Stackpole National Trust nature reserve:
This manmade reserve is great to visit at any time of year. In spring, the woods are carpeted in wild garlic, wood anemones and bluebells and in late May the three arms of the lake are covered in lilies. Mere Pool Valley, at the back of the stunning beach of Broad Haven South, is a delight, with several orchid species and over 22 different dragonflies recorded.
Autumn and winter are a great time to see migrating birds; bitterns make regular visits and the robins and blue tits will feed from your hand. The highlight though, is the chance to see otters in the wild, with two families living in the lakes.
