Oslob Whale Sharks

Oslob is a quiet coastal town in the far south of Cebu, and it is famous for one thing: swimming with whale sharks. Every morning, the biggest fish in the world come close to the shore at Tan-awan, just a few metres from the boats. Add a tall waterfall, a white sandbar island and old coral-stone ruins, and you have an easy and memorable trip from Cebu City.

Why go to Oslob

• Whale sharks up close, almost every morning of the year.
• Tumalog Falls, a tall, curtain-like waterfall a short ride away.
• Sumilon Island, with a white sandbar and clear water for snorkelling.
• Heritage: an old coral-stone church and the ruins of a Spanish-era barracks by the sea.

Whale shark watching at Tan-awan

The whale shark area is in Barangay Tan-awan, a few minutes north of Oslob town. You register at the visitor centre, listen to a short briefing and pay the fee, and a small boat takes you a few metres offshore. You can watch from the boat, snorkel at the surface or, with a dive shop, dive. The time in the water is short, usually around 30 minutes.

Watching opens early in the morning and closes around midday. Go as early as you can: the first groups get calmer water and fewer people. Fees are higher for foreign visitors than for Filipinos, and they can change, so check the current rates when you arrive.

Rules in the water

• Keep a distance of at least 4 metres from the whale sharks.
• Never touch, chase or ride a whale shark.
• No flash photography.
• Don't wear sunscreen or lotion in the water. It harms the sharks and the reef.
• Listen to your boat crew and stay close to your boat.

Good to know before you go

The whale sharks stay near Oslob because local boatmen feed them small shrimp every morning. This is why sightings are almost guaranteed, and it brings important income to the community. Marine researchers and conservation groups have raised concerns that daily feeding changes how the sharks behave and migrate, and that boats can injure them.

We want you to decide with all the facts. If you go, follow the rules above and choose an operator that respects them. If you prefer to see whale sharks feeding naturally in the wild, look at seasonal trips in places such as Donsol in Sorsogon or Southern Leyte, where the sharks are not fed.

Tumalog Falls

Tumalog Falls is a few minutes from the whale shark area. Water drips and pours down a high, mossy rock wall into a cool, shallow pool. The road down is steep, so most visitors ride a habal-habal (motorbike taxi) from the main road. A small entrance fee applies. It is a perfect stop after the whale sharks.

Sumilon Island

Sumilon Island is a small island off the coast, known for its shifting white sandbar and a protected marine sanctuary with good snorkelling. Boats leave from the Oslob coast for a short crossing. Part of the island belongs to a resort, so ask what is open to day visitors, and agree on the boat price before you go.

Oslob town and the Cuartel

In the town centre, visit the old Immaculate Concepcion Parish Church, built from coral stone, and the Cuartel next to it, the ruins of a Spanish-era barracks that was never finished. The seafront park is lovely at sunset, and the ruins are lit up at night.

How to get to Oslob from Cebu City

1. Go to the Cebu South Bus Terminal.
2. Take a bus heading to Oslob or Bato via Oslob. The ride takes about 3-4 hours, depending on traffic.
3. Tell the conductor where you are going, for example the whale shark area in Tan-awan or Oslob town, and get off there.

For whale sharks, leave Cebu City very early (around 4-5 am), or stay the night in Oslob so you are there when it opens. Many tours from Cebu City include hotel pick-up, the whale sharks and Tumalog Falls in one day. Oslob is also close to Santander at the southern tip of Cebu, where ferries cross to Negros for Dumaguete.

Where to stay

Stay near Tan-awan if the whale sharks are your main reason to come, so you can walk over in the morning. Oslob town has more food choices and is close to the church and the Cuartel. You will find simple guesthouses, homestays and a few resorts along the coast.

When to go

The whale sharks can be seen all year. The dry season, from about December to May, usually brings the calmest sea and the best visibility. Weekends and holidays are busiest, so try a weekday morning. From around June to November there is more rain, and rough weather can stop the boats.

Tips for a good trip

• Bring cash for fees, boats and habal-habal rides.
• Pack a rash guard for sun protection, since sunscreen is not allowed in the water.
• Bring a dry bag for your phone and a pair of water shoes.
• Go early, and combine the whale sharks with Tumalog Falls before lunch.
• Take your trash back with you and skip single-use plastic.
