Make it absolutely necessary - Our guide was very entertaining and gave us a lot of information. The tour through the mangroves was great, we saw 3 different species of monkeys, various birds, crocodiles and during the night drive afterwards also very many fireflies. Recommended!

Amazing experience in Kota Kinabalu - 天気も良く、無事テングザルとホタルを見ることが出来ました！ガイドの方は親切で、とてもわかりやすい解説でした。施設は綺麗で、ローカルフードも美味しかったです。(特に揚げバナナ) 行きと帰りは2時間近くかかります。素晴らしいスピードで運転がなされますが、道路事情が良くないので、酔い止めは飲んで行って正解でした！ Amazing good experience in Kota Kinabalu. Fortunately we have seen some groups of proboscis monkeys and fireflies under the good weather. Fireflies were like stars in night sky. With kind and trustful guides, we have learned ecosystems of them. Facilities were clean. local food supplied there were delicious and sufficient. Consequently it is absolutely recommended.

Magical experience!! - Wow wow wow!!! Absolutely fantastic experience. We saw so many animals on our trip down the river during the day and thousands of fireflies on our evening trip. The food served during the day was delicious and our tour guide was so knowledgeable. Definitely a bucket list activity.

Magical!!! - This a must when you are in Sabah! Monkeys, fireflies and four hornbills flying over us at the end of the cruise. Both boat rides are fun, you can see everything clearly even without binoculars (but you can easily rent it). Dinner was fine. Although it was a long ride by bus it was absolutely worth it!

Tour objectives achieved! - I struggled with a wide range of tour prices, but I chose one with a lot of mouths and one with a middle amount. There was no doubt about the choice! The purpose of the tour was to see wild animals, so my friend didn't understand English, but he thought of a cospa and signed up for this tour. The tour Guides were gentle and pleasant, and our language was limited, but we were happy to discover them because they were easy to understand English, Tengu monkeys, which everyone wanted to see, were said in Japanese, and people around us responded when they found them. There was a lot of rain on the night of July, but I was very happy to see fireflies.

Lovely river cruise and great guides - Had a lovely time on this river cruise. Klias River is beautiful. On the first cruise, we saw baby crocodiles, macaque monkeys, and proboscis monkeys. The tour guides (Jamil and James) were lovely and happily answered all our questions about the river biodiversity. They also stopped at multiple locations along the river to ensure everyone got to see things. The guides get the boat all the way to the shore, so getting good photos is purely dependent on the monkeys!! The dinner was tasty and plentiful. The second cruise to see the fireflies was also great. We got to see so many! For anyone wondering about the journey, I experienced great communication about pick up from my hotel (Marilyn is on WhatsApp). The journey was 2 hrs each way in a minibus/van with excellent aircon. Overall, I would recommend this one! Thanks Only in Borneo Tours!

Great Klias River tour. - Except for the rain the whole experience was great and value for money. Excellent guide “Suliman” was both knowledgeable and entertaining. We got to see the proboscis monkey and lots of fireflies after rain showers which stopped.

Gorgeous fireflies - Saw a few proboscious monkeys but the fireflies are stunning. They were like lighting on a Christmas trees. So.e were attracted to our boat and stayed on our hands. Gorgeous. It is definitely woth seeing for city people like me who live in the concrete jungle. I joined on 22 Jun 2024 and our driver drove safely and was knowledgeable.

not really worthwhile - a long journey from town to location, two river trips, Sightings very limited, food provided was less than adequate. personally would not bother with this trip again.

Very short ride - Overall the tour was average. Pros : 1- The cruise is very quiet and smooth, since you are in a river there are no bumps. 2- The night cruise was actually good, watching all these fireflies filling up the trees, many of them. Also some may come to the boat, they are small and magical. 3- The staff is friendly. Cons : 1- After driving for two hours from Kota Kinabalu you expect that you are going deep in the river and its jungle but it’s actually a very short ride and you are able to see houses and the main road. The driver did not even go that far he just took a quick spin around the place and back in no time. 2- The monkey watching cruise (the first one) is nothing special, you barely see them as they are high up in the trees and they do not interact. Also the ones we saw were all young and small. We saw only one big monkey but it was hiding. 3- The dinner is not good as well, but there are some snacks you can buy.
