There is nothing wrong with camping near the trailhead and doing day hikes. It's too bad you are so far north. There is generally more snow up there than there down here. (I live in Pueblo. Oh, it's snowing now. :)) Most of my day hiking is in the Wet Mountains or in the Sangre de Cristos.

There is no sense in planning too far ahead, as nobody knows what the weather will be like then. I would check the roads. Many of them washed out in the flooding this year.
