We consider a class of second order Hamiltonian systems $\ddot q=q-V'(t,q)$ where $V(t,q)$ is asymptotic at infinity to a time periodic and superquadratic function $V_+(t,q)$. We prove the existence of a class of multibump solutions whose $\omega$-limit is a suitable homoclinic orbit of the system at infinity $\ddot q=q-V'_+(t,q)$
