  Neutrino oscillations have been probed during the last few decades using
multiple neutrino sources and experimental set-ups. In the recent years, very
large volume neutrino telescopes have started contributing to the field. First
ANTARES and then IceCube have relied on large and sparsely instrumented volumes
to observe atmospheric neutrinos for combinations of baselines and energies
inaccessible to other experiments. Using this advantage, the latest result from
IceCube starts approaching the precision of other established technologies, and
is paving the way for future detectors, such as ORCA and PINGU. These new
projects seek to provide better measurements of neutrino oscillation
parameters, and eventually determine the neutrino mass ordering. The results
from running experiments and the potential from proposed projects are discussed
in this review, emphasizing the experimental challenges involved in the
measurements.
