Esperanza Base (, 'Hope Base') is a permanent, all-year-round Argentina research station in Hope Bay, Trinity Peninsula (in Graham Land on the Antarctic Peninsula). It is the only civilian settlement on the Antarctic mainland (the Villa Las Estrellas is on the South Shetland Islands). The base's motto is Permanencia, un acto de sacrificio ('Permanence, an act of sacrifice').
The LRA 36 Radio Nacional Arcángel San Gabriel radio station started transmitting in 1979 and currently broadcasts on 15476 kHz shortwave and 96.7 MHz FM. It is one of the southernmost radio stations in the world and its range signal includes audio identification in multiple languages. The host of "Panorama Nacional" Marcelo Ayala told at the beginning of 2024 about his life experience and broadcast by LRA36 Radio Nacional Arcángel San Gabriel.
A wind generator was installed in 2008, mounted by INVAP.
The 43 buildings of the station have a combined space of covered;Google Earth satellite images of fuel are used annually by the four generators to produce electricity for the station. Research projects include: glaciology, seismology, oceanography, coastal ecology, biology, geology, and limnology.
In the Hope Bay incident in 1952, this area was also the scene of the only shots fired in anger in Antarctica, when an Argentine shore party fired a machine gun over the heads of a Falkland Islands Dependencies Survey team unloading supplies from the John Biscoe to rebuild its damaged base. Following the Argentine show of force, the British team returned to the Falkland Islands. Shortly afterwards, Argentina issued a diplomatic apology, saying there had been a misunderstanding and the military commander on the ground had exceeded his authority. Despite this initial outward show of deference, the party was later welcomed back to Argentina with a hero's welcome. In the meantime, the John Biscoe had returned from the Falklands with a military escort and completed rebuilding the British base. The Antarctic Treaty of 1959 now treats the continent as a laboratory open to all, and provides that "no acts or activities ... shall constitute a basis for asserting, supporting or denying a claim to territorial sovereignty."

In winter, mean temperatures are around . A temperature of was recorded on 24 March 2015. This reading was the highest temperature ever recorded on mainland Antarctica and its surrounding islands, until on 6 February 2020, a new high of was recorded at the base, being the current record and considered by the World Meteorological Organization to be the highest temperature ever recorded for mainland Antarctica and its surrounding islands. The lowest temperature ever recorded is on 18 July 1994.
The temperature trend since 1948 is +0.0315 °C/yr (+0.0567 °F/yr) (annual), +0.0413 °C/yr (+0.0743 °F/yr) (winter) and +0.0300 °C/yr (+0.0540 °F/yr) (summer).
Historic site
A group of items or structures of historic significance at, or close to, the base have been designated a Historic Site or Monument (HSM 40), following a proposal by Argentina to the Antarctic Treaty Consultative Meeting. These comprise a bust of General San Martin, a grotto with a statue of the Virgin of Lujan, a flagpole erected in 1955, and a cemetery with a stele commemorating Argentine expedition members who died in the area.
General Martín Güemes Refuge
Refuge General Martín Güemes is the name given to two shelters in Antarctica. The first one is covered by ice, the second one is active. The refuge is Administered by the Argentine Army and depends on Esperanza Base, which is responsible for maintenance and care. The two refuges are located on the Tabarin Peninsula on the eastern tip of the Trinity Peninsula on the Antarctic Peninsula south of Esperanza. The refuges pay homage to Martín Miguel de Güemes, a military man who served an outstanding role in the Argentine war of independence.
General Martín Güemes I Refuge
The first refuge was located on the north east coast of the Duse Bay of the Trinity Peninsula and opened on October 23, 1953. , at that time head of the newly created Esperanza Base, participated in its construction, being one of the first refuges installed by the Army and the second in the continental Antarctica. The refuge was destroyed by the ice in 1960.
General Martín Güemes II Refuge
The second refuge is active and is located in the Tabarin Peninsula and was inaugurated on September 15, 1959. It has capacity for six people, food for a month, fuel, gas and a first aid kit.Refugio General Martín Güemes
