Try reading books on the subject and trying it yourself; it is relatively easy. A great book to help is "Hillwalking and Scrambling" by Steve Ashton ( available on Amazon for much cheapness); lots of great hints and tips not only on map reading but reading terrain and weather, right clothing for conditions, etc. Now it is summery weather (mostly, touch wood) you can get out and about safely without getting too lost. Have fun and enjoy it.
