If you're looking for a unique part of the world few travel to, I can strongly recommend Paraguay. Was in country from April 19-May 3, 2022 and had an absolutely amazing time. Travelled over 2000 KM, including deep into the Chaco desert in the West as well as along the Parana River from Paso de Patria in the West to Encarnacion in the East. Was there primarily to study the sites of the Paraguayan War (1864-70) and Chaco War (1932-35).
Spent a day at the two UNESCO World Heritage sites--the Jesuit Missions (Reductions) of Jesus & Trinidad--and I was the ONLY tourist there! Wandered around with my guide in awe.
IF you buy goods and services off the Paraguayan economy, things are inexpensive. I exchanged currency downtown near my hotel at G6,830 to the dollar. A 750 ml bottle of Fortin Rum (Blanco) was just G17,000. The 8-year Fortin Rum (Negro) just G25,000. A 930 ml bottle of Ouro Fino beer just G6,000. The supposedly "better" 970 ml Munich bottle just G8,000.
Stayed 6 nights at the magnificent Palmaroga Hotel in the old town part of downtown Asuncion. Enjoyed the outside 12th floor pool on top; quite the view. Just loved walking around Asuncion from 0500-0700 in the morning as the city woke up. And then later in the morning when everything is open. Also spent 2 nights at the nice Hotel Florida in Filadelfia (one of the 3 modern Mennonite cities in the Chaco) and one night at the outstanding Hotel Papillion in Bella Vista (near the Reductions and the Selecta Yerba Factor tour). Even the Las Garzas in Pilar was a nice night's stay along the Paraguay River south of Asuncion.
Loved Paraguay so much that I'm planning on returning in March 2023 to see the natural wonder sites (e.g., Salto Cristal, the San Rafael Wildlife Reserve, Cerro Akati, and the Iguazu Falls & Itaipu Dam.
So easy to navigate the tiny Silvio Pettirossi International Airport. And so fascinating to hear Paraguayans speaking both Spanish and Guarani, the indigenous tongue that has survived alongside as an equal language. The only nation in S. America to do this.
