I have done two defined hiking trails, Hut Point Ridge Trail and Observatory Hill (Ob Hill) trail.
Hut Point Ridge was about 3 miles. This is where I first was able to Mt. Erebus the volcano.
Ob Hill hike was not very long but it was straight up and gave great views all around. There was a lady who was running it up and down 5 times. I ran for about 100 yards and my legs felt like cement.
Picture of town from Ob Hill.
A lot of parts of town look like a junk yard. There is stuff just stacked all over. If it does not have to stay warm and can freeze they store it outside.
