Orang-Utans & River Safari


About the Challenge

This wonderful trip offers a fabulous way to experience Borneo’s spectacular rainforest and wildlife, and to unwind after your trek!

Sepilok Orang-Utan Sanctuary is one of the highlights of any visit to Sabah. Surrounded by a 43km2 Forest Reserve, the centre was set up in 1964 and re-introduces rescued or orphaned orang-utans to the wild. The released apes often retain the habits they have learned at the centre and regularly come back to the feeding stations, giving us a wonderful opportunity to observe them.

We continue our wildlife discovery with a river safari on Kinabatangan River. Malaysia’s second-longest river, the Kinabatangan flows across Sabah; the lower Kinabatangan was designated a Wildlife Sanctuary in 2005. This protected eco-system is widely considered to be one of the best places to view wildlife in South-East Asia.

We cruise the waterways, exploring rainforest, ox-bow lakes and mangrove swamps, looking out for proboscis monkeys, orang-utans, gibbons, crocodiles and pygmy elephants, and birdlife such as hornbills and kingfishers. We stay for two nights in an eco-friendly river lodge, designed to blend in with its natural surroundings – a wonderful place to enjoy the serenity of the river and rainforest surroundings.

This trip is remote and fairly adventurous with some early starts to maximise wildlife-spotting, but there’s plenty of time to relax and watch the river go by!

Detailed Information

  • Your safety, and that of the rest of the group, is our highest priority. Our trips are designed and planned with safety in mind. Your crew will be equipped with communication devices (eg phones, radios and/or emergency satellite phones), medical kit and other safety apparatus appropriate to the destination. Our leaders always have access to our 24-hour emergency UK back-up. They are responsible for safety on the trip, and will make any changes to the itinerary they deem necessary, should local conditions dictate. Pre-trip administration - such as medical questionnaires and travel insurance as appropriate - is all done with your safety in mind.

Preparing for the Challenge

  • We plan our trips around the optimal weather conditions, but could still be exposed to bad weather at any time. It is vital you are prepared for all conditions. We provide you with a detailed packing kit-list on registration, as well as details on useful discounts you are entitled to as a Discover Adventure customer. We are always available if you need advice.

  • This is designed to be a challenge, and it is vital that you train sufficiently for it. We will supply you with a thorough training guide once you have registered. We expect all participants to train hard in advance, but we respect everyone’s limits and do not expect everyone to maintain the same pace. Inadequate training is likely to have an impact not just on your chances of completing the challenge, but enjoying it too - and we want you to have the time of your life!

    Our challenges attract people of all levels of experience, fitness and ability as well as all ages and backgrounds. We design our challenges so that everyone can go at their own pace: this is not a race. If you have concerns about your fitness or if you have reduced mobility please do contact us for a confidential chat about whether this challenge is appropriate for you.

    For logistical and safety reasons we sometimes need to re-group, so the front-runners may find themselves waiting for the slower ones. Please relax, and remember that this is a team effort that enables people to achieve their personal goals and earn sponsorship.
