Contrary evidence
suitable for both beginner and advanced divers
Read source context
While some sources describe Deep Slope as suitable for 'advanced certifications' and 'experienced divers comfortable with depth and current', the description also states it is 'suitable for both beginner and advanced divers due to its varied depths, with some areas being shallow enough for introductory dives'. This creates an internal self-contradiction regarding the difficulty level.

Beginner to Advanced
Read source context
The refutation correctly identifies an internal self-contradiction regarding the difficulty level of Deep Slope. The description states it is 'suitable for both beginner and advanced divers' due to varied depths, while also noting some areas require more experience. This implies a range of difficulty rather than a single 'advanced' classification.

Maximum depthInformation under review
One source says both things. It reports this value and also contradicts it.
Contrary evidence
28
While the description states 'maximum depths that can exceed 30 meters', other sources indicate depths down to roughly 28 meters, 25 meters, or 30 meters. The claim of 40m as a maximum depth requires stronger direct evidence.

Read source context
The zone-level verified constraint for Malapascua Island states a verified temperature range of 24-30°C. However, several sources indicate that the water temperature in Malapascua can reach higher than 30°C, with some reporting averages between 28-30°C year-round, and others stating highs of 30.9°C or even 32°C during certain months.

32°C
The refutation is supported by multiple sources that indicate Malapascua's water temperature can exceed 30°C. One source states the water temperature holds at 28-30°C year-round, with highs up to 30.9°C in September and 32°C.

About This Dive Site
Deep Slope: varied terrain and macro-life reports
Sea Explorers describes Deep Slope in Malapascua as a combination of sand, rubble, reef and a small wall covered with soft corals. Its named account gives this dive a varied habitat profile rather than describing only a single reef face. The operator highlights a sand dune occupied by groups of garden eels and presents the site as an option for macro diving and underwater photography.
What the source reports
Alongside garden eels, Sea Explorers mentions flamboyant cuttlefish, frogfish, pygmy seahorses and nudibranchs around Deep Slope. These are reported subjects to discuss with a local guide, not a list of animals guaranteed on a dive. The account does not provide dated sightings, encounter frequencies or seasonal evidence. A descriptive animal name also does not establish a precise species identification for every report.
Route identity matters
This page covers the named Deep Slope dive. It does not equate Deep Slope with North Point, North Wall or another nearby route because a directory combines names. Ask the operator which terrain the planned dive will cover, whether it includes the dune or wall, and how the entry and exit are arranged. Those route details are not independently established here.
Depth and conditions remain incomplete
A reliable whole-site depth range is not established by the reviewed description. Depth figures for other named routes must not be transferred to this guide. Current strength, visibility and the conditions for your planned visit also require a current briefing. Use the habitat and wildlife account to compare the character of the dive, while confirming the depth plan and suitability for your training with the operator.
Two accounts of the sand-and-reef transition
Little Mermaid's Deep Slope entry lists a 15–23-metre profile, offering a source-specific comparison with the broader terrain description above. It is an operator listing, not an independently measured whole-site limit.
In her Malapascua account updated in September 2026, Annika Ziehen describes starting near an outcrop around 15 metres and exploring sandy rubble around 23 metres. A frogfish reportedly seen earlier was not found on her dive; she instead reports ghost pipefish, banded pipefish and seamoths. Keeping the unsuccessful search in the account matters: even a recent tip did not guarantee an encounter. She describes coral fields while ascending and an uncomfortable current, using a mooring line during the stop. These are observations from one visit, not proof of permanent mooring availability or a fixed current category. They add a concrete example of the habitat changes and variable conditions without establishing a prescribed depth plan or confirming that all operators follow the same route.
