  Many practical applications of high T$_c$ superconductors involve layered
materials and magnetic fields applied on an arbitrary direction with respect to
the layers. When the anisotropy is very large, Cooper pair currents can
circulate either within or perpendicular to the layers. Thus, tilted magnetic
fields lead to intertwined lattices of Josephson and Abrikosov vortices, with
quantized circulation across and within layers, respectively. Transport in such
intertwined lattices has been studied in detail, but direct observation and
manipulation of vortices remains challenging. Here we present magnetic force
microscopy experiments in tilted magnetic fields in the extremely quasi-two
dimensional superconductor $Bi_{2}Sr_{2}CaCu_{2}O_{8}$. We trigger Abrikosov
vortex motion in between Josephson vortices, and find that Josephson vortices
in different layers can be brought on top of each other. Our measurements
suggest that intertwined lattices in tilted magnetic fields can be
intrinsically easy to manipulate thanks to the mutual interaction between
Abrikosov and Josephson vortices.
