I counted eighteen on one tree trunk. On this visit I also saw several Hornets flying lazily around in the afternoon sun. Owned by Milton Keynes Borough Council, open daily. Cars may be taken in for a small charge. Alternatively, you can park in the lay-by on the Emberton to Olney road and walk in.
Public footpaths run through the park.
Emberton Park is a large country park of about 170 acres. Much of the area is taken up by several large lakes which are used for boating and fishing. The North and West edges of the park are bounded by the River Ouse. This is an excellent site for dragonflies throughout the season. Most of the 17 Milton Keynes breeding species have been recorded from here.
