Lappa Valley Steam Railway nr Newlyn East in Cornwall. here
Took my train mad 2yr old and 5month old DT's. Had a brilliant time. Three different train rides, things to climb on and jump on. The nature walk was just right for the 2yr old whilst Grandma stayed with Dt's.
Staff friendly and helpfull although the changing facilities could do with a rethink as not very welcoming but at least they were clean.
All in all a lovely afternoon.
