You'll pass through the lovely Lopwell Dam Nature Reserve with habitats including mudflats, freshwater marsh, wildflower meadow, scrub-grassland, saltmarsh and semi-natural woodland.
The route then continues north towards Calstock joining the River Tamar for a splendid waterside stretch through Gunnislake and Luckett.
You then leave the river heading through Milton Abbot before crossing the river again at Dunterton and proceeding to the finish at Launceston.

In Calstock you could head to the Tamar Inn for refreshments on the walk. The historic 17th century free house sits on the banks of the River Tamar. It was allegedly once a meeting place for smugglers and highwaymen. Built on a split level, it sits close by the waterfront in the village centre at a postcode of PL18 9QA.
Near Gunnislake there's the excellent Rising Sun Inn. The charming, oak beamed country pub dates back to the 17th century. They have some lovely terraced gardens where you can enjoy a meal with a view over the Valley. You can find them at postcode PL18 9BX for your sat navs. The inn is dog friendly if you have your canine friend with you.

Further Information and Other Local Ideas

The route is coincident with the Tamara Coast To Coast Way an 89 mile route running from south to north Cornwall. The trail starts at Cremyll and runs all the way to the coast at Morwenstow.
In Calstock consider taking a small detour from the route to visit the National Trust's Cotehele House. It's located just to the west of the quay and includes a fine Tudor House, formally planted terraces, the Valley Garden with medieval stewpond and dovecote, the Upper Garden and two orchards.
The Tamar Valley Line is a great way of seeing the area from a different perspective. The scenic railway takes you through rolling green, sleepy villages and beautiful river crossings. The highlight of the journey is when the train slowly creeps down over the impressive Calstock viaduct and you are 120 feet high looking down on the river below.

Lopwell Dam - - 84226

Lopwell Dam. The purpose of this dam is less to hold a great deal of water behind it and more to stop salty tidal water coming up stream. This makes the river water available to be extracted for the public water supply.

The Viaduct, Calstock - - 531588

The Viaduct, Calstock. Taken from a river launch as we approached the dramatic railway viaduct over the Tamar at Calstock. Dusk was falling so the colours are somewhat muted. This is a remarkably attractive structure considering it is made out of concrete blocks! The blocks are huge, typically 5ft x 3ft x 2ft, but varying to allow for the tapered columns. According to (not necessarily terribly reliable) research on the internet, it is 108ft to the underside top of the arches from ground level. There are 12 arches in total, each one spanning 60ft. Of these 12, four arches actually span the river (not 6 as you will find reported elsewhere). The engineers were R. Church & William Robert Galbraith and the bridge was constructed between 1904 and 1908.

New Bridge, Gunnislake - - 1211279
