Early June may be a little too early in the season for this park. My girlfriend and I definitely got snowed on multiple times, though none of it stuck. On the plus side, it was true mountain weather; if you don't like it, wait 15 minutes.
The active weather was actually a plus for photography as well, since there were almost always dramatic clouds in the sky. The clouds would build up behind the mountains, then gradually roll down and dump on us for a while, then clear up again. I mean, just check out this cloud drama:
The other plus of early June was that the park was not very crowded, which meant we had no trouble parking our car (rental Buick LaCrosse) or getting a campsite.
We also encountered plenty of elk, chipmunks, and Wyoming ground squirrels, but only a couple marmots. The ground squirrels liked to hang around our campsite, but were never a nuisance. We were pretty diligent about keeping our food put away though.
Sunrise was at about 5:30am. I was able to pop out of the tent in Moraine Park campground at 5:15 and make it to the spot to take this photo at 5:30 without too much of a rush.
Also, we found the Rocky Mountain National Park Dayhiker's Guide particularly useful. It's also got some good photos to give you an idea of where to go for what. The only error we spotted was that Bierstadt is actually 2.0 miles from Bear Lake, not 1.6.Ok, here's one last shot near Deer Mountain.
