19-Apr-2024: In 2023 it finally happened: we travelled in Australia and New Zealand for over 3 months. It was a great experience to see the Australian outback, kangeroos and koalas. New Zealand was great too, especially because Otto had the opportunity to visit his cousins. Have a look in our web album of 2023.

8-Oct-2022: Past Fall we made a trip in Oman. Using a 4x4 Nissan Patrol we travelled 4 weeks; desert, beach, mountains, wadis. Our photos can be found in our gallery.

Our climbing expeditions


Tilmans Pas expedition (2010)

In 1949 Bill Tilman explored the Langtang region in Nepal. One of the high passes in the area was named after him.

This remote 5300 m high pass is hardly used by trekkers. We crossed it as one of the very few (or even the only ones) in 2010.


Baruntse expedition (2009)

In Autumn 2009 we (and joined by Antonio) went to Nepal to try to climb Mt. Baruntse (7129 m).

Just as 5 years before Antonio managed to summit. Otto had to return and Marja joined him on the way back.

Later we also found time to explore Kathmandu and Pokhara.


Elbrus expedition (2005)

In 2005 we travelled to the Caucasian Mountains, on the border of Russia and Georgia, exactly between the Black and Caspian Sea. On the Russian side of that border is Elbrus, Europe's tallest mountain. We climbed the East Summit (5621 m).

To acclimatise we did a brief trekking near the mighty Bezengi Wall. And after the expedition we relaxed in Sochi at the Black Sea.


Aconcagua expedition (2004)

Our Aconcagua expedition took place in 2004. Together with Antonio Vicedomini we planned to climb America's tallest mountain (6962 m). 

The expedition was partly successful, Antonio summitted.

After the expedition we had ample time to explore places in Argentina, like the Iguazu Falls.

Travel blogs

During some of our trips we wrote a travel blog: South India (2019), Tilmans Pas Expedition (2010) and Baruntse Expedition (2009).


Summit list

So now and then we try to reach the high point of a country. We keep track of that in our summit list.

On the picture above we are on the 'summit' of The Netherlands, the Vaalserberg (322 m).



History of our family goes back to 1558. Albert was born in that year. He is our founding father. 

Hans Sluiter (1931-2021) did extensive research to our roots in the years around 2000. The results of his labor can be found on this web page.
