Swimming with whale sharks in the Philippines

Animal attractions are a lot of fun and they make for good Instagram photos. Especially swimming with whale sharks. It’s in many tourists’ bucket list. How cool is it to actually swim with the biggest species of fish in the ocean?

Swimming with whale sharks is generally okay, as long as responsible practices are followed. But this isn’t always the case. In the Philippines, two areas are visited for its whale shark tourism. Oslob is the more popular one, but it’s also questionable ecologically speaking. On the other hand, Donsol is the better, ethical choice.

Whale sharks: Get to know them first

Whale sharks are known as the gentle giants. They are the largest fish in the sea, measuring up to 40 feet. They are plant-eating animals, hence the monicker.

They can be seen in a few places on earth, including Australia and select places in Asia. In the Philippines, whale sharks can be seen in Cebu, Sorsogon and even in Palawan. They are locally known as butanding.

Why you shouldn’t support the whale shark tourism in Oslob, Cebu

The whale sharks are a big tourist attraction in Oslob. It draws hundred thousands of tourists every year. People from all over the world flock to this corner in Cebu to swim and take pictures with them.

The locals regularly feed the whale sharks with krills to keep them in the area. This guarantees sighting all-year round.

There are various reasons this is not a responsible practice. One is that the animals suffer injuries from constant rubbing with boats and contact with tourists, despite a regulation that instructs everyone to keep a 4-meter distance from them.

People think that injury from human contact is only caused by irresponsible tourists, but this isn’t necessarily true. We were in Oslob about 2 years ago, and with the enclosed space as well as the whale sharks’ tendency to swim close or beside humans, it can be difficult not to hit or get hit by them. At least 3 in our group then experienced this. While this isolated cases might not be serious, taken collectively it may take a toll on the whale sharks’ bodies.

This leads me to the next item…

Whale sharks become accustomed to being human fed that they automatically associate human presence with food. This makes them easy bait for shark hunters or conditions them to come close to any boat, which is dangerous if the boats sport propellers.

The whale sharks are also not fed enough by the locals. Since the whale sharks miss out on the nutrients from various plankton growing in other areas, they suffer from lack of nutrition.

Lastly and perhaps the most important, this changes their migratory pattern. Normally, the whale sharks would stay in Oslob for about 2 months before moving to another place. With the regular feeding, they become mainstays in Oslob. Scientists fear that this may eventually harm their breeding cycle and thus reproduction.

Donsol, Sorsogon: Swimming with whale sharks the responsible way

The whale shark tourism in Donsol, Sorsogon, is a better alternative. It’s supported by the World WildLife Fund. Here, whale sharks are not fed by the locals.

It’s a seasonal activity following the animals’ natural migration pattern. Tourists are accompanied by spotters and guides to see the whale sharks in the wild. The best time to go in Donsol is from February to April.

As suggested by a fellow blogger, even during peak season interaction is not 100% guaranteed so it’s best to book for a whale shark tour for at least 2 days in Donsol Bay.

I’m not sure how the practice in Oslob affects that in Donsol. My close friend who lives in Sorsogon says that fewer whale sharks are being spotted in Donsol, possibly because many have preferred to stay in Oslob for the food. Another blogger wrote about the declining sightings of whale sharks in Donsol since 2011.

I think we’ll know for sure in a few years’ time, although I hope we wouldn’t have to get to that point.

Swimming with whale sharks in the Philippines

We were in Oslob before and found out about its implications only after our trip. Even today, not many people are aware of the effects of regular feeding to the whale sharks in Oslob and some of those who do are in denial.

In addition, people are divided on the issue of closing down the operation in Oslob, as it supports the local livelihood of about 300 people who work in the feeding site. Income is the primary reason the current practice in Oslob continues despite public pleas from researchers.

I would advise people to skip Oslob based on the facts given above. It’s basically a glorified underwater zoo. A lot of us feel bad about the maltreatment of animals in local zoos, but isn’t the same thing happening in Oslob? Furthermore, we can never really predict how it will affect the reproduction and survival of whale sharks or any ecological effect it may have in the future. Whale shark swimming in Donsol, Sorsogon, remains the ethical choice.

  1. Excellent information. We are heading to the Philippines in a few months and have been wary of which outfits we would use to see whale sharks due to the bad reputation and feeding practices that so many seem to have.

  2. I didn’t know about this until I read your post. Never thought that “Manila Zoo” is happening on an underwater level. I wish that they would not do the feeding part, and let the whalesharks be. There are always other means of income. And it’s not good if tourism will harm the environment sooner or later. Parang boracay lang. 🙁

  3. I wasn’t aware of the dangers to the whale sharks. It’s sad to know that this is happening and it’s being done to earn from. It should be put to law somehow how marine life is treated. It’d be sad to know that one day they become endangered.

  4. Thanks for sharing your experience. I just saw photos on Facebook of friends swimming with the whale sharks in the Philippines and thought it would be awesome. Now I know how not to do it.

  5. I was in Cebu and couldn’t justify on swimming with the whale sharks in Oslob (the environmentalist in me cringe…) but glad there is an alternative!

    Also, quick hello from FTB! I’ve been guilty of stalking your blog and found it really helpful for my trip to the Philippines!

    1. Thanks so much, Alyssa! 🙂

  6. Thanks for sharing this information, I think it will hopefully make a lot of people stop and consider their actions. I wouldn’t feel comfortable encouraging the feeding of wild animals for tourism, so I agree with you there!

  7. Oh, I have tried diving with the whale sharks in Oslob. That was 4 years ago. After reading this, I now feel guilty. I never gave it much thought, on what bad things that can happen to them. For me, as long as I see that they are swimming in open waters, I’m good. But now, thinking about it and after ready your post, everything I believed in has changed. Thanks for opening my eyes.

    1. Yeah, me too. We were there 2 years ago and before our trip we hadn’t read or heard anything about this issue. I think it’s really important to spread this info and educate others so we can have an informative choice on which attractions to visit.

  8. This is really the reason why I didn’t even try to go to Oslob and have a close encounter with whale shark. I don’t see any reason to do it because of the wrong way of treating them. I hope the Government of Oslob and Cebu will do something about this. This has long been an issue and yet the operation is still on-going even up to this time. I even fought with my friends regarding with this one, cause I tried to stop them to visit Oslob and swim whale shark. It is really heart breaking knowing that there are still people who don’t practice responsible tourism.

    1. People are divided and I think a lot are in denial because of the income it generates for Oslob. I’m actually surprised I’ve yet to see a disagreeing comment on this one.

  9. I can recommend the Whale shark nature foundation on leyte.
    We do this trip with Erhard from “whale shark divers” leyte . It is like roulette game . may be you got one – may be not 🙂 . But it is strictly observed by the foundation that not too much people go there . The spotters (which are fishermen before) get a new job there . They go with small boats and snorkeling glasses for looking if there are whale sharks present. If yes , the tourist boats which have to wait outside get informed and are allowed to come thru quiet and slowly . All snorkeling is observed from staff of the nature foundation . It was a great trip, because we are lucky and had 3 Whale sharks this day.

    1. Wow, thanks for the tip! I read about whale sharks in Leyte but there isn’t much info in the net then.

  10. I was in Cebu last March and I stayed in Oslob for 5 days but I didn’t partake in the whale shark activity. It’s not that I was being self-righteous but I simply do not support the practice.

  11. We have received offers and requests to cover the whale shark watching activity in Oslob several times. We turn them down every time because the practice is non-sustainable. It also affects their natural actions.

  12. I also agree that whale shark tourism in Oslob should be regulated if it is not possible to be prohibited. People should not always think of money they should also think of caring for nature because nature is our source of life. There are a lot of ways to help those people who depend on tourism in the place, earn a decent living.

    This makes me so sad. I think it’s so good that you tell us about the bad ways and the good ways of swimming with these giants. I think the people should always treat them well. Thank you for being an animal friend. That makes my heart happy.

  14. I am one with you in this cause. I do not recommend friends and acquaintances to visit Oslob with its whale shark related activities. Would recommend to visit its natural attractions like the Tumalog Falls and other structures. Plus according to my friends whom been there, the water is quite “malansa” and itchy, or better alternative is Moalboal’s Sardine Run.
