Authors note: First thank you all for the reviews! I didn't expect positive feedback to be honest. English is not my mother tongue and I really try hard to not disappoint native speakers. Also this is my very first writing project so I am glad if I receive feedback.
Some people doubt that Molly and the Order would let the three go on the trip. I agree! There is a good reason but it will not be revealed yet :P

Somewhere in southern France a white camper was driving on a narrow road meandering along a beautiful coast line. The sun had still not risen and no bird was yet awake to announce the beginning of the day.
The only thing Emilia could hear was the humming of the engine paired with the sound of the waves. She felt like in a trance, listening to the music of nature and enjoying the wind blowing on her face through the open window.
At some point she wondered how she drove the last few miles. Did she pay attention to all the street signs? Emilia seriously couldn't tell but was optimistic that her subconscious did everything right.
Finally they reached their first destination. Turning left, a gravel path was leading to a small camping area that she had seen on the internet. She didn't have trouble finding a parking space, the place was basically deserted. Just one other tent was standing on the opposite side of the space.
The sea was only a few hundred meters away, but barely visible from the campsite. A wall of high rocks was standing between. On the other side towards the main road, a little hill covered with trees and bushes was protecting against unwanted looks.

Harry, Ron and Hermione were still asleep in the camper. They basically slept during the whole drive. She was hoping that they would at least take care of the rest, like preparing breakfast and making fire.
After exploring the surroundings for a few minutes, Emilia returned to the vehicle and climbed in the back. The camper was not particularly well equipped. When her friends rented it, they searched for a cheap model that some young adults could afford.
They had one double sized bed, a small sink and luckily a toilet. She was definitely not looking forward to empty the tanks and was thinking about transferring the task to Ron or Harry.
Hermione and Harry were lying in bed, while Ron was sleeping in his seat. He had offered to join Emilia in the front. Though it was a nice gesture of him, he clearly had missed the opportunity to get a restful sleep. Harry and Hermione looked deeply relaxed, and they didn't even notice when Emilia decided to join them in bed.
There wasn't much space left between them when she was lying on the other side of Harry and quite a few moans were hearable when she demanded her piece of the blanket.

Clonk – Clonk - Clonk

"WAKE UP EVERYONE, BREAKFAST IS READY", Hermione shouted through the camper while hitting a silvery pot with a spoon.

Clonk – Clonk – Clonk

"BLOODY HELL Hermione, stop it", Ron cried from the front.

Clonk – Clonk – Clonk

"HERMIONE! Your noise would wake up squirrels from their hibernation even a few miles away. If it was winter"

Harry and Emilia started laughing at that comment but Hermione just replied,
"Then stop your winter sleep Mr. Weasley and get up. It's so beautiful out here"

They jumped out of the bed and seat respectively and started to get dressed. Harry couldn't resist to take a quick glance at Emilia before she took on her shirt. His cheeks flushed visibly at the sight of her exposed body. The quick glance turned into a rather long creepy stare. Luckily her back was turned to him.
Hermione had already prepared scrambled eggs, some bacon and cereals which Ron eyed suspiciously. They sat around the small fire Hermione made for the cooking, and thanked her for breakfast. For a minute they all enjoyed the silence in their camping chairs.

"It's so beautiful here, you can't see the ocean but you can clearly hear it", Harry started the conversation.

"It is, and we are basically alone here, except for the people over there", Hermione added, pointing at the tent.

"Ah, don't worry about them", Ron said smilingly. "I am pretty sure they are some nice blokes. Thank you Emilia for driving all the way here!"

Harry and Hermione thanked her too and when Emilia was finished with her bowl of cereals she said,

"I have something in mind for today. I am not forcing you to join or anything but it was always a dream of mine"

When the others just looked at her curiously but didn't say anything, she continued.
"You can't see the ocean from here, but when you are on top of rocks, you actually have a pretty nice view over the whole region. I saw some picture on the internet, it looks incredible"

"Emilia, I am pretty sure nobody will be offended by a little hike", Hermine said, smiling at her.

"Well, the problem is, there is no trail"

"Ehh - How do you mean? How are we supposed to get up then?"

"Just use magic, a little levitation charm will do", Ron jokingly interrupted them.

"Don't be silly", Emilia replied. "We climb up!"

"Excuse me?", Hermione squeaked.

"I did take my rock climbing gear with me. The rock is not that steep and high, you can all do it. I will show you the basics and we can climb safely up"

Harry and Ron looked at each other being not sure how to react to her suggestion.
"Ehhh – are you sure that we are the right people for such kind of adventure?", Harry asked her carefully.

Emilia eyed Harry for a moment, examining his shape. She then reached for his fore and upper arm and squeezed both with her thumb and index finger.

"What are you talking about, you seem to be in a good shape"
"Well – I don't know. I – but I guess I will be in if you think I can do it. You are the expert", Harry replied shyly, his cheeks reddening again.

"Me too! It will be a lot of fun, won't it?", Ron said confidently, smiling at her.

Hermione shook her head vigorously, muttering something about boys and hormones.
Emilia didn't notice her doing that, but then she turned towards her and asked,

"What about you Hermione? Come on, it's going to be fun. I will teach you everything, the route is really easy"

"Sure", Hermione replied shortly clearly not sounding too eager about the climbing. She then stood up quickly and picked up the dishes from the others.

"I will take care of the cleaning", she noted and vanished in the camper.

The remaining three shared a knowing look but only after a few seconds Emilia dared to ask the others,
"Is Hermione afraid of heights?"

"Yeah I think so, she would never play Quidd – outsch! I mean she would never go flying with us when we asked her", Ron answered a bit too truthfully.

"How do you mean, fly with you?", Emilia wanted to know.

"Oh like a small plane you know, we have a field near our school where you can get your license", Harry lied helping his friend.
He tried to warn Ron by kicking his leg, which worked but now he had to come up with a fake story.

"That sounds really exciting. I will talk to her, we can do something else. It's no problem for me" With that she rose from her chair and walked towards the vehicle.

"Ron – you have to be careful, she must not find out"

"I know, I am sorry mate. It's hard for me not to talk as usual. You are familiar with being around muggles. I am still a novice"

They shared a good laugh. Harry hoped that Ron would take it seriously though. A little mistake and Emilia would start to ask questions. They knew that sooner or later she would notice something but they wanted to delay that moment as long as possible.

"Are you really that excited about going climbing?", Harry asked his best friend.

"Not really, but I thought that we should let her take the lead a bit. I mean I have no idea what muggles do in their free time, but rock climbing doesn't sound too bad. I mean I prefer brooms of course, but a little workout will not harm I suppose"

"You don't really sound convinced"

"Because I am not. I happily volunteer to put my life at danger for muggle wizard exchange"

"Well not even that, she doesn't know that we can do magic. It is a one sided exchange at least"

They laughed again. Just when they wanted to start talking again, two figures approached them.

"I am sorry that I was a bit – ehm – harsh", Hermione began. "I would be really happy to go climbing with you"

Surprisingly her face matched to her words, not showing any fear or doubt that has been on it a few minutes before. Harry wondered whether Emilia was a witch after all, persuading her that quickly. Maybe she used the Imperius Curse on Hermione to force her. Life sentence in Askaban but went climbing before – worth it!

"What's so funny, Harry?" Hermione asked him suspiciously.

"Nothing, nothing. I am just really happy that you come along"

"Sounds good to me", Emilia said and beaming at them. "Thank you so much, It will be a lot of fun, I promise"

After breakfast they first explored the region a bit. There was actually a short track from the campsite to the water. A small crack between two rocks led to a small cave. One could get in the water there and then swim a few metres to get to the beach. They didn't try it out though, the water was really cold and they wanted to wait until it was warmer.
As their little exploration came to an end, Emilia started to show the others how to use the climbing gear.

"This is the belaying device", she told Ron who looked at it, clearly not understanding how this little thing should help to belay anything.

"The person on the ground will use it belay his or her partner who will climb. It basically works like a hoist. If the person climbing falls you will be pushed upwards. We should make sure that the partners have about the same weight"

She explained more things, like making the knot who looked like an eight or how lead climbing works. Hermione, Ron and Harry felt more confident after Emilia finished teaching them. At least they understood now how the principles work.

When they reached the starting point of the climbing route their initial calmness quickly turned into fear. Emilia was the first to go. Hermione wore the other climbing harness and belayed her.
As she reached the top, Harry and Ron awoke from their trance. They had been staring at Emilia the way up.

"Wuhuuu, it's so nice up here! Come on, it is your turn", Emilia exclaimed happily throwing down the equipment to the others.
The trio didn't respond immediately, uncertainty in their looks. Ron's legs were starting to shiver noticeably and Harry didn't look better. His face was pale and he began scratching his head awkwardly. After a few seconds though, Ron was ready to climb with Hermione belaying him.

After several minutes everyone reached the top of the rock safely. The last one to climb up was Hermione and when she saw the view over the sea, she let out a sigh of relief.

"This view is amazing, Emilia", Hermione said while her eyes were still focused on the horizon.

"I know, we are just a few feet above the ground though. Sometimes a small change in perspective leads to a big change in thoughts". She smiled.

"Wise word have been spoken", Harry commented nonchalantly.

They all laughed about the comment and tried to find comfortable positions to sit. Harry was next to Hermione when she spoke in a whisper to him.

"I wish we could stay here forever"

The boy who lived smiled at her.

"Here? Sitting on a rock, staring at the sea and doing nothing? My arse already has several dents because of the stones beneath it" He chuckled.

"Hmpf, better dents in your arse, than a killing curse in your chest", she replied. Her voice hardly but noticeably shaking.

"Hermione, don't worry about us, we will be fine. We are safe here and will be safe when we return to Hogwarts"

"How can you …"

"What are you guys talking about?" Emilia was standing right behind them, and had obviously tried to overhear their conversation.

"Oh nothing", Harry said. "We were just discussing how truly magical this place is"
