Involves a great excursion. We do not want to say more, because it could spoil the fun of the hunt! Great cache hide!

All's well that ends well...

Beyond Ultraviolet

bigFOOT

Blood & Guts in Virginia is an excellent adventure cache, combining some challenging locations with some mind-bending riddles and puzzles. Many take over a year to complete this cache, and many who start it never complete it.

Blood & Guts in Virginia (aka Iron & Stone)

Blowing Cave Bonus Cache

Tennessee cache with some great and nasty climbing!

Byrd Surface Camp

Chomolangma

A classic extreme cache in Maryland which involves an excursion into the dark. We do not want to say more, else we give away too much! An excellent cache!

Dark

A really sick 5/5 highway bridge cache in Sweden! Major drama!  Most bizarre, however, is the fact that many seekers tackle it without climbing gear. Some of the pictures uploaded to the site by finders are truly horrific! The best pic/story is the log by the couple who decided not to go after it due to safety concerns, but "asked" their 4-year old son to go fetch the catch. The picture of him looking at the bridge is priceless!

Deathwish?

A classic extreme hide in North Dakota which involves a vertical or near-vertical climb.

Deep Freeze

An excellent 5/5 multi in northern NJ that ends with a really fun and extreme hide. You will likely need gear -- we did!

Devil's Den

Down and Dirty

Drop in at Shanty

Edisons Dark Rock Cache

A great 5/5 multi-stage extreme cache in Germany.
