Dragons live deep underground in caverns, usually with many passages and inner caves where the treasure is kept.
Some areas, like Wales or the Catalan region around Barcelona, have strong fire-dragon traditions.
Visit places with dragon or drake names such as Dragon Hill near Uffingham on the Berkshire/Oxfordshire borders, close to the huge chalk horse symbol of the Celtic horse goddess Epona.
Go also to those spots where there are dragons legends, such as Krakow in Poland where the dragon lived in a cave beneath Wawel Hill under the castle. You can be sure people in times past experienced dragon energies there and so wove the legends. Enter ‘dragon’ in the regional website of the place you intend to visit.
Explore dry, rocky, sandy regions, like Almeria in the south east of Spain. Visit also the bush lands of Australia and the Midwest of America and New Mexico, where European and Scandinavian settlers from the Old World carried the dragon mythology and the absorbed energies to join with the indigenous myths.
Explore the sacred sites of the creatrix rainbow serpent in Australia. In American, Serpent Mound in Ohio, just east of Cincinnati, which was used for worship by the Adena Indians, somewhere between 800 BCE and CE 100, is another perfect dragon location.
Most deep forests also have their share of dragon legends, especially in Germany. Visit different cavernous or rocky areas and feel for your dragon.
You may even find friendly fire-dragon energies near seaside caves in sandy coves (watch for tides). Western dragons traditionally live alone except for mating.
Collect the legends and your own impressions in your Book of Shadows.
