Mauna Ulu and Puʻu Huluhulu Hike (E/C/F)
Hawaiʻi Volcanoes National Park, Keauhou, Moku o Kaʻū
4 miles, elevation: 3200’, +/- 375’
On this hike, we will experience a landscape formed over a five-year eruption period – one of the longest known rift-zone eruptions of Kīlauea. We will start on the Napau Crater Trail to Puʻu Huluhulu, and take in the spectacular panoramic view from the overlook. We will then hike to Mauna Ulu via a perched lava pond. Hiking boots recommended. Bring rain gear along with your day-hike essentials. This will be an easy-to-moderate hike. ROD protocol, please. We will meet at the Mauna Ulu Parking Lot off the Chain of Craters Road. Register for the hike by calling Phyllis Chung at 808-767-3563.
Managed Decline of Fossil Fuels
By Stephen Holmes, HIG ExCom Member & Former US Department of Energy National Energy Champion
It was surprising to hear Governor Josh Green move toward LNG at a time when energy experts agree that fossil fuels are now in a state of managed decline, with investors shifting away rapidly. Global markets are awash in oil and gas, with prices often too low to cover production costs. LNG, or liquefied natural gas, actually carries a premium, as it requires an enormous amount of energy to liquefy it, followed by additional losses during long-distance transport to markets like Hawaiʻi. The infrastructure needed to support LNG also comes with a massive price tag, and ultimately, ratepayers would be the ones footing the bill.
LNG solves none of Hawaiʻi’s core energy challenges. It is not a transportation fuel for jets, cannot power our existing fleet of cars or trucks, and does nothing to advance the transition already underway toward electric vehicles. Even shipping is beginning to electrify, including oil tankers, as new low-cost, high–energy-density batteries make this shift increasingly viable.
Meanwhile, solar power in Hawaiʻi is more than capable of meeting our grid needs, at a fraction of the cost and time as fossil fuels. Some of this growth will come from utility-scale solar with battery storage, but a major and often overlooked opportunity lies in decentralized energy. Third-party financing tools such as energy savings performance contracts and power purchase agreements are about to create a solar boom. Federal tax incentives for commercial projects are still good for the next few years, and by the time they sunset, cheaper batteries are likely to make those incentives unnecessary. Attempts by utilities to simply fuel-switch aging fossil plants cannot compete.
Decentralized solar offers enormous benefits. It reduces demand on the grid, eliminates the need for new transmission infrastructure, and avoids line losses by generating power exactly where it’s needed. Batteries reduce peak demand, third-party ownership eliminates upfront costs, and no costs are passed on to the grid. This model accelerates the retirement of old, expensive power plants, attracts major investment to Hawaiʻi’s economy, and creates good-paying local jobs. Decentralized energy represents a huge opportunity.
Managing the decline of fossil fuels, while keeping the lights on and existing gas-powered vehicles operating during the transition, will not be simple. But we cannot allow elected officials to sell out Hawaiʻi’s future in an attempt to delay the inevitable.

Five Years of Protection and Conservation at Oʻahu’s Wāwāmalu Beach
By Reese Liggett, Oʻahu Group Outings Leader

January 2026 marks five years since a boulder barrier was installed at Wāwāmalu Beach (just northeast of, and adjacent to, Sandy Beach Park) along the Kaiwi coast, named for the Kaiwi Channel between Oʻahu and Molokaʻi. Wāwāmalu is a somewhat forgotten place name; earlier known as Āwawamalu, meaning shady valley, it once referred to the broader area stretching from Sandy Beach Park to Makapuʻu.
Today, Wāwāmalu Beach is often identified on maps as the undeveloped coastal area makai of the signalized intersection at Kealahou Street and Kalanianaʻole Highway. It features native-planted dunes and a wide, beautiful white-sand beach—great for walking, sitting, and surf gazing, though generally too rocky for swimming. Hawaiian monk seals are known to bask and give birth here. For decades, however, this fragile landscape was repeatedly damaged by off-roading trucks, and even sedans, driving through the dunes.
The installation of the boulder barrier in early 2021 was the result of more than two decades of political activism by Sierra Club Oʻahu Group members and allies, dating back to 2001. The effort was:
Championed by Honolulu City Council Chair Tommy Waters, following his District 4 election in March 2019, in response to strong advocacy from Sierra Club activists;
Advanced by a Hawaiʻi Kai Neighborhood Board resolution in fall 2019, which formally urged city action; and
Supported by sustained advocacy from Livable Hawaiʻi Kai Hui and the Surfrider Foundation.

Funding for the vehicle barrier was included in the City’s 2020–2021 budget, and its installation was made possible by a development permit issued during the Caldwell Administration in fall 2020. The barrier was ultimately installed in phases during January and April 2021 under the direction of Laura Thielen, then Director of Parks and Recreation in the incoming Blangiardi Administration.
The boulders themselves were sourced from Kaiwi State Scenic Shoreline lands roughly a half-mile away. These rocks had been stockpiled decades earlier by Henry J. Kaiser during the development of Hawaiʻi Kai and Kalama Valley. The only direct costs associated with the barrier were equipment rentals, excavators, dump trucks, and front loaders, to select, transport, and place the boulders along a painted alignment provided by Sierra Club activists. Those boulders remain firmly in place and on the job today.

Since the barrier’s installation, very few four-wheel vehicles have managed to breach it and drive onto the beach or dunes. However, two-wheeled motorized vehicles continue to illegally enter the area, violating Revised Ordinances of Honolulu Chapter 10 and damaging native plants while posing threats to basking monk seals. In addition, individuals feeding feral cats, also in violation of park rules, continue to support populations that spread toxoplasmosis, a disease lethal to monk seals and porpoises. While cat advocates often cite spay-and-neuter efforts, the ongoing toxoplasmosis risk to endangered wildlife remains largely unaddressed. Members of the public are encouraged to actively report violations involving motorized vehicles or cat feeding by calling (808) 529-3111.
Since October 2022, more than 600 volunteers have participated in 39 monthly conservation workdays—typically held on the third Sunday of each month. These outings have focused on removing invasive plants, collecting and sowing native seeds, and planting native coastal species sourced from other parts of Oʻahu, including the native sedge mauʻu ʻakiʻaki (Fimbristylis cymosa).
The primary invasive species targeted have been koa haole, now approximately 95% cleared, and buffelgrass, a highly aggressive African grass that remains the greatest obstacle to native plant recovery and a serious wildfire hazard.
Looking ahead, opportunities to participate in hands-on conservation at Wāwāmalu Beach will continue most months on third Sunday mornings. Upcoming outings are always listed on the Sierra Club Oʻahu Group’s hikes and outings calendar here.
