Nāpau Crater Webcam – Kīlauea East Rift Zone

The Nāpau Crater Webcam provides a live view from the eastern side of Nāpau Crater along Kīlauea’s East Rift Zone in Hawaiʻi Volcanoes National Park. Known as the S2cam, this remote volcanic monitoring camera offers a rare perspective of an isolated part of Kīlauea that most visitors never see.

Nāpau Crater lies southeast of Kīlauea’s summit within the volcano’s East Rift Zone, an extensive area where magma has repeatedly moved underground and reached the surface during past eruptions. The surrounding landscape includes craters, fissures, lava flows, native vegetation, and terrain shaped by centuries of volcanic activity.

The S2cam looks across Nāpau Crater from its eastern side, providing a valuable view of current conditions in this remote section of Hawaiʻi Volcanoes National Park.

Unlike webcams positioned around Halemaʻumaʻu and Kaluapele, this camera focuses on Kīlauea’s East Rift Zone away from the summit. It provides another perspective on the enormous volcanic system and allows viewers to observe a landscape that is difficult to access.

Kīlauea remains an active volcano, and its rift zones are closely monitored. During periods of volcanic unrest or activity, remote cameras can help document visible changes such as steaming, volcanic plumes, new ground cracks, or eruptive activity when present.

Check Weather, Vog & Visibility

Weather around Nāpau Crater can change rapidly. Moist air moving across Kīlauea frequently produces clouds, rain, mist, and fog that may partially or completely obscure the crater.

During clear periods, the webcam can reveal the rugged volcanic terrain and vegetation surrounding Nāpau. Vog or atmospheric haze may also affect visibility depending on volcanic emissions and wind direction.

Because Nāpau is remote, webcam views are particularly useful for observing current conditions without entering the backcountry.

The S2cam should not be used by itself to determine volcanic hazards, trail access, or whether an area is safe to enter.

About Nāpau Crater

Nāpau Crater is located along Kīlauea’s East Rift Zone within Hawaiʻi Volcanoes National Park on Hawaiʻi Island. The crater occupies a remote volcanic landscape southeast of Kīlauea’s summit between the developed summit region and the Puʻuʻōʻō area farther down the rift zone.

Kīlauea’s East Rift Zone is one of the volcano’s two primary rift systems. Magma can migrate away from the summit through underground fractures within these zones, sometimes reaching the surface through fissures and vents many miles from Kaluapele.

The landscape surrounding Nāpau provides clear evidence of this volcanic history. Craters, lava flows, fissures, and areas of recovering vegetation illustrate the ongoing cycle of eruption and ecological renewal that characterizes much of Hawaiʻi Volcanoes National Park.

Nāpau is also associated with important episodes in Kīlauea’s modern eruptive history. Volcanic activity has occurred in the broader Nāpau and middle East Rift Zone area during multiple eruptive periods, demonstrating that activity at Kīlauea is not confined to its summit.

Unlike Kaluapele and Halemaʻumaʻu, Nāpau Crater is far from the park’s primary roads and developed overlooks. Access to the broader area involves backcountry travel, and conditions or volcanic hazards can affect access.

The crater’s location also produces variable weather. Rain and clouds frequently move across the East Rift Zone, while periods of clear weather reveal a striking combination of volcanic terrain and native Hawaiian forest.

The Nāpau Crater Webcam provides an unusually valuable window into this remote landscape. Combined with cameras at Kīlauea’s summit, Maunaulu, and Puʻuʻōʻō, the S2cam helps viewers see how extensive and diverse the Kīlauea volcanic system truly is.

Why Use the Nāpau Crater Webcam?

• View Nāpau Crater from its eastern side.
• Observe Kīlauea’s remote East Rift Zone.
• Check current weather and crater visibility.
• Monitor clouds, rain, fog, mist, haze, and vog.
• Watch for visible changes in volcanic conditions.
• Observe volcanic terrain and recovering vegetation.
• Compare conditions with Puʻuʻōʻō and Kīlauea summit webcams.
• View a remote area of Hawaiʻi Volcanoes National Park from anywhere.

Where is the Nāpau Crater Webcam located?

The S2cam is positioned on the eastern side of Nāpau Crater along Kīlauea’s East Rift Zone within Hawaiʻi Volcanoes National Park on Hawaiʻi Island.

Can I check road conditions with this webcam?

No. Nāpau Crater is in a remote backcountry area, and the S2cam is a volcanic monitoring camera rather than a traffic webcam. It does not provide a view of public roads.

Does the webcam show weather conditions?

Yes. The Nāpau Crater Webcam provides a useful look at clouds, rain, fog, mist, haze, vog, and general visibility across this portion of Kīlauea’s East Rift Zone.

Is the webcam live?

Yes. The S2cam provides a live or regularly updated view of Nāpau Crater. Because Kīlauea remains an active volcano, webcam imagery should not be used by itself to determine volcanic hazards or backcountry access.
