Display an object in Vue template

I have an object like:

Obj = {
  'min_mix': 1, 
  'max_mix': 2,
  'climbing': {
    'easy':[
      {
        'hour': 1.0, 
        'id':0,
      }
    ],
    'height': [
      {
        'hour': 1.0, 
        'price': 100
      }
    ]
  }
} 

I have to display this in my HTML:

min_mix : 1
max_mix : 2

climbing:

easy: 
hour : 1.0
id : 0

height:
hour: 1.0
price: 100

For now I use some v-for, but I don't have a good result, I don't understand how display correctly the array in easy and height?
