Visas & entry
Entry rules are separate for all three islands: St Helena visitors generally need to meet entry/visa requirements; Ascension requires an entry permit before travel; Tristan requires advance permission from the Tristan authorities as well as a confirmed ship berth. Do not rely on UK visa rules—verify requirements directly with the relevant island administration before committing to flights or vessels.
Getting in
- Johannesburg, South Africa: The practical year-round air gateway for St Helena, normally via the weekly Airlink service to St Helena Airport. This is the sensible routing for a St Helena-only trip.
- Cape Town, South Africa: Cape Town has seasonal St Helena flights around the southern summer and is the essential staging point for Tristan da Cunha. Tristan has no airport: visitors sail from Cape Town, usually taking about six days each way.
- St Helena Airport, St Helena: The operational gateway for the infrequent St Helena–Ascension charter. Ascension is not a casual add-on: secure its entry permit and flight seat before treating it as part of a St Helena itinerary.
- Ascension Island / Wideawake Airfield: Arrivals are tightly controlled and depend on the limited service and an approved permit. Visitor seats are scarce and can be subordinate to official and employer travel.
Getting around
There is no useful inter-island transport network: St Helena, Ascension and Tristan are three separate expeditions, not an island-hopping circuit. On St Helena, hire a car is the realistic way to reach walks, rural districts and the east; distances are short but roads are steep, narrow and slow. Ascension also rewards a vehicle or pre-arranged transport, while Tristan is walked, locally guided and governed by weather; getting there and leaving is by ship, not domestic flight.
Money
St Helena uses the St Helena pound, pegged 1:1 to sterling; GBP is accepted. Ascension and Tristan operate effectively in sterling. Carry cash and do not assume cards will work everywhere or that ATMs, change and payment connectivity will be reliable; these are supply-constrained islands, where transport and accommodation—not meals—usually break the budget.
Daily budget · SHP is pegged 1:1 to GBP on St Helena; GBP/sterling is the practical visitor currency on Ascension and Tristan da Cunha.
- Value
- St Helena: £120–180 value; Ascension: £170–250 value; Tristan da Cunha (ashore only): £110–180 value.
- Mid-range
- St Helena: £220–350; Ascension: £280–450; Tristan da Cunha (ashore only): £180–300.
- High-end
- St Helena: £400–650+; Ascension and Tristan have no genuine luxury tier, only pricier scarce accommodation and private arrangements.
- Bands are per person per day, generally assuming shared rooms, and exclude international flights to southern Africa.
- St Helena is the only place where a conventional independent budget works. Car hire, whale-shark trips, diving and guided marine outings move the total sharply; cars are often unavailable at short notice from November to April.
- Ascension is expensive because everything is scarce and supplied remotely; food is estimated at roughly 30% above UK prices. The St Helena–Ascension return flight is a major separate cost (published at £890) and a seat matters more than the headline fare.
- Tristan’s daily ashore figure is misleadingly incomplete: the Cape Town ship passage, long waiting periods, possible schedule changes and extra Cape Town buffer nights are the real budget risk. Build a large contingency rather than trying to economize on-island.
- Across all three, the expensive part is access and inflexibility, not luxury consumption. Book transport first, then price accommodation, vehicles and wildlife activities around the confirmed dates.
Eating well
- On St Helena, do not leave dinner to chance outside Jamestown: book ahead where possible and confirm opening days directly.
- Use St Helena’s self-catering shops and guesthouse kitchens as a backup, especially if staying in rural areas where evening options are thin.
- On Ascension, bring expectations down to functional: accommodation and food arrangements should be confirmed with your host before arrival, and imported goods can be expensive or temporarily unavailable.
- Do not expect to eat green turtle on Ascension; nesting beaches and turtles are protected, and turtle viewing should be through official conservation tours.
- On Tristan, food is part of living within a very small community, not a consumer experience. Accept limited choice, ask before relying on any café or bar opening, and carry contingency snacks for weather-disrupted days.
- If you have dietary requirements, state them while arranging accommodation and transport—not on arrival. All three islands have constrained supply chains, with Tristan the least forgiving.
Book before you land
- Book St Helena accommodation and a hire car before buying non-refundable peak-season flights; cars can disappear entirely from November to April.
- On St Helena, build weather slack into the itinerary. Highland cloud, wind and sea conditions can cancel hikes, diving and whale-shark trips even when Jamestown looks fine.
- Ascension requires advance permission; do not book a St Helena–Ascension itinerary on the assumption that visitor flight seats will materialise later.
- On Ascension turtle beaches, use only authorised tours at night: lights, flash photography and casual wandering can disturb nesting turtles.
- For Tristan, keep flexible flights on both sides of the voyage and budget for weeks of disruption. Vessel schedules, landings and return dates are provisional, and passengers can be displaced.
- Tristan is a tiny working community, not a staged heritage village. Ask before photographing people or private property, respect local schedules, and arrive self-sufficient rather than expecting broad dining, shopping or medical services.
Entry rules change — verify visa requirements for your passport before booking this country.
Season by season
December–March
St Helena is warm and busiest, with whale sharks usually present from November into April and strongest odds in January–February; Ascension is hot, wetter from January and in peak turtle season; Tristan has its longest days and comparatively mildest, least-wet weather, though wind and cancelled landings remain normal.
Seasonal Cape Town flights make St Helena easier to reach but intensify demand for rooms, hire cars and operators; Ascension remains permit- and seat-limited, while Tristan shipping can still change without warning.
April–May
St Helena is quieter after the festive and main whale-shark peak, with generally tolerable walking temperatures; Ascension turtle nesting continues; Tristan turns cooler and wetter as autumn sets in.
Whale-shark chances are less dependable than in mid-summer, St Helena cruise calls can briefly crowd Jamestown, and Tristan timing is dictated by vessels rather than pleasant weather.
June–September
St Helena is cooler, with rain and cloud especially common in the central highlands from July to September; Ascension is relatively drier but still hot in the lowlands, while Tristan has short days, frequent gales and wet weather, with snow often on high ground from July to September.
Carry rain and wind layers for St Helena rather than expecting tropical weather; Ascension turtle nesting is ending after June, and this is the worst weather window for a first Tristan attempt.
October–November
St Helena often has pleasant conditions for walking, heritage and diving before the hottest months, while cruise calls resume; Tristan is in spring, with improving daylight but unstable seas and weather still capable of disrupting landings.
It is early for St Helena’s most reliable whale-shark encounters, cruise days can make Jamestown temporarily busy, and Tristan remains governed by shipping and sea conditions rather than a fixed itinerary.
Events worth planning around
Festival of Lights and Christmas period · December; exact programming varies year to year. · St Helena, especially Jamestown
This is a high-demand period for accommodation, car hire and dining; reserve early if travelling over Christmas.
Easter fishing and camping traditions · Easter; dates vary annually. · St Helena
Local activity increases and limited services can be tighter; check the current island calendar before fixing dates.
St Helena Day · 21 May · St Helena
The island’s mood and local programming change noticeably, and small-scale accommodation and transport availability may tighten.
Walking and running festivals · Occasional; some are biennial or vary by year. · St Helena
These can fill beds, cars and guides disproportionately; confirm dates locally before building a trip around one.
What to eat
Eat for the logistics, not for a restaurant scene: choice is narrow, supplies are imported, and opening hours can be irregular. St Helena has the broadest range, built around local fish, coffee and homestyle dishes; Ascension and Tristan reward advance planning, self-catering where possible, and flexibility when weather or shipping affects supply.
St Helena: St Helena coffee · Tungi prickly-pear spirit · Fresh tuna, wahoo and other local fish · Fish cakes and casual homestyle cooking
Ascension: Freshly caught fish, particularly tuna when landings permit · Simple provision-led meals rather than a distinctive restaurant cuisine
Tristan da Cunha: Tristan rock lobster · Potatoes from the Potato Patches · Local fish and limited, practical community cooking
