We perform a calculation for the total and differential cross section of the $\\gamma p \\to K^+ \\eta \\Lambda$ reaction by including the contributions from the $\\Lambda(1670)$ intermediate state decaying into $\\eta \\Lambda$ dominated by $K^-$ and $K^{*-}$ mesons exchanges, the nucleon pole and $N^*(1535)$ resonance decaying into $K^+ \\Lambda$ dominated by exchanges of $\\omega$ and $K^-$ mesons.
