Lake Te Nggano on Rennell Island is the largest inland body of water in the South Pacific and the centerpiece of the East Rennell UNESCO World Heritage site. Originally a marine lagoon, the lake was isolated from the ocean by tectonic uplift, resulting in its current brackish water composition. It covers approximately 15,500 hectares and is surrounded by dense primary forests and sheer limestone cliffs that form part of the world's largest raised coral atoll. The lake sustains a unique ecosystem, including the endemic Rennell sea snake and numerous rare avian species. During World War II, it served as a strategic base for American PBY Catalina flying boats, and several wrecks from that era remain submerged on the lake bed. Today, while it stands as a symbol of conservation in the Solomon Islands, the lake faces significant environmental pressures from climate change and the introduction of invasive species.

📋 Practical info
Getting there
Reaching this remote lake usually requires a flight to Rennell Island followed by a local transfer. Boat trips or local guides can be arranged to explore the expansive UNESCO heritage site.
Best season
The dry season, typically from May to October, is generally the best time to visit this area. Avoiding the cyclone season is highly recommended for a safer and more comfortable trip.
Terrain & paths
The surrounding terrain is often rugged, featuring limestone formations typical of raised coral atolls. Paths around the water can be highly uneven and are largely undeveloped in most sections.
What to bring
Bring sturdy footwear suitable for sharp coral rocks and uneven paths around the edges. Sun protection, ample drinking water, and effective insect repellent are essential for this tropical environment.
Parking
Organized parking is practically non-existent in this remote island setting. Visitors usually rely on local transport or walk from nearby rural villages directly to the water's edge.
Safety
Always travel with a local guide, as infrastructure is limited and the environment is very isolated. Be cautious of sharp coral edges, uneven ground, and local wildlife when near the water.
Time needed
A visit typically spans at least a full day to properly appreciate the lake's vast scale and unique ecology. Many travelers spend several days exploring the broader East Rennell conservation area.
