The only international airport in the Solomon Islands is Henderson Field, served by the following airlines.
Taxis from the airport to the center of Honiara are 100 SBD
Taxis are relatively plentiful and cheap in Honiara. They can be either ordered of flagged down, and cost 10 SBD per 1km. There are also frequent minibuses that operate along the coastal strip from Henderson to White River stopping making numerous stops along the way (SBD$3 any distance).
Hike to Mataniko/Matanikau Falls
Getting to this area can seem tricky but a hike to the Mataniko Falls is perfect and easy trip to make in a relaxed morning or afternoon. Locals are pretty useless at telling you where to go.
Jump in a minivan along the main drag (Mendana Ave) and ask to be let out at 'Town Council' - this is actually where mini-vans natural stop and the rough break between town and 'China town'. There you have a round-about. With your back to the sea: directly up hill (Mbokonavera Rd) takes you to the American WW2 memorial, to the left and right are the main coastal road, and the third option is to Mataniko.
Walk up this road (5mins) and cross the river. After the river you see a bank of Chinese shops on your left (buy water). Ask some local here and they will point you to take a mini-van from the corner of the first right in front of you. Take this to the end (5mins). Ask again and walk for 5mins. Keep asking locals. After a while you can't go any further and cross a river (this time without a bridge).
Someone will be waiting for you. Everyone will know where you want to go. You will be quoted a crazy fee (e.g. SB$150 access fee and SB$100 guide fee - or whatever they feel they can get away with). Negotiate to a reasonable price by local standards (especially if by yourself) and off you go with a guide.
The walk takes you through grass land and then into the forest, down a steep and often muddy slope. At the bottom you have the waterfalls (a lovely spot, but the falls are not anything particularly special).
Then you follow the river [bed] to get back. If there has been heavy rain, the first 100-300meters maybe deep enough that you can't walk (thus make sure you have something waterproof for money, phone, etc. - or are a good swimmer holding one hand above your head!). It may be the case that the water is low, so don't worry and certainly after a few hundred meters it goes to knee and then ankle depth. Keep walking and you are soon back at the point of the river you crossed to get to the village.
This is a great and not too long hike that show cases the real Guadalcanal on the door step of Honiara. You will see Japanese fox-holes and if lucky bullet casings.
The NPF Plaza about 500m north of the Markets has multiple internet cafes. The Telekom shop in Panatina Plaza, located towards the eastern part of town, also has an internet cafe. There are various Wi-Fi hotspots in Honiara which are often better and cheap than hotel Wi-Fi. Hunting down the access vouchers is not always easy.
There are many craft/souvenir shops located along the coastal strip, in particular in the NPF Plaza near the museum. Woven baskets are often sold on the roadside near Mendana Hotel. Handicrafts such as wooden carvings are also often sold outside the entrance to the Ofis (formerly known as the Rain Tree Cafe).
Additionally, the central market is a great place to by local handicrafts, jewellery and lavalavas (sarongs). The latter come in a range of fabrics and brightly-coloured dip-dyed designs.
A variety of handicrafts are also available at 'Art in the Park', located opposite the Rove Police Station, on the last Sunday of every month.
There are a number of shops selling secondhand clothing, which can be found easily along the main street and elsewhere. New clothes can also be purchased at various outlets, e.g. Ausmart (Townground), or in DJ Graphics, opposite the Central Market.
Handmade kids' clothing such as skirts can be found at the Central Market.

Note that there has been civil unrest and riots in this city, notably during the 'Tensions' period between 1999 and 2003, and briefly again in 2006. It is worth keeping up-to-date with travel advisory warnings, such as those provided by the Australian or New Zealand governments.
Pick-pockets operate in the Central Market, so always make sure to be aware of your surroundings and avoid taking too many valuables with you. While safe for the most part during the day, it is recommended to avoid walking around late in the evening, particularly in areas such as White River. The town center is relatively safe at night, although it is still recommended to exercise caution.
