I visited this WHS in Spring 2025. The big international car rental companies are now available near Davao airport. For the time being (till the airport enlargement works are completed), you are greeted upon arrival (excellent communication via email and whatsapp prior to arrival) and a shuttle takes you to the car rental office in Davao. This will make you waste at least 30 minutes to 1 hour in total as getting in and out of the city is slow with heavy traffic at most times of the day.

Since we were arriving quite late in Davao, we decided to visit the Philippine Eagle Sanctuary/Centre first (which is not part of the WHS but we wanted to support their invaluable work and make sure to see this magnificent bird). It is a good 1.5 hours drive to get there and 4 hours away from the Mount Hamiguitan Natural Heritage Museum or Visitor Centre. A good resort near the sanctuary is the Malagos Garden Resort with its own bird show (no Philippine Eagles here), butterfly garden, etc. and a must stopover point if you'd like to taste and buy the excellent Malagos chocolate.

Something to keep in mind when in Mindanao is that when it rains here, it really pours, as can be clearly seen with all the flood advisories along the roads. This is why we didn't want to risk it, so we drove to the visitor centre immediately after visiting the eagle centre and arrived after sunset. The roads overall were in very good condition and no 4x4 car is necessary in sunny weather. For the night we stayed at the Mount Hamiguitan Longhouse Lodge (which has its own UNESCO "plaque" at the reception although it is not in the core zone. Already at 408 metres above sea level, it is known as the "Jump Off Area" or simply the start off point from where permit holders start one of the 3 trails to the summit of Mount Hamiguitan. The Mount Hamiguitan Escape Resort was still closed during my visit, although a small bar selling local beer and Mt Hamiguitan corn brew coffee, as well as the pool, were open.

Just before the sharp turn leading to the Mount Hamiguitan Nature Heritage Museum, we spotted 2 UNESCO WHS information board type plaques, before reaching the parking lot with a proper UNESCO WHS plaque. The uppermost are of the mountain is frequently covered in clouds of mist and fog, especially in the morning, although we were lucky to spot the summit in the afternoon from Pujada Bay (proposed tWHS extension). Armed with binoculars and a zoom lens, I spent some time at the area with hairpins leading up to the museum, mostly to spot at least one of the 400 pairs of critically endangered Philippine eagles left in the wild (takes only one mate for life and lays only one egg every two years!). Although the area is designated as an Important Bird Area, it was more an exercise of bird spotting rather than proper birdwatching, which is why I'm still glad we made the effort to visit the eagle centre. We also spotted (impossible to take good photos) a pair of rufous-lored kingfishers (due to the proximity of a watershed), the unmistakable Mindanao bleeding heart, some cockatoos, Jerdon's baza, Philippine coucals, Philippine bulbuls, Mindanao hornbill, coletos, flowerpeckers, and a yellow-bellied whistler.

The Mount Hamiguitan Nature Heritage Museum and their helpful staff provide useful information to help appreciate this unique mountain range and some of the highlights it offers in terms of flora and fauna. Around the museum area, you'll definitely be able to see the endemic pitcher plants, orchids, lots of ferns, some pygmy trees and plants, butterflies, as well as lots of critters (orb weavers, giant ants, beetles, etc.). Obviously, we followed Thomas Buechler's instructions and reached the core zone after quite an uphill hike which took us less than an hour from our lodge, but if truth be told it didn't add much to our overall short visit, apart from feeling more fully immersed in nature with louder bird calls and non-stop insect activity (luckily no mosquitoes or leeches when we visited). In the upper floor of the museum/visitor centre, you'll also find the UNESCO WHS inscription certificate proudly displayed.

Mount Hamiguitan's summit is not that high at 1,628 metres above sea level. That said, after getting a permit individually or by joining others on a tour (taking place mostly on weekends), there are 3 trails to the summit which will take roughly 11 hours of uphill hiking over 2 nights (camping) and 3 days: the shortest but hardest being the La Union - San Isidro trail with some steep ravine climbing and the La Union river crossing involved, passing by Lantawan where large colonies of pitcher plants in varying sizes are observed; the easy to average Magum - Mati trail which offers many picturesque spots (Magum Lookout, Camp Jabar, Hidden Garden, Tinagong Dagat, Mossy Forest and Lantawan Magum) with a gradual ascent; and the average Domagooc - Governor Generoso trail which is the longest and follows the Domagooc river, passing by Domagooc Falls and Twin Falls before reaching Camp 3 at the Pygmy Forest. Most of these named places have a UNESCO WHS information board plaque of some sort.

Even if you don't reach the mountain's summit, the most important thing to observe and appreciate this site's OUV is definitely the presence of five vegetation types: brushland, dipterocarp forest, montane forest, mossy pygmy forest, and mossy forests. This shows the high variability of characteristics of the area, and despite the challenges brought about by certain environmental conditions such as ultramafic soil (igneous rock soil highly enriched in metals and depleted in plant nutrients).

The Bonsai Forest or Pygmy Forest is found at the topmost part of the mountain range and occupies approximately 1234.56 hectares (quite easy to remember from the museum's staff explanation) of the sanctuary. The stunted growth of trees (at an average height of 1.4 metres) could be attributed to the high concentration of cobalt, iron, nickel and magnesium in the soil. This ecosystem is a frontier for scientific research on the flora and fauna that thrive in such an environment.

Mount Hamiguitan hosts a whopping 957 recorded species of flora (ex. orchids, ferns, lichens, mosses, epiphytes, bryophytes, pygmy trees, pitcher plants) and 423 recorded species of fauna (ex. monkeys (long-tailed macaques and tarsiers), Philippine warty pig, monitor lizards, frogs, beetles (ex. Mystroceros rouyeri in photo), spiders, rodents (such as the endemic hairy-tailed rat), venomous snakes, stick insects, butterflies (we saw plenty of different and colourful species fluttering and mating when we visited), fireflies (easy to spot at night from the lodge), colonies of other critters (giant ants, bees, termites, etc.), birds (kingfishers, babblers, bulbuls, the Mindanao bleeding-heart dove, the Philippine cockatoo, the majestic Philippine eagles, hawk-eagles, eagle owls, etc.)). 6 flora (3 pitcher plants (such as the famous Nepenthes hamiguitanensis), 1 orchid, 1 hoya plant) and 6 fauna (4 butterflies, 1 rodent and 1 roundworm) species are now considered endemic to Mount Hamiguitan.

We really enjoyed our short visit to this natural WHS and after our visit we also covered the proposed extension of Pujada Bay which although quite ambitious (especially with the nearby fish farming practices) could truly extend this WHS so as to cover more vegetation types from below sea level to the mountain's summit.
