The U.S. is a big country so it can be
difficult to recommend sightseeing
locations.　

That said,
I think Yellowstone National Park is
a great place that many people will
enjoy! It's a huge park with parts
in 3 states: Montana, Wyoming and Idaho.　

In the park you can enjoy beautiful
natural scenery like waterfalls and
trees, and wildlife like bears and bison.　

Also Yellowstone has geothermal features
like the famous geyser "Old Faithful"
that erupts every 90 minutes.　

I recommend going at the end of summer,
or even better, in September or October.
The weather is more comfortable and
there aren't so many people.
I hope you can go sometime soon!
