spelunked
Went underground exploring
Spelunked is the past tense of spelunk, meaning to explore caves as a hobby or sport.
The word comes from the Latin for cave and carries a slightly playful tone compared to the more technical "caving": We spelunked through the limestone caverns all afternoon.
Someone who spelunks is a spelunker.
