The hike was medium to low level difficulty, but the altitude made us very short of breath. Incredible views and landscapes.out of our group of 7, three paid for the horses (about $80), and the 4 of us walked. Bring layers - we took the morning hike and it started off chilly, got very warm, then windy at the top. Marshmallow roasting was fun, our group opted to get the pizza from the guy who cooks it over the steam vent. It’s expensive ($50) but was delicious, our group split a large and it fed 8 people. Really unique experience. The horses follow you most of the way up in case you can’t do the hike. Rent the walking stick from the kids in the parking lot, near the top the lava gravel gets slippery.
