  Gubser flow provides an analytic model for describing the spacetime dynamics
of the quark-gluon plasma produced in heavy-ion collisions. Along with boost
and rotation invariance along the beam axis, the model assumes invariance under
a combination of translations and special conformal transformations in the
transverse plane, leading to a flow profile which evolves not just along the
beam axis, but also radially. We argue that Gubser flow and its associated
symmetry assumptions arise naturally as a consequence of Carrollian symmetries
for a conformal Carroll fluid, thereby providing a dual geometric picture for
the flow. Given the inherent ultrarelativistic nature of the flow, this duality
with Carroll hydrodynamics - which arises in the $c \to 0$ limit of
relativistic hydrodynamics, is natural. We provide a precise map between Gubser
flow and the conformal Carroll fluid, appropriate to capture the duality
between the two not just at the ideal level, but also with the inclusion of
hydrodynamic derivative corrections.
