There are 65 sites available for you and your doggo, as well as a few indoor cabins and lodges that you can choose to stay in. You and your pup are totally welcome to enjoy the RV spots, but you're doggo isn't allowed to hang out in the lodge.
You'll have access to cell coverage, showers, laundry, wifi, TV, sewer systems, and flushing toilets! There are also outdoor grills and picnic tables. If your dog is well behaved, they're welcome to hang out in the RV park, but you'll have to keep your pup leashed. The good news? There's no additional fee to have your pup join you! The bad news, your doggo is not welcome to join you if you plan to stay in the lodge or cabin areas, so be prepared to kennel your pup if you insist on staying in a cabin.
You are also required to clean up after your dog at all times! There are lots to do in this part of Alaska, including things like fishing from the beach, hiking, enjoying the Cook inlet, and even viewing the volcanoes Mt. Redoubt and Mt. Iliamna.
One thing you need to keep in mind is that you and your doggo, no matter how plush the facilities, will be enjoying Alaska in the summer, so there will certainly be a chance that bears will be in the area. Ensure that you and your dog are bear-aware, are taking the proper camping precautions, and are always staying observant of your surroundings.
