while not a feat, you might want to buy this if you got a large enough burrowing creature to ride.
it not only allow to train creatures that normally you can't train (that have less then 3 int and are "friendly or helpless"), but also allow you to burrow with them when riding them.
that include training burrowing vermin and insects etc.

Some source of tremorsense or similar would be useful for navigation. A quick search on d20pfsrd finds that beside's Paizo's dwarf-only feat for this (stone sense) and a stone giant only one (stone awareness) someone's made such a feat for cats, whisker sense.
Spring attack and related feats could be unreasonably useful for a burrower.
