Overview
Sao Tome and Principe is a two-island nation in the Gulf of Guinea, sitting almost on the Equator off the coast of Central Africa. One of Africa's smallest and least-visited countries, it rewards travellers with rainforest-clad volcanic peaks, old cocoa estates and near-empty beaches. There are no direct flights from the UK, so every trip involves one connection, most commonly through Lisbon. This page pulls together live fare data and route information to help you plan flights from London and other UK cities.
Best time to fly to Sao Tome and Principe
The climate is hot and humid all year, generally 26-30C. The main dry season, known locally as the gravana, runs from June to September and is the most comfortable time for hiking, boat trips and island-hopping, with a shorter drier spell around late December and January. October to November and March to April are the wettest months. Humpback whales pass the islands between roughly July and October, and marine turtles nest on southern beaches from around October to February.

Main gateway cities & airports
Nearly all visitors arrive at Sao Tome International Airport (TMS), only about 2km and a 5-10 minute drive from the capital. The smaller island has its own airstrip, Principe Airport (PCP), reached by a 35-minute inter-island flight from Sao Tome. There are no other international gateways, so Sao Tome is the single hub for the whole country.
Airlines and routes
TAP Air Portugal operates the key link between Europe and Sao Tome, flying several times a week from Lisbon. UK travellers usually fly London to Lisbon with TAP, British Airways or a low-cost airline, then connect onto the TAP service. TAP also serves Lisbon from Manchester, giving northern travellers a one-stop option. Regional carriers such as TAAG Angola Airlines connect Sao Tome with African hubs including Luanda, which can help if you are combining destinations. The Lisbon to Sao Tome leg takes around six and a half to seven hours; London to Lisbon is about two and a half hours, so allow a full travel day door to door.
Popular places to visit in Sao Tome and Principe

Top tips for finding cheap flights to Sao Tome and Principe
- Book both legs on one ticket through Lisbon where possible, so a missed connection is the airline's responsibility rather than yours.
- Travel in the shoulder weeks either side of the June-September dry season, when demand and fares often ease.
- Use the price charts on this page to compare months and set your dates around the cheapest departures.
- Be flexible on your UK departure airport, as feeding into Lisbon from Manchester or Gatwick can undercut Heathrow.
Travel essentials
Most UK passport holders need to arrange an entry visa online through the official Sao Tome e-visa portal before travelling; approval usually takes a few working days, and your passport should be valid for at least six months. Always check the latest FCDO advice before you book. The currency is the dobra (STN), which is pegged to the euro; euros are widely accepted and cash is essential as card payments are limited. Sao Tome keeps GMT all year, so there is no time difference from the UK in winter. Book the Lisbon connection as early as you can, as capacity is limited.
