Catcott Lows NNR (Click for Map
Managed by Somerset Wildlife Trust 
You can see the unexpected at any time of year on this reserve but I don't think anybody will disagree when I say that the best times are definately during winter through to April/May. 
Large numbers of wildfowl are present over the winter period when the reserve is flooded, and later into spring when waders and other migrating birds make an appearance, when the water levels drop a bit, there can be some quite unexpected visitors. 
Also with a little patience, due to the large open area, good views of birds such as Marsh Harrier, Hobby, and migrating Hirundines can be expected. 
Page Index:- 
1 - Car Park and Hide 
Follow the track after turning left on lane from Burtle, or second right (straight-on) from Catcott village (instead of 90° left). 
The hide is called 'Janes Drove Hide'. 
2 - View from Hide 
View from inside the Hide, looking out at the Reserve area.

Second Hide 
Those of you feeling energetic can take a stroll across to the other hide (Drove Hide). It is to the right of the reserve (just make it out on the "view" picture).  
If you walk back to the track entrance and turn left, walk down the track and turn left again then follow this track, you'll eventually find the other Hide in front of you. This hide gives an alternative view of the reserve. 
If you're feeling even more energetic, walk back from the second hide until you meet the main track, then turn left. 
The track eventually leads you to some woodland on your right. 
Keep walking straight-on on the main track and you come to some open country, overlooking the back-end (most westerly point) of the Shapwick Heath Reserve.
