  • Free event (admission applies)

This is a free drop in event. Open 11am until 3pm. Come and learn about how hydro power has been used at Castle Drogo from 1929 to the present day. Guides will be opening the Hydro for visitors to come and look inside. Please Note: The Hydro Turbine relies on the river level to be consistently high to operate so we are unable to guarantee it will be on during your visit. To get to the Hydro from the Castle Drogo car park please follow the Hunters path down to the Iron Bridge, cross over onto the Foresters track and follow the path towards Fingle Bridge. Alternatively you can access the Hydro from Fingle Bridge by following the Foresters track for around 40 minutes.
