We report on the intershell electron transport in multiwalled carbonnanotubes (MWNT). To do this, local and nonlocal four-point measurements areused to study the current path through the different shells of a MWNT. Forshort electrode separations $\lesssim$ 1 $\mu$m the current mainly flowsthrough the two outer shells, described by a resistive transmission line withan intershell conductance per length of ~(10 k\Omega)^{-1}/$\mu$m. Theintershell transport is tunnel-type and the transmission is consistent with theestimate based on the overlap between $\pi$-orbitals of neighboring shells.
