Hawai’i Volcanoes Overview

Hawai’i Volcanoes National Park, a UNESCO World Heritage Site since 1987, is a spectacular showcase of volcanic activity and ecological diversity. Located on the Big Island of Hawai’i, USA, this national park encompasses approximately 505.36 square miles (1,308.88 square kilometers), making it a vast area of protected land that includes two of the world’s most active volcanoes: Kīlauea and Mauna Loa. The park provides a unique opportunity for visitors to witness the creation and destruction of land in real-time, offering an unparalleled insight into the geological processes that shape our planet.

Established on August 1, 1916, Hawai’i Volcanoes National Park is not only a site of immense geological significance but also a place of profound cultural importance to the Native Hawaiian people. The park’s landscape is a living testament to the island’s volcanic birth and growth, featuring dramatic lava flows, craters, and calderas that tell the ongoing story of the Earth’s interior forces at work.

Kīlauea, one of the most active volcanoes on Earth, provides visitors with the chance to see glowing lava flows, depending on the current level of volcanic activity. Mauna Loa, the world’s largest shield volcano, offers a different perspective with its massive bulk and extensive lava fields that have flowed down its flanks during eruptions.

Beyond its volcanic wonders, the park is home to diverse ecosystems that range from lush rainforests to barren desert-like landscapes, supporting unique flora and fauna adapted to the island’s varied environments. Hiking trails and scenic drives throughout the park allow for exploration of its natural and cultural treasures, including ancient petroglyphs and traditional Hawaiian sites.

Hawai’i Volcanoes National Park is not just a place of natural beauty and geological fascination; it’s a site of ongoing scientific research and a sanctuary for preserving Hawai’i’s unique biodiversity and cultural heritage. It offers an unforgettable experience for those seeking to understand the powerful natural forces that continue to shape the Hawaiian Islands.

Hawai’i Volcanoes National Park Highlights

Kīlauea

Kīlauea, one of the world’s most active volcanoes, stands at an elevation of approximately 4,091 feet (1,247 meters) above sea level. In terms of size, Kīlauea covers a vast area, with its summit caldera spanning about 2 miles (3.2 kilometers) in width and its sprawling volcanic terrain extending over 14,000 square miles (36,000 square kilometers).

This expansive volcanic landscape includes not only the summit caldera but also the surrounding rift zones and lava fields, making Kīlauea a significant geological feature of the island of Hawaii and a focal point of Hawaii Volcanoes National Park.

The easiest volcano lava to see is typically from Kīlauea, one of the world’s most active volcanoes. Kīlauea has been continuously erupting since 1983, making it relatively accessible for visitors to witness lava flows and other volcanic activity.

One of the most popular spots for viewing lava is from the Jaggar Museum overlook, where visitors can often see the glowing lava lake within Halema’uma’u Crater, especially at night.

Additionally, guided tours and hikes within the park offer opportunities to observe surface lava flows, lava tubes, and other volcanic features up close, providing memorable experiences for visitors seeking to witness the power and beauty of Hawaii’s active volcanoes.

Mauna Loa

Mauna Loa, located on the Big Island of Hawaii, is one of the most massive shield volcanoes on Earth, rising to an impressive elevation of approximately 13,678 feet (4,169 meters) above sea level.

It is also known for its immense size, with a summit caldera that spans about 6 miles (10 kilometers) in width and a total surface area that covers over 2,000 square miles (5,200 square kilometers).

Visitors to Mauna Loa can experience this iconic volcano in various ways. They can embark on a challenging multi-day hike to the summit, traversing rugged terrain and ascending through diverse ecosystems from lush rainforests to barren volcanic landscapes.

Additionally, scenic drives and guided tours offer opportunities to explore the volcano’s lower slopes and witness its vast size and geological features, providing a deeper understanding of the island’s volcanic history and natural beauty.

Lava Tubes

Lava Tubes are natural tunnels formed by flowing lava during volcanic eruptions, and they are among the most fascinating geological features in Hawaii Volcanoes National Park.

These underground passageways provide visitors with a unique opportunity to explore the remnants of past volcanic activity. Some lava tubes in the park, such as Thurston Lava Tube, are easily accessible and illuminated for safe exploration.

Visitors can walk through these subterranean marvels, marveling at the smooth walls, intricate formations, and eerie silence within. Thurston Lava Tube, for example, stretches approximately 500 feet (152 meters) long and showcases captivating lava formations along its path.

Exploring lava tubes offers a glimpse into the powerful forces that have shaped the Hawaiian landscape over thousands of years and provides a memorable and educational experience for park visitors.

Although not known for wildlife, Hawaii Volcanoes National Park, a land of fire and flora, provides a unique ecosystem where visitors can encounter endemic wildlife that thrives amidst its volcanic landscapes and lush rainforests.

Nēnē – The endangered Nēnē, or Hawaiian Goose, is Hawaii’s state bird, adapted to life in the park with its strong feet, perfect for lava fields.

Hawaiian Hawk – Known as ʻIo in Hawaiian, this raptor is endemic to the islands, revered in Hawaiian culture, and seen soaring above the park’s diverse habitats.

Hawaiian Hoary Bat – The only native land mammal of Hawaii, the Hawaiian Hoary Bat, or ʻŌpeʻapeʻa, flits through the park’s night sky, feeding on insects.

Hawaiian Monk Seal – Rarely seen within the park, the endangered Hawaiian Monk Seal occasionally hauls out on remote coastal areas to rest, a special sight for visitors.

Hawaiʻi ʻAmakihi – A small and resilient honeycreeper, the Hawaiʻi ʻAmakihi has adapted to a wide range of environments, including the park’s volcanic areas.

Apapane – Bright red and highly vocal, the Apapane is a common Hawaiian honeycreeper, feeding on nectar and contributing to the pollination of native plants.

Green Sea Turtle – Although more commonly seen on coastal beaches, Green Sea Turtles can sometimes be spotted near the park’s coastal areas, resting or basking.

Pueo – The Hawaiian Short-eared Owl, or Pueo, is one of the few endemic birds of prey, often seen hunting at dusk over open fields and lava plains.

Jackson’s Chameleon – Introduced to Hawaii, Jackson’s Chameleons have established populations in the park, their striking appearance and prehensile tails a curiosity among the native foliage.

Mongoose – Introduced and now considered invasive, mongooses can occasionally be seen darting across roads or trails, their presence a challenge to native birds and their eggs.

Hawaii Volcanoes National Park’s wildlife, from the iconic Nēnē to the elusive Hawaiian Monk Seal, offers a window into the unique and fragile ecosystems of the Hawaiian Islands, highlighting the importance of conservation efforts to protect these native and endemic species.
