I think the cost is $20 per vehicle

Check out their website. They would not allow me to post the website here, but they do have one.

Yes, there is an entrance fee. I don’t remember how much, but it wasn’t much.

Two hours is plenty, if you want to walk more you can extend your time

We did the island trail in about an hour. We took our time and stoped to read the whole way. We spent another hour in the visitor center, watching the movie, checking things out and taking in the amazing view.

Yes, you can see the remains of some dwellings from the Island Trail. Bring water if your going to walk the trail. The descent to the trail is not to bad but coming out is all up hill!

The main trail down starting with the railed stairs leads to the island Trail. It is your only choice to get to the dwellings. The first dwelling you can reach doesn't require that you go too long on the paved trail. I didn't like going past this point too far because it had just rained heavily the day before and the rubble made it too easy to slip. There is no guard rail at this point so once I got to the first dwelling I decided to head back. Also stay hydrated. The combination of elevation above sea-level and dehydration ( happens fast if you forget to hydrate) made it a little scary for me.

Hi, I am not sure if it open during the shutdown but I believe it is on reservation land which is not tied to the government shutdown.

No I don't think so. The sentries are paved and there are many steps, so I think that the park authority doesn't allow dogs.

Yes
