When visiting Amersham as tourists you may be little unexpected as the town does not seem to have much to see or do in it at first glance. However there are some great parks, such as Hervines Park round the back of the Dr Challoners Grammar School which has a wood and also there is a park behind the gym/swimming pool building.
Old Amersham is home to some a fantastic church and traditional clothes stores as well as old-fashioned streets. It is also home to the great Amersham Museum, a must-see for visiters to the area.
For the best weather come in March, May or June or perhaps Autumn due to commonly bad weather in August, being too hot in July and the increasing chance of disruption due to snowfall in winter months.
