The earth is amazing and deadly. The crater hike is a must and would rate a moderate hike in proper gear. If you've done your research, go counter COUNTER CLOCKWISE on the hike as to cross the lava tubes at the end and crossing the highest part of the volcano will be easier as well. So if you see the tube early on your trek, I highly recommend to go back the 15 minutes. Parking is very limited for the hike, so come early like before 9am and you'll have no problem if it. Bring lots of water as there are no shade when your are on the crater part of the hike. We took about 3 hours to complete as we stopped and double backed on some parts of the trail. Once on the crater, follow the rock piles that creates a path across. Do drive to the visitor center as there are toilet facilities, park rangers that does a great overview of the park, and gift shop to commemorate your visit. If you have the time, there is a drive all the way to the Crater Rim Road all the way to the most southern tip. Leave at least 2 hours to do this.
