Badian Island West

Also known as: Badian Island, Zaragosa, Zaragosa Island

A fringing reef off Badian Island south of Moalboal, inside a 9.7 hectare sanctuary the islanders have kept closed to fishing since 1987.

The dive

Two names, one island. Badian Island and Zaragosa Island are the same low island in Badian Bay, six kilometres down the coast from the Panagsama strip, and the diving is on the reef that fringes it. Coral grows branching and massive over rock, with sand between the heads. Above it a band of stone uncovers when the tide drops1.

The ride out takes ten to twenty minutes by outrigger, on the same circuit that reaches the coastal reefs either side of Moalboal. What happens once you are in the water is the guide's to set. Depth, route and turnaround are all decided in the briefing on this one, so listen to it and get the numbers before you gear up.

What makes it special

Fishing stopped here in 1987 and never restarted. The sanctuary covers about 9.7 hectares of the island's reef, a cooperative of island residents runs it, and the municipality pays an honorarium to a guard who lives in a guardhouse and watches the water1. Four decades of continuous local management is rare on a Philippine reef of this size, and it is the argument for making the trip.

It shows up in a count. When the reef was last surveyed, in 2013, the water inside the line held about 68 species per 500 square metres against 48 in the water immediately outside, and the species people fish for ran denser inside at roughly 137 per 500 square metres against 872.

The other difference is traffic. This reef is not on the daily rotation out of Panagsama and cannot be walked into, so the only boats that reach it are the ones that were asked to.

History and origin

The instrument is dated and numbered. Badian Municipal Ordinance 01-1987 closed the water, the sanctuary was set up under it by the Central Visayas Regional Project, and two later ordinances in 1989 and 2003 added to the protection1. Saavedra, on the Moalboal coast north of here, was declared in the same year2. In 1998 a presidential proclamation put the whole of the Tañon Strait under protection as a seascape, this water included, though that designation works at the scale of a strait and asks nothing of a diver.

On 6 February 2012 an earthquake of magnitude 6.7 hit the strait, its epicentre between this coast and Guihulngan on Negros. Water pulled off the shore and returned as waves that crushed through the reef walls, breaking coral and the pumpboats hauled up on the beaches2.

The reef has been counted five times, in 2005, 2006, 2007, 2010 and 2013. The deeper zone inside the sanctuary is the one that moved: live hard coral at 72 per cent in 2007, 44 in 2010, and about 36 in 2013, with bare substrate taking up the difference2. Then the record stops. Typhoon Odette crossed the Visayas in December 2021 and stripped the shallow coral on the Moalboal coast six kilometres north, and nobody has counted this reef since.

Know before you go

The fee you pay here is not Moalboal's. This island is in the municipality of Badian, its sanctuary was declared under Badian's ordinances, and the user fees that keep the reserve running go to the cooperative on the island1. No amount is posted in advance, so ask your shop what the fee is and who receives it. A Moalboal ticket buys Moalboal's water.

Then arrange it early. One shop on the strip takes the trip only with eight divers confirmed a week ahead and a permit arranged for the group, which turns this into a plan rather than a booking. The resort on the island has a dive desk of its own, and that is the other way in.

Help is a long way off, in a direction most people ignore until they need it. The chamber at Mandaue City is 82 kilometres from Panagsama and about two and a half hours by road, and all of that gets worse from Badian, which is further south again. Only three chambers were operational nationally in early 2025. Bring insurance that pays a hyperbaric bill, put the DAN Asia-Pacific line (+61 8 8212 9242) in your phone before the boat leaves, and confirm there is oxygen aboard.

Why Dive Badian Island West

What makes this dive site stand out.

  1. Sanctuary since 1987

    A 9.7 hectare area closed to fishing under a Badian municipal ordinance

  2. Run by the islanders

    A residents cooperative manages it and a guard lives on the island

  3. More species inside the line

    About 68 species per 500 square metres inside in 2013, against 48 outside

  4. Coral over rock and sand

    Fringing reef of branching and massive corals, with a rocky intertidal above

Summary

Nobody who runs the trip has graded it. Currents along this stretch are generally mild and set south to north, and the reef lies in a bay rather than on an exposed corner, but neither of those is a reading taken here. The real constraint is arranging it: one Moalboal shop takes the dive only as a permit trip with eight divers confirmed a week ahead.

Safety considerations

What can go wrong here, and what divers do about it. Conditions change - take the briefing from the operator on the day.

  • Remote location: The nearest recompression chamber is in Mandaue City, and Badian is further from it than Moalboal, whose own shops plan for 82 km and about two and a half hours by road.Cover that pays a hyperbaric bill, a conservative profile, and oxygen confirmed on the boat before it leaves.

Regulations

Marine reservePermit required

Zaragosa Fish Sanctuary

One Moalboal shop sells this only as a permit trip, eight divers minimum and confirmed a week ahead. That is a booking condition rather than a rule anyone has published, so ask what the permit covers and who issues it. The sanctuary's income is user fees, and the cooperative of island residents that manages the reserve is the body that collects them. No amount is posted in advance, so what you pay is what your shop bills on the day. Moalboal's environmental user's fee covers Moalboal's own municipal waters and this island is in Badian, whose rules for divers have not been established, so a Moalboal receipt cannot be assumed to carry here.

Frequently Asked Questions

Is Badian Island part of Moalboal?

No. The island lies in the municipality of Badian, the town immediately south, and forms part of barangay Zaragosa, which is why Zaragosa Island is its other name. Moalboal is where you book the boat and where it leaves from, and that is the whole of the connection. The practical consequence is about money and rules rather than geography: the sanctuary on the island was declared under Badian's own ordinances and is managed by a Badian cooperative, so Moalboal's environmental user's fee and its diving rules stop at Moalboal's municipal water. What you pay here is a Badian arrangement.

How deep is the dive at Badian Island West?

No depth for it has been published by anyone who takes divers there, and the figures circulating for this site come from crowd-sourced listings and from pages that generate their numbers rather than measure them. The reef has been surveyed, but at depths the method chose: snorkel transects at 2 to 3 metres and scuba transects at 7 to 8 metres. Those establish that reef exists at those depths, not where it stops. Ask for the maximum and the planned profile in the briefing, and treat that answer as the only one that describes the dive you are actually doing.

What does it cost to dive the Zaragosa sanctuary, and who collects the fee?

The sanctuary runs on user fees, and the body that collects and spends them is the Zaragosa-Badian Island Multipurpose Cooperative, an organisation of people who live on the island. The amount is not posted where a visitor can find it in advance, so the honest answer is that you pay what your shop bills you and should ask what the sanctuary's share of it is. Do not assume a Moalboal fee receipt covers this dive: different municipality, different body, different sanctuary.

How do you arrange a dive at Badian Island from Moalboal?

Early, and as a plan rather than a booking. One Moalboal shop takes the trip only as a special permit run with a minimum of eight divers, confirmed at least a week in advance. Another reaches the island on the same short outrigger circuit it uses for the coastal reefs, which is the quicker route in if the numbers work. The resort on the island has its own dive desk and its own boat. None of them runs the site daily, so it belongs at the start of a week of diving, not on the morning you fancy it.

What condition is the reef in now?

The last count is from April 2013. Live hard coral inside the sanctuary was about 48 per cent in the shallows and 36 per cent in the deeper zone, both rated fair, and the deeper figure had come down from 72 per cent in 2007 with bare substrate taking the difference. Part of that drop is attributed to the magnitude 6.7 earthquake of February 2012, which pushed the sea out and returned it in waves strong enough to break through reef walls along this coast, and to the typhoons at the end of that year. What has happened since is the open question. Typhoon Odette crossed the Visayas in December 2021 and stripped shallow coral at Moalboal six kilometres up the coast, and this reef has not been counted after it.

What will you see at Badian Island?

No species list for the dive has been published, so what can honestly be offered is the reef rather than a promise about animals. It is fringing coral over rock and sand, branching and massive growth rather than a wall of fans, and the counts inside the sanctuary in 2013 came to about 68 species per 500 square metres against 48 in the water just outside it, with fished species denser inside at roughly 137 per 500 square metres against 87. That difference is what four decades of protection buys. Dolphins and whale sharks come up in connection with Badian Bay, but nothing ties either to this reef and neither is a reason to come.
