  We extend the recent proposal of hidden conformal symmetry to the
four-dimensional spacetimes with rotational parameter and NUT twist. We
consider the wave equation of a massless scalar field in background of
Kerr-Bolt spacetimes and show in the "near region", the wave equation can be
reproduced by the $SL(2,R)_L \times SL(2,R)_R$ Casimir quadratic operators.
Moreover, we compute the microscopic entropy of the dual CFT by Cardy formula
and find a perfect match to Bekenstein-Hawking entropy of Kerr-Bolt spacetimes.
The absorption cross section of a near region scalar field also matches to
microscopic absorption cross section of the dual CFT.
