1. IF you can, get reservations for the Old Faithful Inn. If you go after Labor Day, you might get reservations. If not, we prefer West Yellowstone. See the grizzly and wolf display there. Be careful==bears wander through town late at night!
2. WHATEVER time you get to the Inn, make dinner reservations! Reservations are a MUST! If you wait, you might be eating at 9:30 or 10 PM!
3. If you stay overnight at the Inn, Turn YOUR CAR ALARM OFF==the buffalo will scratch themselves on your car in the middle of the night.
4. After Labor Day, many things will be closed. However, the elk will be breeding and bugling. Geese will be migrating and bears will be trying to fatten up.
5. To see Old Faithful, go to the platform above the main entrance. Get a drink (there's a coffee kiosk and small bar just inside the door) and sit back.
6. Dress warm. Week after Labor Day we got snowed in.
7. Take fly tackle! Try the Madison near the West Entrance. Licenses are available in the Park.
8. Best place to see wolves is Lamar Valley at dawn.
9. Hayden Valley is a great place to see wildlife. Last trip, we say a grizzly hunting elk there and watched him for about 1/2 hour. He/she never found the calf he was looking for. Up by Sylvan Pass is a good place to see grizzlies. Dropping down to Cody and along the North side of the Lake are good areas to look for moose.
10. When you leave, the Chief Joseph Trail through the Absarokas is fantastic BUT it is high elevation, desolate, winds around, and snows even in summer.
Have fun==I'd envy you but wife and I are going to Alaska in a month!
