Google search , followed by phone call. Great first call , felt I was talking to an independent and knowledgable travel company . Loved the flexibility it gave us ; the ability to feel that we were not being herded on a tourist track , that we were achieving something , yet we still didn't have to navigate and had the security of knowing that their was a team behind it all. Yes - great . We were unsure prior to going whether it would rally suit our 3 boys aged11,10 and7 and hence whether we'd make the most of it . In fact it turned out really well - with an added bonus of us all getting to meet new people and the kids making new friends slightly older than you might expect!! But really your staff are the prize - confident, well rounded but not over bearing; interesting and interested . Not an everyday find . A special mention to kat and Sam who are welcome to pop round for a cup of tea whenever they want - although no mountains in east finchley I'm afraid ! We can do the tube though if that helps .
