Yellowstone National Park, WY, May 2026
Park Information
The campgrounds vary for opening and closing. Mammoth Campground is open year round, depending on weather. The longest campground season is May to mid-October. The shortest campground season is mid- to late June to mid- to late September. Fishing Bridge RV Park, the important campground for us, is mid-May to mid-October. Water is available during the camping season at each campground. Mammoth Campground has water turned off for the extended winter, but vault toilets are available. The park website is here.

- There probably is poison ivy, but it was not prevalent, when we were there.
- There is short term RV parking at Fishing Bridge RV Park check-in. Not all campgrounds have RV spots, so not all will have space at check-in.
- A vehicle pass is $35 for a 7 day pass to enter the park. Once in the park, you are not charged. For longer stays, visiting the Grand Tetons, or grocery runs, consider an $80 annual America the Beautiful pass.
- Roads and bridges can be on the narrow side, and tourists blocking the road make it worse.
- Roads and bridges should be adequate for normal cars and RVs, but they are not rated for oversized loads or weights.
- Most roads are adequate, but there are some gravel side roads and heavy traffic roads with bad wear. Frost heaves are a problem too. They are natural speed bumps.

- Kayaking and canoeing are allowed on some lakes, but not on rivers.
- Swimming is highly discouraged, and the few places are often closed due to wildlife or unsafe water.
- Road biking is on all park roads, but it might not be that safe with the bears and reckless tourists.
- Biking is not typically allowed on trails, but they are allowed on the dirt roads.
- Technically, Lake Village has an employee disc golf course, but it is not officially maintained or for public use. Some goals are buckets.
Park Overview
- Read a Yellowstone National Park tour guide to determine when the things you want to see are visible in the park.
- Visit from mid-May to mid-June and September to mid-October. The families and mosquitos ruin the experience from mid-June to September.
- You can book in two week intervals, buy you have to talk to a person to get them linked to prevent moving in the middle of the stay.
- The park is enormous. You should plan for at least a week to get a reasonable experience.
- If you are staying in hotels or cabins, consider relocating halfway through.
- If you are staying in a small campground, consider relocating twice.
- If you are in a large RV, expect some long days to see the other side of the park.
- Fishing Bridge RV Park Loop E is modernized, but expect your site to suck. There is no real maintenance of the grass and weeds, by design. Expect to have your chairs on the concrete.
- Most other campgrounds have narrower roads and smaller sites. These are cheaper, but they require smaller campers or tents to safely fit. They are also no full hookups.
- Carry bear spray everywhere, except, maybe, at visitor centers. Expect people to beg you to spray them with your bug spray. It will be hard, but resist the urge to squirt them with bear spray.
- Watch the road; animal jams can appear anywhere at any time during the day. They are uncommon at night, but then you have to be careful of hitting an animal.
- Elk and Bison are common, but they still result in animal jams, especially mid-June to August.
- Bear jams can be bad, and people are rude about blocking the road.
- There are vault toilets spread around the park.
- There are gas stations in the park.
- The main restaurants are the park managed grills, which are expensive and mediocre. If you can wait two weeks between visits, the food tastes better.
- Expect some snow in May

- Loop A-D are gravel sites. Loop E are concrete sites.
- Packed a bit thick and tight in the RV Park, but you should spend most time out and about.
- Did not see much poison ivy
- Wild animals, including bears, are sometimes seen near Fishing Bridge. Driving to bath house or carrying bear spray is safest

Driving Directions
On the way in from the North, we stopped in Gardiner. The RV park options were not great. It is a bit of a long day, but it was better to do it in a single day with a stop in Gardiner and Mammoth to catch your breathe. Next time, we will likely come in from the east.
