Your best way to explore nature

Nature in colour is the name under which Institute Symbiosis organises exclusive wildlife holidays and nature tours in Slovenia. We are a local social enterprise, and a licensed tour operator, dedicated to nature conservation and education. By developing ecotourism, we seek to preserve nature and provide new business opportunities for rural communities. The guides on all our tours are specialised local naturalists, who take you to lesser-known areas and help you explore the diversity of animals and plants of Slovenia.

Why travel with us?

Small groups

To be able to offer the best nature experience, most of our tours are designed for small groups of 8 people or less. With larger groups, a second guide will be present. In the natural environment, we walk quietly and slowly, taking time to observe and photograph landscapes, plants and animals. 

Surrounded by nature

Slovenia is a small country, tucked between the Alps and the Adriatic Sea. It is this geographic position which gives the country’s flora and fauna a special dimension. Occupying only 0,004 % of the surface of the Earth, Slovenia is populated by 2 % of all land species. 

Expert guides

We specialise in nature guiding, we are biologists by profession and we have dedicated ourselves to nature conservation in Slovenia for more than 15 years. We will not only tell you which species you see, but also curious aspects of their behaviour and their roles in Slovenian folklore.

  • Thanks Paul! The nature excursion was indeed wonderful. The trip will stay fresh in my memory for a long long time. I will upload my pictures in a couple of weeks when I get back home!

    Custom butterfly trip 2017
  • Alweer ruim twee weken thuis, maar door het uitzoeken van en puzzelen met de foto’s ben ik keer op keer weer terug bij die prachtige acht dagen in dat mooie land. Bij de grote vuurvlinder had ik een verkeerde inschatting: – verwachtte een veel grotere vlinder – maar het was ook het moment dat ik té lang naar de zwarte ooievaar staarde, en het ‘moment suprême’ van waarnemen miste. Tsss… Ik blijf iedereen zeggen dat ik een TOP-vakantie heb beleefd!

  • Wij hebben hele mooie week gehad en heel veel mooie plekjes gezien en veel vlinders vogels en zelfs berin met 3 jonkies en hele mooie fotos kunnen maken. Jij deed het goed Paul Veenvliet, wij hebben genoten elke dag weer en goede accomodatie en lieve leuke gastvrouw en lekker eten dus zeer de moeite waard!
