Field Trips

Come along and join us for an enjoyable trip. You do not have to be an expert as everyone has varying degrees of knowledge and interests. Bring along a packed lunch if you plan to stay for the day, a drink, suitable clothing and footwear (check with the leader to find out if wellies will be needed).

Coach Trips

Unless stated otherwise you do not need to book for most field trips and there is no charge. One exception is the coach trip. For coach trips please email Pascale Genevois to book a seat.

Indoor Meetings (Sep-April)

Our talks are free to members and non members alike, but donations are accepted for refreshments. Unless otherwise stated all indoor meetings are held at the Cardinal Bourne Hall in Priory Street, Colchester [see map] and usually start at 8.00pm. The Hall is situated at the East Hill end of Priory Street with car parking almost opposite by the Roman Wall at the cost of £2.


Please remember there are special events such as the Christmas Social in December & AGM in January each year which start earlier. Don’t get caught out!

  • CNHS Committee Meeting
    Wed, 23 Sep
    CNHS Committee ZOOM meeting
    A closed Zoom Meeting for our Committee Members

Your health and safety

As part of our insurance requirements we do occasionally have to review our procedures at events to ensure that we not only look after our members, but ensure that the committee and walk leaders are not left open to malicious prosecution for accidents that can occasionally occur. The committee is now required to provide Risk Assessments as part of that insurance. This should not affect anyone coming out with us or attending an event, but you may be asked to listen to a short safety talk before setting off. A common sense approach to safety is encouraged to avoid the need for more prescriptive health and safety regulations that could affect our ability to do the activities we have enjoyed since the Society was formed in 1953.


First aiders

Some of us are already trained as first aiders by the organisations for which we work, however it is not a requirement for CNHS to provide a qualified first aider for walks. Despite this, the committee feels it would be sensible to provide a portable first aid kit so all walk leaders will carry  one with them.  Members are still advised to take sensible precautions to ensure their own safety when attending organised events.
