilland Beaver floatplane for a beautiful 2 hour flight down the peninsula over countless lakes and into Aniakchak Crater. The plane will land us on a bright green lake right in the heart of the caldera.  We will unload, set up a comfortable base camp, and get to exploring!

Or, if the weather is not cooperative we will kill time in King Salmon for the day and hope to fly-out the following day. The weather dictates everything we do.

August 2 - 4

We can do as much or as little as we want each day. Your guides will be available to lead hikes, interpret geology and natural history or simply suggest and facilitate your adventure.

We’ll have a wind worthy and comfortable camp, so if the wind howls, we have a place to relax and eat. But mostly we’ll be exploring the caldera on foot, investigating geothermal features, climbing high for views and scanning for wildlife. There is no end to the adventures.

August 5

After days of anticipation we don drysuits, load rafts, and start the journey to the coast.

If conditions are favorable the first couple of miles of boating in the caldera are relaxed and scenic. Once we get to “The Gates” we will stop and scout the rapids before maneuvering through this Class IV technical rapid where the Aniakchak River pours out of the crater and plummets towards the Pacific.

The most challenging rapids are about a 1/2 mile long and once through we enjoy a day of splashy and fun rafting through a lovely valley.

August 6 - 7

Two more days of boating will bring us to Aniakchak Bay. Along the way we may see bears fishing along the river which supports all 5 species of pacific salmon. We may also see other wildlife like moose, porcupine, ptarmigan, red fox, caribou, or wolves. Each bend brings new surprises and the scenery is unbeatable.

If the wind isn’t against us there will be lots of time to fish, hike, watch animals, and laze around. If the wind is against us we may have some longer days on the water and have to paddle hard to get where we are going.

Most of the lower river is fairly placid at normal water levels but we do encounter another stretch of white water below Hidden Creek which will require skill and caution. And will likely cause some whoops and hollers too.

Eventually the river mellows out and the sky broadens and we reach the Pacific Coast at Aniakchak Bay.

 

August 8

Sea otters, bald eagles, puffins, kittiwakes, harbor seals, wrens, ouzels, cormorants, river otters, bears and foxes make Aniakchak Bay feel like a paradise. The coast is rich with life and this wild beach hums with life.

We have a full day to explore, beach comb, hike, fish and goof off. Come evening we can build a driftwood fire and begin exaggerating about a trip which needs no embellishment.

August 9

Ideally the sun will shine brightly on a glassy sea and we will pack dry tents into clean bags and wait for the airplane with bare feet in warm beach sand.

More likely, the float-plane will emerge from the fog in the early afternoon and we will pile our wet gear in the plane for the 150 mile trip back up the peninsula to King Salmon arriving in time for a well earned shower and late dinner.

It is also possible that we will spend an extra night or even two on the beach. So please don’t book flights out of King Salmon before the evening of August 10 at soonest.

I genuinely feel, having traveled in South America, Australia, and Africa to remote villages and lodges, huts etc. that Alaska was the most foreign I have ever felt. And I am glad to have experienced it.
One of my biggest impressions is that I am so so very glad we had Arctic Wild as our outfitters. Michael Wald and his team were terrific and well prepared. I can’t say enough about the attention to detail and the experience of them and especially our guide Nancy Pfeiffer. I talked with other guides and with other groups. After each conversation, (trust me, they were lengthy chats as we were on a gravel runway sitting on our packs…) I thought how lucky we were to be with Nancy and Arctic Wild.

WEATHER & BUGS

Expect temperatures in the 50’s most of the time with a breeze or a genuine wind. Rain is frequent. We could get 70 and sunny or we could see a storm to remember. We might get both. Bugs shouldn’t be present, rain and fog are much more likely, but it is worth bringing a little DEET just in case there are flies in the tundra during the river trip.

Weather related aviation delays are likely. Travel insurance is essential.

"The wilderness was spectacular, the leadership perfect."
"I am just finishing my tenth trip with you guys. As always, the trip was more than I expected and I had a great time. See you next year!"
"Of all outfitters with whom we have worked (and that is quite a number), you were by far the most organized and responsive."
"That feeling of wide open wonder, the possibilities for nearly limitless wandering, and the image of those proud caribou...that will stay with me a long time"
"Our guide was an encyclopedia on legs. He was always willing and ready to teach, to talk, to listen, to do another hike, or to lie low in camp if we were beat. He truly gave us the trip we wanted!"
