About Honiara

Honiara is a working Pacific capital and the main gateway to the Solomon Islands. Central Market, the waterfront, museums, churches, craft stalls, and nearby World War II sites provide the urban introduction, while Guadalcanal's battlefields, waterfalls, villages, and forest roads require a trusted driver or guide. Traffic, rain, limited sidewalks, and changing local conditions make a carefully paced route more realistic than walking the entire city. Ask before taking photographs, keep valuables discreet, and confirm transport and security advice before heading beyond the center.
