Rennell Island

Rennell Island is the larger of the two main islands of Rennell and Bellona Province (RenBel), lying at the southern edge of the Solomon Islands, well south of the main island chain. It is the world's largest raised coral atoll — a former atoll lifted above the sea, its old lagoon now forming the vast brackish Lake Tegano at the eastern end. The island is densely forested, ringed by rugged limestone, and home to a Polynesian-outlier people whose language and culture are distinct from the Melanesian majority of the Solomons. Together with neighbouring Bellona, Rennell forms one of the most remote and culturally singular corners of the country.

For travellers, Rennell's headline attraction is East Rennell, the UNESCO World Heritage area centred on Lake Tegano, prized for its raised-atoll landscape and endemic wildlife — several bird species occur here and nowhere else. The island also offers forest, karst, and the cultural experience of its Polynesian villages. WWII left its mark too, with sunken Catalina flying boats in the lake. Accommodation and access are split between West Rennell, near the airstrip, and the East Rennell lake area; reaching the World Heritage zone requires a long overland transfer across the island.

The climate is hot, humid, and tropical year-round, with the drier months from roughly May to October the most settled and the November-to-April wet season rainier and cyclone-prone. Infrastructure is minimal; bring your own gear and arrange everything through local hosts and guides.

By Plane

Rennell is served by Rennell/Tingoa Airport (IATA: RNL) at the western end of the island, with domestic flights from Honiara on Solomon Airlines. Schedules are limited, so confirm in advance. This is the usual way in.

By Train

Not relevant — there are no railways in the Solomon Islands.

By Car / Road

A rough cross-island road and track run from the Tingoa airstrip in West Rennell eastward toward Lake Tegano and East Rennell — a long, slow truck journey of several hours over poor surfaces. Arrange this transfer in advance with local operators; it is the main overland route on the island.

Rennell can also be reached by sea via inter-island vessels from Honiara, though such services are slow and infrequent.

There is no public transport. Movement around the island is by truck on the rough cross-island route, on foot along forest trails, and by canoe on Lake Tegano and along the coast. Local guides handle transport and bush walks and are needed in practice, especially within the customary-owned World Heritage area. Agree all fares and fees in advance.

• Lake Tegano and East Rennell — The World Heritage-listed brackish lake, the largest in the Pacific, with its islets, forest, and endemic wildlife — the island's premier sight.

• Endemic birdlife — Rennell's endemic birds (Bare-eyed White-eye, Rennell Starling, Rennell Fantail, Rennell Shrikebill, and more) draw birders from afar.

• Raised-atoll landscape — Dramatic limestone karst and dense forest covering the lifted former atoll.

• WWII Catalina wrecks — Sunken flying-boat remains in Lake Tegano, of interest to divers and history enthusiasts.

• Visit East Rennell / Lake Tegano — Canoe the lake, watch for endemic birds, and explore the World Heritage area with local guides.

• Birdwatching — Seek the island's endemics along forest edges and the lakeshore.

• Bush walking — Trek the forest and karst with a guide.

• Snorkelling and diving — Snorkel the lake or, if equipped and experienced, dive the Catalina wrecks; bring your own gear.

Food is simple village fare provided by hosts — fish, root crops, rice, coconut, and tropical fruit. There are no restaurants. Self-caterers should bring supplies. Vegetarian eating relies on the local staples.

Treat or boil local water, or bring bottled water; Lake Tegano is brackish and not for drinking. Fresh coconut is available. Alcohol is scarce; respect local customs. Nightlife is absent.

Accommodation is in small, family-run village lodges and guesthouses, mostly around Lake Tegano in the east but with some simpler options near the airstrip in West Rennell. Expect a handful of basic bungalows, modest rates, and very limited capacity; book in advance through local operators.

There is no real shopping beyond basic village goods. Bring everything you need and carry cash in Solomon Islands dollars for guide fees, lodging, and customary access charges, as there are no banking facilities.

• Lake Tegano (East Rennell) — the World Heritage lake and the island's main destination, if not already your base.
• Bellona Island (northwest, in the same province) — a smaller raised-atoll island with white-sand settings and Polynesian culture.
• Honiara (by air, on Guadalcanal) — the national capital and main transport hub.
