Caldera-capped volcano born in the 1912 Novarupta eruption

Guide
The 1912 event was the most voluminous eruption of the 20th century. Pyroclastic flows buried what’s now the Valley of Ten Thousand Smokes, while Katmai’s summit caved in to form its caldera. Today, that caldera contains a lake and a glacier formed in historical time. The wider Katmai cluster remains active, with multiple stratovolcanoes and areas of steaming vents across the range.
There are no roads into the park from the Alaska road system. Most visitors fly into the region (with park HQ in King Salmon) and then rely on boats or limited in-park roads. Brooks Camp is the main visitor hub and the gateway to guided day trips to the Valley of Ten Thousand Smokes overlook at Three Forks. For broader volcano sightseeing or remote travel, use authorized guides and air taxis; independent backcountry travel beyond the Brooks corridor demands solid wilderness skills.
Katmai is renowned for brown bears drawn by prolific salmon runs. Learn and follow bear etiquette everywhere you go. Most of the area is national park (no sport or subsistence hunting), with a smaller preserve where hunting is allowed—know exactly where you are and follow regulations.
