I visited this WHS in June 2019 as a day trip from Lima. It would be an ideal stepping stone between Lima and Trujillo but I had decided against visiting the Northern WHS of Peru in favour of more time at the Galapagos islands.

In June the river is almost at its lowest levels and from Lima we crossed through the Supe valley right over the river's pebble basin without the use of a 4x4 vehicle. From Trujillo there now is an easier route which can accomodate coaches even though this WHS is quite off the beaten track with few visitors yearly.

Even though most of the site remains still unexcavated, with local and international archaeologists still on site during my visit, the pyramid structures were quite impressive and seem to have been built in harmony with the surrounding desert/mountain environment. Even though I haven't visited yet, at times it felt like Teotihuacan but with a surrounding environment not very different from the Nile in Egypt. The recently discovered reliefs as well as the rotten wooden structures still visible on-site hint at how these structures could have been in ancient times. Caral Supe is the biggest of several similar sites in the Supe valley and it is believed to be one of the most ancient sites of the Americas, even though another site being excavated in the Peruvian desert seems to be the oldest one discovered as of yet.

The guide gave us ample time to marvel at this ancient city and to take photos and we spent around 1.5hrs roughly with an extended tour. We got lucky as the garua and fog quickly dissipated as soon as we arrived and we could enjoy the beautiful site and its surrounding with plenty of sunshine. There is a very small makeshift visitor centre at the site with some statues and objects found at the site and a UNESCO WHS inscription plaque too. Make sure to bring cash with you as there were very interesting books for sale there. In a way it reminded me of the desert site of Gonur Tepe in Turkmenistan but thanks to the Panamerican Highway Caral-Supe is much easier to visit and is a treat for anyone interested in archaeology. It is practically still being excavated but from what I could already see, it looks very promising and could rival some of the better known ancient sites worldwide in a couple of years.
