Langport is on the River Parrett which was used for bringing trade into the town where it had its own Customs House. There are many historic features in the town such as the hanging chapel and the portcullis with access to the Somerset Levels countryside.
Just on the edge of the town on Bow Bridge, is the Langport Visitor Centre. The Centre holds an interesting array of displays, exhibitions, including the hands-on "Discovery Room", and useful information about the local area, market towns, events and the River Parrett Trail.
Particularly useful information is on walks around the area and a bit about the history of the market towns of the Somerset Levels and Moors. You can also buy your River Parrett Guide from here that contains maps and information on attractions to visit along the River Parrett Trail.
Cycle hire is also available in the Visitor Centre for adults and children, and The Parrett Cycleway branches out from the centre following the line of a disused old railway line for one and a half miles to Muchelney. From here you can explore the countryside on quiet country roads.
The River Parrett Trail is a 50 mile, long distance hiking trail that extends from near Crewkerne to Combwich near Steart, just south of Burnham-on-Sea. You can complete the whole trail over 3 or 4 days or break it up as a series of shorter walks during your holiday in Somerset.
The trail follows the River Parrett from the Dorset Hills where it starts through the Somerset Levels countryside and characteristic Somerset market towns, ending at its mouth at Bridgwater Bay. The going is relatively easy as most of the walk is on flat ground. If you want more of a challenge along the way you can have a go at canoeing on the Bridgwater and Taunton Canal or hire a bike from the Langport Visitor Centre and explore further afield.
