You can camp on the beach in Seward, the spit in Homer and the Park on the Russian River. All great stops. Seward has great glacier trips on the boat where you will see seals, otters, whales, eagles and great scenery. Homer has great halibut fishing trips. No where in North America will you travel through mountain scenery as the highway will show you Dall Sheep and maybe Mountain Goats. Be careful of the moose on the roads especially at night. This is the trip of a lifetime.
