The mobile team currently worked on a nearby feature that has been
enabled on various wikis including Wikipedia:

Try it out here:

Currently and tragically it is disabled on Wikivoyage.
It opens the question of how should a nearby page work on Wikivoyage?
Should it surface nearby places of interest - e.g. Statue of Liberty,
Empire State Building or should it surface nearby places to visit -
e.g. Boston, Massachusetts, Philadelphia, Pennsylvania (I could see it
being useful as an addition to the "Go next" section of an article -
especially if with a tweak or two we allow users to input coordinates
other than the current location) or maybe it should do both?
Personally I'd prefer the emphasis on nearby places to visit but I was
interested in other's thoughts as I've heard arguments for places of
interest. This also raises the question of how close constitutes
nearby - is 100 miles / 160km a nearby place?
Whatever happens please let's get this enabled on Wikivoyage! This
feature was made for it :)
