Sulphur Banks(Hawaiʻi Volcanoes National Park)
This will report the image to moderators for review. Are you sure this image is offensive?
Walk through an area concentrated with stream vents. The vents are piles of rocks and out of them pumps a constant flow steam and sulphur dioxide. You can get up right next to them. The gas coming out of them is warm to hot and suffocating. The rocks are covered in a coating of crystalline sulphur.
Start at the Visitors Center.
Which maps cover the area?
Follow the walkway through the sulphur banks. The trail crosses the road. To the right are more steam vents with less sulphur coming from cracks in the ground. The trail goes along the Kīlauea caldera, with good views down into it and of the Halemaʻumaʻu crater where the big stream column comes from and where the magma lives. To the left the trail goes through forest back to the Visitors Center.
Do you need any permits? What's the cost?
How can I find more info? Any guide books?
