Wizard Island

Wizard Island is a volcanic cinder cone that rises above the surface of Crater Lake in Crater Lake National Park, Oregon. It formed after the caldera-forming eruption of Mount Mazama and sits within one of the deepest lakes in the United States.

The island is a compact volcanic feature with a walkable trail to its summit crater and shoreline viewpoints. Seasonal boat tours cross the lake to land at the island’s pier and allow short guided walks; shorelines offer views across the caldera’s near-vertical rims and the lake’s clear blue water. The surrounding lake has a maximum depth of roughly 590 m (1,940 ft), which contributes to the park’s striking scenery.

The cone was built by post-caldera eruptions that filled part of the caldera with lava and pyroclastic material, producing the island’s cinder-cone shape. The caldera itself formed about 7,700 years ago when Mount Mazama collapsed after a major eruption; subsequent eruptions inside the caldera created Wizard Island.

The island sits within Crater Lake in south-central Oregon, inside Crater Lake National Park. The park lies in a remote volcanic highland area of the Cascade Range, roughly 60 miles (about 100 km) north of Klamath Falls by road.

• Access: Boat landings and guided walks on the island are only available in summer; most services run in the park's summer season (roughly June to October).
• Crater depth: The lake that surrounds the island is one of North America's deepest, at about 590 m (1,940 ft), producing very clear water and dramatic cliff views from the island.
