  Spacetime in the vicinity of an event horizon can be probed using
observations which explore the dynamics of the accretion disc. Many high energy
theories of gravity lead to modifications of the near horizon regime,
potentially providing a testing ground for these theories. In this paper, we
explore the impact of braneworld gravity on this region by formulating a method
of deriving the general behaviour of the as yet unknown braneworld black hole
solution. We use simple bounds to constrain the solution close to the horizon.
