I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Totternhoe Knolls is part of the Chiltern Hills, an Area of Outstanding Natural Beauty (AONB). The chalky soil of this forty acre nature reserve and picnic site supports a wide variety of characteristic and unusual chalk downland plants and wildlife. In addition, Totternhoe Knolls has a fascinating historical legacy and offers superb views towards Dunstable Downs and Ivinghoe Beacon in Buckinghamshire, also part of the same Chiltern Hills chalk formation.
Totternhoe Knolls is owned by Bedfordshire County Council and can be visited at any time of the year. It is an ideal place to combine a picnic with a short or longer stroll in the countryside.
