I think I would like to experience Lucy's first discovery of Narnia! I always loved that part in the book (and movie). I think it would be great to experience that awe and wonder from finding snow in the back of a wardrobe And of course, seeing the lamppost, meeting Mr. Tumnus, having tea with Mr. Tumnus...ahhh it would be great

The time when Lucy went to find the spell book in the Magician's mansion. I like anything mysterious which is why I chose this scene from the book.

I would definitely want to experience the Voyage of the Dawn Treader sailing in too the unknown and seeing the things at the end of the world would be truely amazing.

Difficult choice. The Voyage of the Dawn Treader is tempting but I have a bit of a phobia concerning boats - not quite as bad as Eustace (the Isle of Wight ferry is no problem at all) but weeks or even months on a sailing ship would be a bit much. The Magician's Nephew... I'd be fascinated with all the inter-dimensional travel, plus the creation of a world. Maybe I'd be a bit too much like Uncle Andrew for my own good. The Last Battle - experiencing travelling into ever-more-real Narnias would be mind-blowing.

But I think I'll go for The Horse And His Boy. Difficult, dangerous, but the rewards so much outweigh the hardships.

Much as I would like the VDT storyline, having actually seen that lovely boat, which was used in Walden's filming, and stood on its deck, I really would prefer the storyline of HHB.

Spending time with a horse that could talk, or even any animal that could talk, though I might not always like what I hear. Riding to Tashbaan and beyond on a mission, across the desert, to be received by King Lune as a most appropriate and worthy messenger whose message saves the day. And most of all, to meet Aslan on the mountain top in that wonderful scene where he proclaims that he was with Shasta all along. And Aravis as well.

I notice that no one has even considered The Silver Chair. Poor Jill, Eustace and Puddleglum.

I've always had difficulty with this question because a number of them tempt me for various reasons, but I think I'll go with The Horse and His Boy. Plenty of natural beauty to take in while traveling through different types of terrain, and I think the court of Archenland would suit me well. I also haven't ridden a horse in a very long time and rather miss it. Being able to talk with one would be amazing!

Either where Lucy first enters Narnia (LWW) or where Shasta meets Bree (HHB)... I have a craving for adventure and discovering new places. And if I could turn around and have a horse talk to me that would be awesome! XD (Maybe not the whole about to be sold into slavery part, but they made it out okay in the end, right? )

I would love to be riding with Shasta in HHB, mainly the part where he is walking beside Aslan. That whole scene gets me every time. Or the first time he hears Bree talk to him. Oh to see his face would be perfect.

I think I would love to be apart of all the adventures that the Pevensies had as Kings and Queens. We only had a glimpse in HHB when they are talking about Peter battling the giants of the giants of the north and I can’t imagine all the adventures they are went on.

I would most likely want to go on the quest in the Silver Chair. The idea of journeying into bleak Northern Mountains on a mysterious mission is kind of, well, thrilling! (And getting to carry swords and bows kind of appeals to me as well. )
And what boy hasn't wished himself in Peter's shoes in the LWW? Being made a knight, a general and a king in the space of a few days, while fighting and winning a battle... it doesn't get much cooler than that.

Probably when All the pevencies see the real Narnia in the last battle.

Probably seeing the creation of Narnia.
Secondly, meeting Puddleglum and travelling across the landscape with him.

These are only parts of adventures. Other parts I would like are those where a new arrival in Narnia meets several of the non-human residents for the first time (eg Caspian or Shasta),

I would do The Magician's Nephew. The main characters have the least harrowing journey. They don't have to cross an ocean or a desert or a giant-inhabited moor. They don't have to fight anything physically. And they get to fly on a horse and see Narnia coming to life. The dying mother thing would be kind of a downer though...

The sea voyage in Voyage of the Dawn Treader was always the most interesting Narnia experience for me. I would love to live that adventure in real life. The experience was probably the best seen through through Lucy Pevensie's eyes, but if you are a man like me it would be great to be King Caspian too. Of course Eustace had a better attitude after he changed, but he missed much of what was great in the voyage by causing problems for everyone else. He did have a really good encounter with Aslan. I think for me the Dawn Treader (both the ship and the book) was like a dream come true.
