Northampton to The Wash including the Grand Union Canal (Northampton Arm to Gayton Junction)

With support from the Inland Waterways Association, Friends of the River Nene and others, and drawing on his longstanding connection with the river, Roger Green has thoroughly revised and updated this popular guide. A new design includes thorough navigation notes alongside more detailed maps of the canal and river, showing the main features of the navigation. Helpful tables indicate mileages and likely timings between locks to help with passage planning and also provide further information on all the moorings, facilities and services, many of which have been much improved in recent years. Other features of interest such as canoe launch access and portage points are also shown. Details of facilities, walking and cycling routes and local history add useful information. Photographs help to highlight points of interest along the way and confirm this guide to be the essential companion for anyone planning to navigate the river, whether by boat, canoe, bicycle or on foot.
