The main settlement and "capital" is Georgetown where the tourist information office is in the Obsidian Hotel (see "Sleep" section).
This barren and uninhabited island was discovered and named by the Portuguese in 1501. The British garrisoned the island in 1815 to prevent a rescue of Napoleon from Saint Helena and it served as a provisioning station for the Royal Navy's West Africa Squadron on anti-slavery patrol. The island remained under Admiralty control until 1922, when it became a dependency of Saint Helena. During World War II, the UK permitted the US to construct Wideawake airfield on Ascension in support of trans-Atlantic flights to Africa and anti-submarine operations in the South Atlantic. In the 1960s the island became an important space tracking station for the US. In 1982, Ascension was an essential staging area for British forces during the Falklands War, and it remains a critical refuelling point in the air-bridge from the UK to the South Atlantic.
The climate on Ascension Island is subtropical. It is arid and lacking in vegetation until the elevation increases where lush forest and fertile soil exists.
The tourist information office is in the Obsidian Hotel (see Sleep).
All visitors must apply for an Entry Visa in advance (minimum 14 days before travel). An Entry Visa issued by the Administrator's office allows a stay of up to 3 months. Passports must be valid for a minimum period of 6 months from the date of entry into Ascension, and visitors must also have full medical insurance which will cover the expense of medical evacuation, if needed.
There is no public transport (including taxis) on Ascension. There are no hire cars available
Sport fishing is the main attraction for visitors to Ascension Island. There are also some beaches and ocean swimming in certain coves, such as Comfortless Cove and English Bay. Long Beach, as inviting as it looks, has a very hazardous undertow and is not suitable for sea bathing. However, it is a sheer delight for wildlife fans as this is where sea turtles go to nest. There are a few paths (such as Rupert's Path) suitable for hiking into the more lush highlands, as well as mountainside lava tubes to explore. The British pastime of letterboxing - hiking to a destination that contains a "letterbox" containing a log book and a rubber stamp pad - is possible here.
Ascension Island features what was at one time reputed to be the world's worst golf course. Located between the settlements of Two Boats village and Georgetown, the course has 18 holes and the greens are in fact 'browns', a reference to the sand and oil mix used to make them. The rest of the course is made up of volcanic ash and rock, which makes for some interesting rounds.
There is some terrific Scuba Diving in the waters surrounding Ascension Island. At present, however, there are only local enthusiasts and no recognized Diving Operation. Some of locals are often willing to take experienced visitors with them
There are Fumaroles and Lava Tunnels to explore (at Command Hill, near the Catholic Grotto)
The main shop is open 6 days a week and times are published outside the shop and in the Islander newsletter. Other businesses open at set times, and their opening hours are also published.
Because everything is imported prices for food are very high on the island. If you get the chance to go out fishing with the locals, you may walk away with a bag of tuna. Sometimes the community hosts a fish fry that is open to everyone.
There are very few places to eat, with odd opening hours
The only hotel on the island, operated by the Obsidian Group, has been closed since the 25th of September (same goes for it's 2 hostels and cottages), as Obsidian ceased operations following the last flights to the Island. Prices were the following: from £45 for a single to £79 for a VIP double. Hostel and cottage rates ranged from £25-£50 per night.
The same way you came in - by plane. The RMS Saint Helena ceased operations in 2018 after a new airport opened on Saint Helena.
There is limited mobile service on the island, but service may be spotty at best.  (Numbers starting with 0 or 5 have been reserved for future services).
The country code for Ascension is 247 and the population is too small to need area or trunk STD codes.
There is a Wi-Fi hotspot in Obsidian Hotel's lobby and patio for £10/day. The Post Office in Georgetown offers a vast array of Philatelic items for sale from the three islands of St Helena, Ascension Island and Tristan da Cunha. Airmail is possible, thanks to the airfield.
