My partner and I visited Chugach National Forest a few times while we were staying in Girdwood for Labor Day weekend. Having been my first time in Alaska, I was surprised at how large this state park actually is.
The park is magnificent and majestic, that is without saying. Because it's so large, there are many places and trails and activities. There's a salmon viewing area on the drive to Whittier, which is actually a lot more interesting than it seems. We also went rafting at the Spencer Glacier, but that required a special train on the Alaska Railroad to get to. While we were on the train, I did see a National Park Service ranger leading a group on a hike – so that's another option I didn't even know about.
Overall, I think because the Chugach National Forest is so large, there isn't as much infrastructure or information available, but is still an amazing place with pristine mountains.
