Greetings, I am planning a (likely solo) gap year type backpacking trip to South-East Asian countries (anywhere from Myanmar to Indonesia - perhaps a trip not too dissimilar to @Chlidonias or @LaughingDove 's adventures) in 2022 for a few months. The likelihood of its' occurence depends on the COVID situation, however I thought it was worth planning nonetheless. The trip will entail volunteering in addition to general travel. What are the best places for zoos, wildlife, nature and sightseeing in this region? I am aiming to see zoos, mammals and birds (mainly mammals, perhaps meaning spotlight friendly regions should be favored?) although am not sure which regions would be the most accessible/buget friendly/worth visiting/dense in the desired sectors. So far I have thought of Bornean Malaysia (Sarawak mostly) and Singapore as ideal locations - having lived in Borneo I know of these areas well but have not explored their wildlife/zoo potential. Would Indonesia be worth visiting? Sumatra has good volunteering opportunities but are there desired locations/zoos/wildlife that would make additional travel worthy? Also are countries such as Vietnam and Cambodia still worth visiting even though the potential of seeing mammals is lower than in other areas such as Borneo. I understand that the virus will inevitably dictate the plan, however I am open to and would be very thankful for recommendations of regions/itineraries/advice.
