On Friday, Lisa and I went to RSPB Otmoor, in Oxfordshire. Our main goal was to see Brown Hares, and we didn't, but we still had a lovely time at this gorgeous grassland-and-wetland reserve. The weather was stunning - hot sunshine and hardly any breeze - probably not the sort of day for hares to be gallivanting about, in fact. Anyone thinking of going to Otmoor should point their satnav at Otmoor Lane (the entrance is at the end of it), and not be perturbed by the total lack of signage on the way!
Before you hit the reserve proper, there's an area of incredibly lovely meadowland, with trails, which is open in spring/summer only. Lots and lots of insects.
