Main image

The Solomon Islands archipelago is a large, dispersed group of islands in the southwest Pacific Ocean, east of Papua New Guinea and forming part of Melanesia. It includes hundreds of islands of varied size, many with coral reefs, dense rainforest and significant cultural diversity.

Key visitor attractions in the archipelago include rich coral reefs and scuba diving on wartime wrecks, dense interior landscapes with customary villages, and World War II battle sites and memorials concentrated on islands such as Guadalcanal and the New Georgia group. Travel between islands is often by small plane, inter-island ferry or private launch and can be slow because of distances and limited infrastructure.

The islands were first contacted by Europeans in the 16th century and were variously administered by colonial powers in later centuries; during the Second World War Guadalcanal was the focus of major land and naval campaigns. In the 20th century parts of the archipelago became the independent nation state of the Solomon Islands, while some islands lie within the modern state of Papua New Guinea.

Geographically the chain stretches across the southwestern Pacific east of New Guinea, with major island groups including Guadalcanal, Malaita, New Georgia and Santa Isabel; many smaller inner reefs and atolls lie across a broad sea area.

  • Scale and travel: The archipelago contains nearly a thousand islands and is extremely dispersed; travel between islands is commonly by small planes, inter-island ferries or private boat.
  • WWII heritage and diving: Many sites of interest to visitors relate to the 1942-1945 Pacific campaigns - battlefields, shipwrecks and memorials are scattered across Guadalcanal and the Western Islands.

What to See #

  • Guadalcanal: Guadalcanal, the largest and best-known island in the chain, site of the Second World War campaign and home to the capital Honiara on its north coast.
  • New Georgia: New Georgia group, an island cluster with lagoon systems and extensive World War II sites and wreck-dive locations popular with divers.
  • Santa Isabel and Malaita: Santa Isabel and Malaita, large islands with extensive interior rainforests, customary villages and coastal reefs used for fishing and subsistence activities.

How to Get to Solomon Islands (archipelago) #

The Solomon Islands archipelago is accessed internationally via Honiara (Henderson Field, HIR) on Guadalcanal, which is the main gateway for the island group. International and regional flights (for example from Brisbane and other regional hubs) land at Honiara; from there domestic flights and boat services connect to outer islands, or charters can be arranged.

Because the archipelago spans many islands, reach-dependent onward travel is by domestic plane, inter-island ferry or boat charter from Honiara and other larger island bases-plan connections in advance.

Tips for Visiting Solomon Islands (archipelago) #

  • Use Honiara (Guadalcanal) as the travel hub for inter‑island connections - most domestic flights and boat charters to Solomon Islands outer islands depart from Honiara, so plan onward bookings from there.
  • Travel in the drier season (roughly May-October) when sea and air connections are more reliable and diving/WWII wreck visits have better conditions; many remote islands are inaccessible in the wet season.
  • Arrange inter‑island transfers, dive trips or guided cultural visits through reputable local operators in advance - many of the archipelago's best WWII wreck dives and cultural experiences (and the less‑visited Western Province) require prebooked charters.
