Technically Osmena peak is inside the municipality of Badian, but it is often considered to be part of Mantalongon, Dalaguete because it is more accessible via Mantalongon.

Osmena peak is part of the Mantalungon mountain range, which is unique from other mountain ranges in the Philippines because of its multiple jagged hills grouped together that overlook and stretch as far as the Badian shorelines. The highest of these hills is the Osmeña Peak named in honor of the famous Osmeña clan in Cebu.

The visual appearance of the Mantalungon range is almost similar in form to the Chocolate Hills of Bohol but the peaks of the ranges are thinner, sharper-pointed and rocky. Unlike the Chocolate Hills, the peaks of the Mantalungon ranges cluster quite near each other and give the impression of being formed from rocks that have survived through time.

Once you reach the Osmeña Peak, you get a 360-degree view of that includes the southwestern coastline of Cebu, and you even see the province of Negros Oriental. However, the peak area is fenced and under private ownership. A lot keeper collects at least 20 pesos from each climber that enters the area and there is a campsite a few meters down the peak. The campsite has a toilet and a bunkhouse available to the public for a fee.

Osmeña Peak and the Mantalungon range are accessible to hikers and mountaineers all year round but it is best to climb the peak in the first half of the year since the rainy season is from June to October. The peak and mountain ranges become wet and slippery during the rainy season

Mantalungon is famous as the summer capital of Cebu because it is 700 to 800 meters above sea level giving it a pleasant climate all year round. The high elevation has made the village an ideal place to grow flowers, vegetables and other high-value crops, which gives Mantalungon the reputation of being the vegetable basket of Cebu.

Held every year is the Utanon Festival, a celebration of dance and music as thanksgiving for the good harvest of Mantalungon. Utanon is the Cebuano word for vegetables. Many locals and foreign tourists visit the village during summer because of its cool climate.
