A team of OUCC cavers visited one of the islands off the coast of Chilean Patagonia in 2008, at the same time as other parts were being explored by French and Chilean cavers. See: https://www.earth.ox.ac.uk/~chrisd/mdds08/files/Prospectus.pdf

For an overall and almost up-to-date account, the following was presented at the UIS congress in France two years ago! https://www.researchgate.net/public..._Chile_a_masterpiece_of_the_world_geoheritage

So the answer is yes, there are plenty of caves in Patagonia, but they're best accessed by the sea.
