Yellowstone has a web site that includes a page about pets visiting the park. I would include a link but HTML and links are prohibited in answers. They suggest leaving your dog at home because there are a lot of restrictions on what you can do with and where you can take your dog. These include limited travel, never leaving your dog unattended outside, and not being allowed in any hotels within Yellowstone. Oh, and pets are not allowed on boardwalks, trails or in the backcountry.

God knows...…..

Easy on your own. Sounds like you will have time where you could spend a day in each major location. Base your visits on weather. If it is cold and rainy, you may not want to be playing in Lake Yellowstone Depending where you are coming from, you can always head to the farthest location first and make your way back “home” for the night. Places to hit very early or early evening is grand prismatic. The place will be very busy other times. Norris is popular due to steamboat geyser. People have spent hours waiting to be lucky enough to see it go off. The area can get crowded but worth walking around the boardwalks to see things. Old faithful area is busy nearly all the time, especially around the predicted eruptions. Plan to spend time there just to walk and see other geysers. The old lodge will have a board with estimate times the next eruption of some geysers go off Lamar Valley. Dusk time. Lots of wildlife. Places to avoid: drive north from Norris to Manmoth. If it’s not convienent, just give extra time for anything at either location as there is construction that route (June 2018). The NPS website can provide more info There are lots of small hikes in areas. It depends on how strenuous you want to do. Each has its own treasures (views, wildlife, etc)

Hi Kearneytown - You will love Yellowstone. I assume you are talking about the Upper Falls and the Lower Falls. There are a ton of waterfalls in Yellowstone, but these two are the best. Ironically, you hike down to the top of the falls. They are super popular and it is very easy to find the parking lots for each of them. Sometimes the parking lots can be crowded, but in October you should be fine. Both falls are located in Canyon Village, which is kind of in the middle of Yellowstone, but maybe a little North and East of the exact middle. The parking lot for Upper Falls is just south of the main road intersection. You drive east just a bit off the main road to the parking lot. The hike is very short - maybe 1/8 mile each way and not too steep. There is a landing and with a rail that lets you look over the edge to see the falls. To get to Lower Falls, you have to get back in your car and drive north to the next parking area. I think it is called North Rim or maybe Lower Falls. Easy to find. There is a trail to hike between the two, but it is closed halfway up the trail and you would have to turn around. This is a bigger parking lot and has several different areas to park. The first parking area is the closest one to Lower Falls. There are signs to the overlook, but this trail is longer and steeper - I think it said 3/8 mile. Going down is not too bad, but coming back you will definitely be breathing hard - especially if you are not used to the altitute. But don't let that disuade you. It is the best view in the whole park. Standing at the edge of all that water is awesome. Another view that is also good is called Artist Point. It is on the South Rim so you would drive south of both of the parking lots and turn left by the bridge. You cross the river before the water goes over both falls and drive about 1/4 mile to the parking lot. This gives you a beautiful scene of the Lower Falls looking up the canyon and it is also spectacular. I hope this helped. Have a great trip!
