6th journey to the Indies (Java and Bali)
By the end of 1936, Nieuwenkamp, aged over 60 now, travelled to Java and Bali for the last time. The Adult Education Centre in Rotterdam had asked him to purchase some artefacts and create a Balinese calendar. He was given free passage to Batavia aboard the SS Kota Nopan owned by the Rotterdam Company Lloyd.
On arrival, he made a study of the Borobudur and the surrounding area and explored Bali once again. This time the journey was mostly done by car. On Bali he met many friends and celebrities, like Tjokorda Sukawati, Walter Spies, Beryl the Zoete and his friend and painter Rudolf Bonnet whom he travelled around with. He returned home in May 1937.
