Diving Siquijor & Apo Island — Where the Turtles Are

Siquijor's 30+ Dive Sites

Siquijor has roughly 30 mapped dive sites in its surrounding waters, ranging from beginner-friendly coral gardens to advanced drift dives. The best sites are clustered in two protected marine sanctuaries: Tubod (southwest) and Tulapos (east), both home to healthy coral and abundant marine life.

Tubod Marine Sanctuary (Southwest)

Depth: 5–30 meters. Marine life: coral-dwelling fish, nudibranches, sea snakes, cuttlefish, ghost pipefish, sea turtles. The reef has multiple entry points suited to different skill levels. Shallow coral gardens (5–15m) are ideal for open-water divers; deeper sections (20–30m) host larger pelagic fish.

Why dive it: Year-round protection means healthy coral and dense fish populations. Early morning dives (6–8 AM) offer the best visibility and calmest seas.

Tulapos Marine Sanctuary (East)

Established in 1986 — Siquijor's oldest marine reserve. Depth: 8–40 meters. Famous for: seasonal barracuda runs (December–March), cave systems, coral crevices. Marine life: barracudas, jackfish, blacktip reef sharks (small, non-aggressive), sea turtles, groupers.

Why dive it: More adventurous than Tubod. The cave systems and barracuda encounters make it memorable. Best for intermediate+ divers. Peak season: December–February when barracuda congregate.

Other Notable Sites

Apo Island Day Trip: World-Class Diving

Apo Island is a 30-minute boat ride from Siquijor's main port. It's one of the world's top 10 dive sites and absolutely worth a day trip. The site is a marine sanctuary with strict protection rules and astounding biodiversity.

What Makes Apo Special

Typical Apo Day Trip

Schedule: Pickup 6:30 AM → Boat to Apo (30 min) → First dive 8 AM → Surface interval + lunch (on boat, pre-packed) → Second dive 11:30 AM → Return 1:30 PM → Arrive Siquijor 2 PM.

Cost: ₱3,000–3,500 for a two-tank dive with lunch included. Equipment rental is extra (₱500–1,000 if needed).

Booking Apo Dives

Book through your dive operator at least 1 day in advance. All operators offer Apo day trips. Weather can delay departures (Apo is exposed to rough seas during monsoon), so be flexible on timing. Best weather months: November–April.

Warning

Apo is a working marine sanctuary. No touching coral, no collecting shells, no feeding fish. Violators can be fined heavily. Respect the reserve — it's why it's so pristine.

What to Ask Before Booking

Costs Breakdown

Service Cost Range Notes
Single Dive ₱2,500–3,500 Includes boat, guide, tanks, weights
Two Dives (same day) ₱4,500–6,500 Most operators offer discounts for multiple dives
Apo Island Day Trip (2 dives) ₱3,000–3,500 Includes lunch, longer boat ride
Equipment Rental ₱500–1,500 Full set: BCD, regulator, tank, fins, mask
PADI Open Water Cert ₱12,000–15,000 3 days, classroom + confined water + open water dives
PADI Advanced Open Water ₱8,000–10,000 2 days, 4 specialty dives

Best Diving Season

Optimal: November–April

Why: Northeast monsoon brings calm seas, good visibility (15–25m), and lower boat cancellations. December–February are peak months for barracuda runs at Tulapos and turtle encounters.

Possible: May–October

Visibility: Fair (10–15m). Conditions: Rougher seas, higher chance of boat cancellations. Upside: Fewer divers, lower prices, interesting seasonal fish movements.

To Avoid: June–August

Southwest monsoon brings choppy seas, frequent rain squalls, and poor visibility. Many operators reduce schedules. Not ideal unless you're flexible on cancellations.

Certification & Requirements

PADI Open Water (Beginner)

No prior experience required. 3-day course: 1 day theory + confined water training in pool or shallow water, then 2 days open water dives (4 dives total). Cost: ₱12,000–15,000. After certification, you can dive to 18 meters independently (with a buddy).

For Non-Certified Divers

Most operators offer "Discover Scuba" taster dives (₱2,500–3,000). A guide conducts a brief training session, then takes you on a shallow dive (max 12m). Good way to test if diving is for you before committing to full certification.

Logged Dives & Recency

If you haven't dived in 6+ months, most reputable operators require a "refresher dive" before proceeding to new sites. It's a safety rule. Cost: ₱2,500 (counts as a regular dive but on easier site).

🤿

Get Certified Before You Go

If you're not PADI certified, consider doing your Open Water course at home first. Certification in Siquijor is perfectly valid, but doing it before you arrive gives you more flexibility to dive immediately and explore multiple sites.
