The country
The Alaska Peninsula here was violently reshaped by the 1912 eruption of Novarupta, burying valleys beneath hundreds of feet of ash. Today, the Valley of Ten Thousand Smokes presents a barren, pumice-covered wasteland contrasting sharply with the area's explosive green coastal marshes.
Why enthusiasts come
While casual tourists visit for bear watching at Brooks Camp, serious backpackers venture onto the ash plains for a surreal, lunar trekking experience. The sheer oddity of deep river canyons carved through ignimbrite tuff draws geology enthusiasts worldwide.
Top experiences
Fording the Lethe River to hike the barren ash plains offers an incredibly disorienting but rewarding traverse of recent volcanic destruction. Coastal wilderness camping along the Katmai coast guarantees daily sightings of massive brown bears foraging for clams.
Planner-relevant notes
Flights from Anchorage to King Salmon, followed by floatplanes, are required to access the backcountry zones. Water sources on the ash plains carry heavy silt loads and require extensive settling before filtration. High winds frequently sweep down the valleys, tearing apart weak tents.
Field notes
- Bear resistant food containers are strictly required everywhere in Katmai.
- Ash severely degrades zippers; keep gear sealed and lubricated.
- Navigating the valley in heavy fog relies entirely on GPS due to featureless terrain.
- Stand clear of riverbanks in the valley; the pumice walls are highly unstable.
