Spelunking requires careful planning, sturdy gear, and respect for fragile cave formations.

We spent the weekend spelunking in the newly discovered cave system despite the rain.

Her weekends were filled with spelunkings that took her to remote, silent caverns.

The spelunkers navigated the narrow, dripping passages by headlamp, awed by the cave's ancient formations.

We sheltered in the spelunk until the storm passed, marvelling at the ancient markings on its walls.

We plan to spelunk the newly discovered cave this weekend.

The experienced spelunker carefully mapped the narrow passages before leading the group deeper into the cave.

My friend spelunks the hidden caves along the coastal cliffs every weekend.

Yesterday, we spelunked deep into the limestone caverns until the passages opened into an underground lake.
