Tulsa is in a very wooded, hilly area. We've had a lot of rain and everything should be very green. The old part of town is nice although lately some parts seem a bit rundown. The suburban areas are just like in any other city. If you like architecture, there are some interesting buildings downtown, especially the Boston Avenue Methodist Church. It's just magnificent.
Oklahoma changes dramatically from east to west and Tulsa is still in the Eastern woodlands part of the state. Highway 412 east from Tulsa is a beautiful road all the way to the Arkansas border at Siloam Springs. Be sure to take the older highway. The new turnpike is faster but not nearly as interesting. If you get as far as West Siloam Springs, I would want to go to
Natural Falls State Park. I just recently found out about this place and have not yet been able to go but it has been highly recommended to me.
Great Salt Plains State Park is west of Tulsa. The salt plains is weird; almost a moonscape. But the area around it is nice and it's one of the best places in the country to find migratory birds, even pelicans and no ocean at hand!
If you keep going west on 412 it'll start looking very "old western", but that's a long drive from Tulsa.
It's only a short drive east to Muskcogee which is a nice town to visit. In that area you could see Fort Gibson lake and visit the old stockade style fort as well as a trip to the old Cherokee capitol of Tahlequah. Lots of historical and Native American things in that part of the state, if that's of interest.
There are lots of other places, check the department of tourism
OK State Parks or check with some locals in Tulsa.
Sorry this post is so long. Hope you enjoy your trip.
