A LONDON STREET
At first it looks like you are walking down a regular street in London.
Then you come across the Knight Bus.
You also happen to pass by Grimmauld Place.
You can also check out the phone booth a.k.a. the secret entrance to the Ministry of Magic.
DIAGON ALLEY
For me the most magical part of the day was exploring behind a regular looking brick wall and then walking into this!
Diagon Alley is a completely immersive environment that makes you feel as if you are walking into the scene in the movie when Harry sees the magical world for the first time. The details on every shop and storefront were amazing.

The window displays magically moved. The kids are watching a scarf knit itself.
Buying a chocolate frog and Bertie Bott's Every Flavour Beans. The jelly beans were fun to eat while we stood in line and the kids made guesses about what flavor they ate. True to the story, there were normal ones, but also earthworm (tasted like dirt), rotten eggs, etc.
The Leaky Cauldron
Weasley's Wizard Wheezes

Olivander's wand shop

Quality Quidditch supplies




Magical Menagerie was Audrey's favorite shop. She liked all the stuffed animals and ended up with a purple pygmy puff.
The dragon on top of Gringotts Bank took us off guard by periodically growling and sometimes letting out a huge burst of flame.
Gringott's bank
Our favorite ride of the day was Escape From Gringotts. It is a 3D roller coaster that took you on a run away ride through the vaults at Gringotts.
Hagrid's motorcycle


Wiseacres Wizarding Equipment
Norberta, our baby dragon.
THE HOGWART'S EXPRESS

The station
Platform 9 3/4


Boarding the train felt like you were just getting onto the actual train on your way to Hogwarts.

The screen outside the window made you feel as if you were traveling out of London into the countryside, just like the train does in the movies.

Unfortunately our train was attacked by some Dementors.
The train and its conductor.
Hogsmead Station
HOGWART'S CASTLE
The Forbidden Journey ride was amazing, although it made me a bit sick. We didn't mind the wait in line because it took us through different places in Hogwarts castle (the hall of portraits, the green houses, entrance to Dumbledoor's office, the mirror of Erised, etc.)

Hagrid's Hut
Audrey was super excited to go on Flight of the Hippogriff. It was her first big roller coaster. I was worried that she would be scared, but she told me she loved it!
I think this was our family's favorite day of the trip.
