Bowling Green Marsh nature reserve is close to the village of Topsham. It features a viewing platform, which looks over the Clyst (a tributary of the River Exe) and a hide which overlooks the marshes used by birds at high tide. In winter flocks of wigeons, teals, black-tailed godwits, brent geese and avocets feed at the site. In spring and summer it is quieter, but in the evenings swallows and sand martins feed over the water, migrant warblers sing from the hedgerows and as summer wears on wading birds turn up, some still in their magnificent breeding plumage - so it's always well worth a visit. Bowling Green Marsh is less than 10 minutes walk from Topsham's quayside and railway station. Exminster Marshes and Powderham Marshes nature reserves are on the west side of the estuary. Winter migrants also use this side of the river and in spring lapwings and redshanks breed here. Both reserves have public trails which are open all year round.
The area in which the hidden is wheelchair accessible but users would probably need help to reach the cache.
