Confession – it took us about three days to work out how currency (peso) operates in Argentina. It started with us getting about 190 pesos to the pound when we took cash out of an ATM. Our Buenos Aries guide explained that we were doing it wrong and that she would provide us with cash for dollars or euros (not pounds) at a rate that equated to 350 pesos. This is known as the “blue market” (sounded black to us), the reason being that Argentina has 100% inflation and no foreign currency reserves so everyone wants hard currency. The cash she provided was accepted without any questions and “blue” seemed a commonly used term.

So far so good, but we then realised that there was a further twist to the story when paying on a debit card in shops and restaurants. The transaction went through at the official rate, but two or three days later we received a rebate from our bank representing approximately 40% of the transcation value. We discovered that late in 2022, the government introduced the MEP dollar rate for foreign debit and credit cards in an attempt to defeat the cash based blue market while encouraging foreign currency spend by tourists. The MEP rate is fixed at about 95% of the blue rate. This is further complicated by different arrangments with different credit/debit card companies. Our rebates were from mastercard, however VISA uses the MEP rate for the originating transcation and it appears that AMEX use the official rate with no refund.

Meat is the staple diet in South America; in Patagonia lamb and in Northern Argentina, beef. We were told that Uruguayans eat 85kg of beef per year and suffer the consequential health issues. After our excellent barbeque in Misiones and an outstanding steak in a Buenos Aries restaurant, we decided to have a vegetarian night out. Our hotel recommended a nearby restaurant, Marti. This turned out to be one of the best but most unusual dinner experiences we can remember.

Entering via a side door resembling a goods entrance, we walked down a dingy corridor, through a trendy ladies boutique and through a “door” similar to the entrance to a cold storage facility; all while listening to nightclub style music. Following this arrival, we found ourselves in a swish glass walled restaurant with modern counter seating surrounding an open kitchen. The vegetarian menu was innovative and delicious with a focus on mushrooms which were grown on site.

The El Ateneo bookshop is the former Theatre Grand Splendid, which opened in 1919 and was converted into a bookshop in 2000. Over a million people visit each year to browse, buy books and use the cafe which used to be the stage. In 2019 National Geographic named it as the “world’s most beautiful bookstore”. By coincidence, we visted on World Book Day.

Buenos Aries, is situated on the western bank of the River Plate. It was first established by the Spanish in 1536. Argentina was declared independent in 1816 under the leadership of San Martin, however Buenos Aires was still under threat from an Anglo-French blockade as late as 1848. The blockade, driven by an objection to local taxes, failed and the city flourished. Around a third of the country’s 45million citizens live in Greater Buenos Aries.

Much of the city’s architecture shows European influence (particularly Spanish and French) from the waves of European immigration, particularly from France, Spain and Italy. Although the British were less prominent, they were responsible for establishing the railways.

The falls is situated in the south of the Atlantic rainforest. Most people visit solely to see the falls. However we were able to do two forest hikes, followed by a barbeque. We were accompanied by our guide, Cami, and Toto. Toto is an ex-military, part-time ranger, member of the local search and rescue team, snake expert, path clearer, driver and and grill chef. The path we took was not in regular use and the rainforest grows very quickly – without Toto’s expertise and machete our route would have been impossible.

The Iguazu Falls are the largest falls system in the world with 275 drops over almost 3km. The longest drop is the Devil’s Throat at over 80 m. The guides say that although the majority of the falls are in Argentina, the best views are from the Brazilian side, so we visited both sides. On the day, the waterflow was slightly above average at 1.7 million litres per second (an Olympic swimming pool holds 2.5 million litres).

Both sides have extensive trails, along, under and behind the falls. Part of the Argentinian trail was closed due to a storm in October 2022 which created waterflow of 14.5 million litres per second and washed away the boardwalk.

A long day with three internal flights took us from Patagonia to the province of Misiones, in north east Argentina, for a late arrival at our new hotel and our “cabin” in the rainforest.

The highlight of our first day, despite torrential rain, was a boat trip to the junction of the River Iguazu and the River Parana where Argentina, Brazil and Paraguay meet. This is one of 175 tri-points in the world; there are no instances of more than three points meeting but this has been the subject of some debate as there are borders where more then three countries meet within close proximity.

The River Parana is the second longest in South America after the Amazon and is the subject of tensions with Brazil as the flow is controlled by a dam 9km north of the border.
