There are many more opportunities to explore in the vicinity of Leiden.
Think about Wassenaaar, The Hague, the royal and government residence, and the neighborhood fishing village of Scheveningen, or the city of Delft of Rotterdam, Amsterdam.
In Amsterdam I can guide only small groups of 4 persons.
I would also be happy to guide you on a tour through these cities. Every place has its own charms and can be best explored either on foot, in a boat, on a bicycle, or in the comfort of a bus.
Contact me to advise and help you with the arrangements of a unique tour or day-trip.
