Level 5 - Opening gates problem [solved]

[Stashkin]

Hi there,
here's the deal: I don't want spoilers, just putting me into the right direction. Here's a pic of the gates I don't know how to open:

It's a place you access from falling down from lv4.
I can't find any switch, nor the hole I can possibly fall down to get to the area behind the gates.

Any hints please?

Hint:

Be patient and keep going down.

I shouldn't bother about it yet, 'cause I'll get there from the further levels - correct?

Correct. As a hint:

You get there from a secret further on
