Tumunong Hallu Beach, the Coastal Forest of Borneo

Whenever people talk about forest conservation, they would think that only the inland rainforest is worth protecting. Malaysian estate developers love to build condominium and resorts along seaside, as the sea view property is more marketable. As a result, there are very few pristine “beach forest” (coastal forest) left in Sabah, and most of us don’t know that the coastal forest of Borneo is also an important part of our forest ecology matrix.

Tumunong Hallu Conservation Area, which is along the coast of Darvel Bay, Lahad Datu (see location map), is one of the best examples of Borneo coastal forest and the first coastal conservation area. This 5.8-KM² fully protected forest is managed by Yayasan Sabah Foundation for research and education purposes. They consider opening the area for tourism too in future, as the beautiful beaches there are suitable for recreational activities. For now, it is a hidden treasure.


Thanks to Bike and Tours, I learnt about Tumunong Hallu last year. Tumunong Hallu is about 20 KM from Lahad Datu town and accessible by road, but we go by boat so we could cruise around the islands of Darvel Bay. We saw mangrove forest, water villages, fish farms and fishing platform on the way.


Then a marine police patrol approached our boat. I sweated a bit because I thought we entered the restricted area.


Well, it happens that they know our boatman and would like him to help sending something to Tumunong Hallu, phew…


I also saw a lot of fishermen and fishing structure named Selambau (see photo below). Seem like everyone lives in Darvel Bay fish for a living.

The Beach of Tumunong Hallu

After an hour, we arrived the beach of Tumunong Hallu.

Since you can view the following photos, I don’t need to write too much to describe how inviting and tranquil the sea water is…

The seabed is rocky with layer of smooth silt, and the beach is covered by dark sand, all these are the characteristics of forested beach.

Besides the land, Tumunong Hallu also includes the sea area with rich marine biodiversity such as coral reef, and two nearby islands, i.e. Saranga and Tabun Islands, into its 1,600-Hectare conservation area.

Hiking

The researches show that Tumunong Hallu has 81 plant species comprising coastal and inland vegetation. The best way to explore the interesting mixture of mangrove and dipterocarp forest here is by jungle trekking.

We tried the shorter nature trail that is only 3 KM one way (then taking a boat back to starting point). If you have more time, you can hike the longer trail to the hilltop, which takes 4 to 5 hours, to have a nice view of the beach and forest.

Two forestry rangers, Yapdi and Azwan, were accompanying us and share some interesting facts about this forest. The trail is easy to walk and the jungle is not warm and humid as the rainforest, due to the sea breeze.


The soil here is quite fertile, evidenced by a big earthworm I found on forest floor.


Pic: we took a short climb to Ara Viewpoint, which is a knoll near to a beach.

There was strong scent of Kayu Malam tree in the air of this slope. This wood is a famous aphrodisiac among local ladies if I’m not mistaken.

We also checked out the Nunuk Beach not far away.

The coastal forest is not just a collection of dull trees. Among mangrove, seaside hill and beach forests, there are some interesting and unique trees, such as the Keruing tree below.


Pic: this Keruing tree looks like being vandalized. Actually the “cut” is a natural feature of its bark.


Pic: the tree in the coastal forest can be big and tall too, like the Nunuk Tree shown in photo above.


Pic: beautiful white stripes on the bark of Nunuk Tree.

If there are trees, there must be wildlife. I didn’t see a lot of wildlife, but studies say some birds (e.g. Great slaty woodpecker) and mammals (Long-tailed Macaque, Barking deer, Sambar deer) are the residents of this forest. We were hungry after one hour of hiking, so we took a boat back to the starting point for lunch.

Amenities at Tumunong Hallu

As this beach is not frequented by tourists, the facilities are basic but good enough for camping. There is no resort, restaurant and shop here. If you want to cook, you have to bring your own cooking utensils and gas stove.

Pic: Yummy Indian food prepared by Tisha and Simon from Bike and Tours, the curry and sour vegetables were so appetizing… They really know how to cook and present the food. This friendly couple receives a lot of positive feedbacks at TripAdvisor.


Hey, we were at the beach so we must soak ourselves in warm tropical sea water to conclude the tour. The whole beach was ours to enjoy. Overall, it’s a wonderful experience.

Even though Tumunong Hallu is not a popular destination now, being unfamous doesn’t mean that it has no potential. If it is open to public in future, you must visit this place. At the moment, you can arrange a tour with Bike and Tours for a trip to Tumunong Hallu.
