"This tour is a celebration of the dynamic work of nineteenth century explorer Alfred Wallace, who played a major role in Darwin’s thinking about the evolution and development of our planet."


Wallace observed a line of ecological demarcation between the islands of Bali and Lombok, an evolutionary masterpiece! Here you will be able to experience first-hand the wonders of this evolutionary process in nature.

This is also an exciting wildlife tour, where you will see critically endangered species in their natural habitat. Many of these species are endemic to the area and offers uniquely special experiences for animal and bird lovers alike.

Australasia to the East
Asia to the West

This is where the magic lies! The Wallace Line is an imaginary boundary that runs between the islands of Bali and Lombok dividing two unique ecosystems. To the East, on these eco tours you will see species of Australasian descent and to the West, species that are similar to the Asian mainland, and some species are a hybrid of the two.

The effect is also seen to a lesser extent in the flora of the area and even the landscape is distinct on either side of the line. But for animal enthusiasts, The Wallace Line is one of the wonders of the natural world.

To the West you will discover the wet tropics, with its unique rainforests and endangered primates such as Orangutans, Proboscis Monkeys, Gibbons and Langurs among nine species in the Tandjung Puting National Park. Here you will be treated to the “Rimba Experience” which has been described by many as “The Best Wild Orangutan Experience in the World”.

Then, you will spend time exploring the dry tropics to the East, with the prehistoric giants of the lizard world: the Komodo Dragons.

These ferocious creatures can only be found here in the Komodo islands, west of Labuan Bajo. You will also experience fabulous reefs full of Corals, Sponges and Fish of great biodiversity that make up part of the “Coral Triangle”, recognized as one of the best snorkelling and diving areas of the world.


Our eco tours are private and as such, perfectly flexible. They can be customised to your needs, interests and schedule. You may wish to spend more time in some places and less in others, do more or less hiking or include different experiences that are not in the suggested itinerary.

We welcome the chance to plan your Wallace Line Ecological tour with you.

Lunch is taken on the boat before walking around two km to the feeding station.

Camp Leakey (named after Oxford based scientist Louis Leakey), is one of the homes of Professor Birute Galdikas. Camp Leakey is known as the longest biological, documented, scientific experiment on the globe. Birute Galdikas is one of Leakey’s golden angels, the others being Dianne Fossey (Gorilla scientist) and Jane Goodall (the Chimpanzee scientist).

Oragutan Tours

The Orangutan is a close relative of humans and have shown an ability to learn signs as a method for communicating with humans.

On the cruise home, if the evening is clear, you may enjoy a stunning river sunset with Proboscis Monkeys.

You will arrive at the large Island of Rinca around 09:00 depending on currents and will proceed by foot to look for the giants of the lizard world, the Komodo Dragons.

The Komodo Dragons are a seriously endangered species, that grow up to 3.5 metres in length. They have a ferocious bite combining serrated teeth with a mysteriously toxic saliva.

Here you should also see a number of bird species and hopefully buffalo and deer. Lunch will be served back on the boat before more opportunities for snorkelling. This is a fantastic area renowned for its biodiversity.

DAY 9 - Hiking and Birding

One cannot compare the two ecological systems in Indonesia without looking at some of the birds, and this day of hiking and birding will be led by Sam Rabenak, a specialist bird guide.

For those interested in waterfalls, this can be arranged as part of the day too. The Mbeliling mountain area is a vital water source for Labuan Bajo and this area has some endemic species of both birds and trees.
