It is hard to find parking in loya.

It's a neighborhood perched on a cliff in northern San Diego.

A long staircase that leads underground through the cliff and spits you out inside a secret cave.

This passageway is the only way to get there from land.

Every few minutes, the people waiting to enter the tunnel get to watch someone emerge

from it.

The small groups spill onto the sidewalk, out of breath, maybe a little sweaty.

I didn't think it would be that steep.

There's so many stairs in a room.
