Public Transport: From the Frankfurt Central Station take Regionalbahn RB22 direction Limburg. Get off at Idstein Bf. Take bus 228 direction Idstein-Lenzhahn and get off at Idstein-Lenzhahn Ortsstraße. From there you have to walk 450 m.
Car: I have no idea where you all live so use the navi…..would you even trust me if I sent directions here? One day I’ll try and give the wrong directions and see if anyone is reading this emails…
