Don't go if you have heart problems!
This is a great hike and worth it when you get to the top, but be warned! If you have heart problems or are a smoker...pace yourself! Once you are almost at the top, they hit you with this crazy staircase...just looking at it makes you want to turn back around!
But, at the top, it's beautiful and worth it. You can even buy a little certificate for yourself saying you climbed to the top.
DON'T GO WITH A TOUR!! Just drive there! It's only $5 for parking, $1 for a bottle of water. If you walk in, it's $1 per person, so if you have 5 people, just drive in and park.
