To go to the Blue Hole Depths in Dave the Diver , dive down past the Medium Depth and keep heading right-side routes when they appear; the area starts around 130m deep and opens up toward 250m. The Blue Hole Depths also cannot be entered during night diving because it is too dark to navigate there safely.

What to do

  1. Progress the main story until the game unlocks deeper sections of the Blue Hole.
  2. During a daytime dive, descend to about 130m or deeper.
  3. Look for the transition into the Blue Hole Depths, which is usually on the right side of the Blue Hole.
  1. Bring better diving gear, since oxygen drains faster and enemies get tougher down there.
  1. Expect the route to lead toward the Sea People Village entrance as you continue deeper.

Helpful tips

  • A level 2 or higher diving suit is recommended for exploring comfortably.
  • Watch for aggressive fish like the Atlantic Anglerfish in the deeper zone.
  • If you are trying to clear the area efficiently, plan your oxygen route before committing to a long descent.

Quick note

If you meant a specific quest step or map entrance that is blocking you, the exact point is usually a story gate rather than a hidden shortcut. The most common answer is to keep advancing the chapter and then dive during the day until the deeper path opens.

TL;DR

Go deeper during a daytime dive, aim for around 130m+, and follow the main story path; the Blue Hole Depths open from the Medium Depth area and are not accessible at night.
