It's a bit of a cop out as most have been covered in their own 7 wonders of but I have to put down my favourite things of THIS trip to the USA and these were it
1/Bryce Canyon (see My 7 wonders in and around Vegas)
2/Niagara Falls comprises of three waterfalls, the Horseshoe Falls, the Bridal Veil Falls and the American Falls. The Niagara Falls park is about 27kms north north west of Buffalo and about 6 and a half hour driving time from New York, through some very picturesque countryside especially in winter, The falls are stunning in winter, with half of them in heavy ice, so I am hoping I get a chance to see them again when they are in full force
Getting to Niagara is dependent on whether you are coming from the Canadian or American side. We started our trip in New York and booked through Viator and it cost us $315 for a 2 day tour including hotel which we thought was great.
3/New York (see My 7 wonders of New York)
4/Disney (see My 7 wonders of California)
5/Grand Canyon (see My 7 wonders in and around Vegas)
6/San Diego Zoo (see My 7 wonders of California)
7/Santa Monica Beach and Pier-after what felt like forever on a plane it was wonderful to take in the sea breezes, to see the wide expanse of water and just enjoy, and the cheapest of adventures.....just a $2US bus trip from the airport
