We stayed at Iditarod, which we liked the best as it offered more expansive views since its around the corner. Plus, its much closer to town and Seward has great bars/restaurants and shops.

This campground has stunning views alongside the creek going into the start of Kenai Lake, which is an excellent place to kayak or standup waterboard. Great place to stay for a night on the way to Seward.

Great views, as long as you can find one of the flat spots, overlooking Gull Lake.

We stayed at the Fall Lake Campground en'route to a BWCA trip through Snowbank Lake. Was great for prep and come civilization before going deep in.

I'd recommend Gafvert if you want a deeper woods experience without many people. Accessible trails, good, flat sizeable spots.
