First Backpacking Trip

We went on our first family backpacking trip last weekend.  We hiked up a steep trail to Annette Lake.  It was about 8 miles roundtrip to our campsite.  One trail map said 1,500 ft elevation gain and another said 1,900 - either way it was steep!  There was a modicum of whining on the way up but it was worth it at the top - glacier lake, swimming, campfire.  Everyone wants to do it again.
