Papahana Kuaola, situated in the Ahupua’a of He’eia in the Ko’olaupoko district on the island of O’ahu, is a Hawaiian environmental education organization committed to cultural and ecological restoration and revitalization.

Since its establishment as a non-profit in 2006, it has grown in popularity due to its community-oriented mission connecting culture, community, and economy with the land, water, and people. Activities range from organizing sustainable farming workshops and managing community-based restoration projects to hosting cultural education programs for schools.

Volunteering at Papahana Kuaola is streamlined through their website, where prospective volunteers can RSVP for an event and learn about necessary tools or equipment.

Volunteers might work on projects like stream restoration, removing invasive plants, and learning about the native flora. Despite the strenuous nature of the work, the rewarding experience provides an immersive understanding of the Hawaiian ecosystem and cultural practices.

Set between the ridges of the Ko’olau mountain range, the vibrant greenery, ponds, and lo’i of Papahana Kuaola create an unparalleled volunteering setting. With a strong sense of community and knowledge about Hawaiian culture, this organization serves as an enriching space for both locals and visitors looking to make a positive environmental impact.

Hui O Ko’olaupoko, a non-profit nature preservation organization situated on O’ahu island, is dedicated to protecting and restoring the Koolaupoko region’s water resources and marine ecosystems. Established in 2007, the organization operates under the mission statement: “Protecting ocean health by restoring the ʻāina: mauka to makai,” which speaks to its commitment to mitigating the effects of pollution and ill-maintained land on waterways and the ocean.

Focusing on ecosystem restoration and stormwater management, it offers various volunteering opportunities to educate people on the importance of these areas and encourage community participation in its initiatives.

Volunteering at Hui O Ko’olaupoko, located at 750 Kaha Street, is a hands-on experience where volunteers get involved in strenuous tasks such as clearing out invasive species to make room for native plants to thrive. Despite the tough labor, the opportunity is enriched by the natural beauty of the location, brimming with native plants and wildlife, and the knowledgeable guides who share insights about the local flora and Hawaiian Mo’olelo (stories).

A well-coordinated process facilitates volunteering, where individuals sign up via a form on the organization’s website and receive detailed follow-up emails, ensuring they are well-prepared for the experience. The organization’s dedicated approach to environmental preservation makes it a rewarding and informative volunteering opportunity.

Kaloko Inlet Restoration

Volunteering at the Kaloko Inlet Restoration at Kaiwi State Scenic Shoreline is more than just helping out. It’s a chance to play a part in protecting Hawaii’s special environment while experiencing the beautiful scenery of the island. For those who are 16 years old or younger, it’s required to have a parent or guardian there the whole time. This makes sure everyone is safe and doing what they should be.

When it comes to what you should bring, it’s recommended to wear sturdy shoes and long pants. This is to protect you from the rough ground and any poking bushes. Also, don’t forget to bring a bottle of water to drink, as it can get quite hot. Don’t worry about any other tools you might need for the work, because those will be provided for you when you get there.

The work you’ll be doing is split into three main tasks. The first task, or priority, is to get rid of invasive plants. This involves digging up and cutting down mangrove, kiawe, and koa haole shrubs that are not native to the area. This helps make room for plants that originally grow in Hawaii.

The second priority is to move the cut plants from where they were to another spot up a hill. This spot is called a ‘dry staging site.’ It’s where we put the plants we cut down until we can dispose of them properly.

The third and final priority is to pick up any litter found along the coastline and trails. This keeps the area clean and safe for all who visit and helps protect the wildlife that live there.

The Kaupō Hillside Coastal Restoration project offers a special opportunity to make a real difference in preserving Hawaii’s natural beauty. However, due to the challenging terrain and proximity to a busy highway, we advise that volunteers under the age of 16 should not participate in this event for safety reasons. Those who do attend should come prepared.

Wearing sturdy shoes and long pants is essential for protection against rough ground. As Hawaii can get quite sunny, sunscreen is important too, and bringing water is highly recommended to stay hydrated. No need to worry about other tools, as everything else you’ll need will be provided.

The work focuses on two key areas. The first is the removal of invasive and non-native plants. As a volunteer, you’ll help cut down koa haole trees, remove the stumps, and get rid of non-native grasses and other plants. The second task is picking up trash. You may find abandoned campsites that need cleaning up and will deal with them as needed.

I have personally done this event and can concur that it is one of the best on the island, read more about it here.

Volunteering at Keawawa Wetland provides an amazing opportunity for families to get involved in hands-on conservation work while experiencing the natural beauty of Hawaii. This opportunity is open to everyone, making it a wonderful way for families to spend time together while also giving back to the community.

Because the work involves being outdoors, volunteers should come prepared.

Volunteering at the historic He’eia Fishpond offers a rewarding opportunity for those aged 12 and up to contribute to the preservation of this ancient Hawaiian aquaculture site.

With its unique blend of cultural heritage and conservation efforts, it’s not surprising that He’eia Fishpond is a highly sought-after place for volunteering.

USS Missouri

13+ requires an adult, 16+ may come unattended

a large ship in the water

Volunteering at the USS Missouri, also affectionately known as the “Mighty Mo,” can be an exciting, rewarding, and highly educational experience. One of the significant advantages of volunteering here is the chance to see areas of the ship typically off-limits to the general public. This comes especially when you participate in cleaning tasks, which can take you to hidden corners and secret passages within this colossal ship.

Volunteers can engage in a variety of activities like sanding, sweeping, touch-up painting, and moving items. Sweeping can be particularly adventurous, as it may take you up to level 06, the highest accessible deck on the ship, providing a unique view of the vessel and the surrounding harbor.

And don’t worry if you’ve never done some of these tasks before. The friendly staff and fellow volunteers are always ready to guide you, making sure you know exactly what to do.

However, there are certain age-related rules you should be aware of. If you’re under 13, you’ll need a parent or guardian with you. This is for safety reasons and to ensure younger volunteers get the guidance and supervision they need. But don’t let that discourage you – it can be a fun, shared experience with your family.

If you’re 16 or older, you’re allowed to volunteer independently. This is a great opportunity for high school students to learn new skills, get a taste of history, and even contribute to their community service hours.

There is a specific article on volunteering here and you can read the details of the experience to get a better understanding.
