Fiji: Holding Paradise Together
On Castaway Island in Fiji, a resort is doing something unusual: treating the reef, the forest, and the people between them as a single system. A story about paradise, and the quiet, unglamorous work of keeping it alive.
The boat rounds the reef and the world narrows to sensation. The open ocean crossinghad taken hours, deep water, dark and rolling, the horizon offering nothing but more horizon. Then the colour begins to change beneath the hull, navy giving way to teal, dissolving into the pale, glass clear green of the shallows. Ahead, Castaway Island rises from the Ocean like something conjured rather than found a 70-hectare wedge of forest, white sand and volcanic rock set into the Mamanuca archipelago off the coast of Fiji. Palm trees arc overhead, their fronds catching salt wind. From the shore a song drifts out over the water, and as the boat docks, it ends in a single, resonant word: ‘Bula!’
Welcome.
Stone pathways wind between thatched bures (a traditional Fijian cottage or bungalow) half-hidden in dense hibiscus and frangipani, and the air carries the particular sweetness of the tropics salt, bloom, and something faintly resinous drifting down from the forested ridge above. Standing here, it’s easy to believe that paradise is effortless, that it simply exists, like a photograph of a place you’ve always half-remembered.
Tourism contributes approximately 40% of Fiji’s GDP, and islands like this one are at the centre of that economy. But the archipelago also sits at the front line of a different reality. Fiji is one of the world’s most vulnerable nations to climate change: beach erosion is eating into shorelines, cyclone tracks are intensifying, coral bleaching events grow more frequent with each passing decade. The reef, the forest, the beach, each is under pressure from forces that predate any single resort’s existence.
What Castaway Island Resort has chosen to do about this systematically, since the late 1990s is what the team describes as a ‘ridge to reef’ approach: an integrated framework that considers the whole watershed, from the forested ridgeline above the resort down through the island’s interior, across the beach, and into the reef systems beyond the breaker line. It’s not a slogan, it’s a way of making decisions.
The Ridge: A Forest Most People Never Think About
The hike to the ridge above Castaway is steep and brief and entirely worth it. The view at the top opens in all directions ocean to the horizon, the other Mamanuca islands scattered like green punctuation marks across blue water. But what’s most striking up here is the forest itself.
Most people thinking of Fiji’s forests imagine rainforest the lush, damp, cathedral-like density of the tropics. This is a dry forest, and it’s a different kind of beauty entirely. The trees are low and twisted, their bark thickened against drought, their canopies sparse and silvered by wind. It is, in fact, one of the most ecologically significant landscapes in the Pacific, and one of the most threatened. Fiji’s tropical dry forests contain over 300 plant species, approximately 96% of which are endemic to the archipelago. Yet they have been reduced to fragments by fire, feral animals, agriculture and decades of inattention.
A small percentage of what remains exists here in the Mamanuca Islands. In 2025, a Memorandum of Understanding was signed between Castaway and the traditional landowners from the Mataqali Ketenamasi of Solevu village, formalising the Environmental Restoration of Qalito Island Forest. The goal is to return the island’s forest to its pre-colonial state removing invasive goats, rats and cats, propagating indigenous tree species, and reintroducing native flora. Dry forest seed collection is already underway.
Among the species the project hopes to recover is the Fiji crested iguana, Brachylophus vitiensis, long-bodied, lime-green, and adorned with white bands. Once widespread across western Fiji, it now clings to a handful of island refuges. A pilot reintroduction is planned for 2026, following multi-year predator removal and habitat restoration.
None of this is incidental to the resort experience. What happens on the ridge soil stability, water infiltration, wind buffering has direct consequences for what happens on the beach and in the reef below. The ridge is not a backdrop, it’s infrastructure.
The Reef: What’s Being Grown Back
Fiji has among the most extensive coral reef systems in the Pacific Ocean – over 10,000 square kilometres, covering an area larger than many small nations. These reefs are critical food sources: Fijian communities obtain around 75% of their dietary protein from the Ocean. They are shoreline protection against storm surges, and they are the foundational reason tourism works in Fiji at all.
They are also, in many places, dying.
Marine heat waves in 2000, 2014, 2023 and 2024 each caused mass bleaching events. Cyclone Winston in 2016, one of the most powerful tropical cyclones ever recorded in the Southern Hemisphere, tore apart reef systems across the archipelago. The effects of overfishing, coastal development and warming waters are compounding.
Just offshore, in the shallows where sand gives way to coral rubble, the restoration work is visible if you know where to look. Steel frames – artificial reef structures – are anchored to the seabed, coral fragments growing in careful rows from each one, clipped from healthier sections of reef. Nearby, nursery tables hold baby corals suspended just below the surface, grown out for six to ten months until large enough to transplant back onto damaged reef. The team maintains these structures through regular dives clearing algae, monitoring fish populations, watching for sediment loads that drift down from the ridge after heavy rain. Coral grows at between two and ten centimetres per year, so it’s exacting, slow work.
‘The reef is not something separate from us,’ says Kolinio Mataiyaga, Environmental Officer for Castaway, emerging from the water with a scrubbing brush and a handful of invasive algae. ‘If it goes, everything changes.’
Guests are invited into this work directly — planting coral fragments, joining the boat run that drops a freshly seeded structure to the seafloor, snorkelling through the nurseries with staff who can read the reef’s condition the way a farmer reads a field. The intention is that they leave not just with photographs, but with some understanding of what a reef actually is, and what it would mean to lose one.
The Weight of Vanua
There is a Fijian concept, vanua, that doesn’t translate easily into English. It encompasses the land, the sea, the people and the spiritual relationships between them not separate categories but a single, integrated essence. To damage the reef is a rupture in a web of relationships that includes the living, the dead and the not-yet-born. To restore the forest is an act of cultural continuity.
Castaway is a commercial resort and its sustainability programs exist within an economic framework. But walking these stone paths, talking with the staff and with Andrews about the decades of incremental work, what becomes apparent is that the best of what is happening here is animated by something more than commercial calculation. Behind it lies an operational infrastructure most guests never see: kitchens where food waste is segregated at source, organic scraps diverted to local pig farmers or fed into a biogas system; glass bottles crushed and reused as decorative sand; recycling shipped off-island at considerable expense; 120 staff trained not just in service but in the ecological rationale behind each conservation practice. None of it is perfect, but what the systems represent is intention and sustained follow-through. On an island like this, that difference is everything.
Paradise is not a backdrop. It’s a system fragile, intricately interdependent, perpetually in need of tending. What Castaway Island shows, imperfectly but unmistakably, is that tending it is possible. That the work is worth doing. And that the ridge and the reef and the people in between can, with enough care and enough humility, hold together.
Fiji is one of the nations least responsible for global carbon emissions and most exposed to their consequences. The bleaching events were caused by warming Fiji did nothing to create. The cyclones draw their energy from Ocean surfaces heated by industrial economies on the other side of the world. The country is doing the work of climate adaptation with a fraction of the resources available to the nations whose emissions created the problem.
