Being local I have for a long time been aware of the country park around Blythe Valley Park and this great weather (as well as having more time to enjoy our environment) has taken me and Millie to Blythe Valley Park regularly. It is though no coincidence that the re-opening of the truly excellent Java Coffee Lounge has helped motivate me.
I have posted a few photographs I took today, this also includes one of a map on the route.

For short term I park on the free two year spaces at Java Lounge but please use their services and support them. The service is great and it is an independent business. For longer stays stop off at the security building (on the left just after entering to get a permit).

Hello. Have you ever parked at Notcutts and walked over to this reserve? Is that possible? Three people in three cars it would be easier to park at the garden centre than explain the way in to the business park. Thanks.
Certainly, do it regularly. Remember though you can only park for three hours on the car park, which is owned by Tesco.
