Know Before You Go
To reach the flames, you'll need to climb stone stairs. There are no arrows pointing where you should go, but it's easy to find because there is no other way. The climbing takes 15 to 20 minutes, at the end of it you'll get very tired and probably sweaty, but it's worth it.
It's better to go there at night to see the flames. It will be dark when you climb but you can use a flashlight (your phone's light is fine). At night the flames look better. You can bring marshmallows or sausage to cook there. And a little wine to make it perfect. The most important thing is to bring water with you, as you'll get thirsty. Wear sneakers or other shoes suitable for hiking. Bear in mind that the park closes after 8 p.m.
