Siena Mueller

Whether you're a solo adventurer, a couple seeking romance, or a family craving new adventures, I'm here to tailor-make your journey, ensuring it surpasses your expectations while contributing positively to the local community. From scenic nature activities to deep dives into history, culture, and cuisine, I'm passionate about sharing my love for travel with all types of adventurers.

What places and activities do you specialize in?

"I specialize in crafting tailored trip plans for solo travelers, couples, and families, catering to newcomers and experienced travelers looking for a new adventure. My favorite activities include scenic nature adventures and immersive experiences in history, culture, and cuisine."

How did you get involved in travel?

"Guided by my family's adventurous spirit, my introduction to travel began at an early age. My mom prioritized taking my sister and me on yearly trips to new places throughout my childhood, from local road trips to flights across seas. These experiences sparked my love for exploration, paving the way for my pursuit of a Bachelor's Degree in Sustainable Tourism Development. During a study abroad program in Greece, focused on community development and tourism in the Mani peninsula, I fell in love with the country's rich culture and gorgeous landscape. With 20 countries under my belt, each journey adding to my wealth of experiences, I continue to be inspired by the transformative power of travel."

Please share a unique travel experience you will never forget.

"I have been so lucky to have had many impactful travel experiences - my pro tip is to keep a travel journal to help you remember the details of your adventures! One particular adventure stands out: a hike from Milia to the Panagia Giatrissa Monastery. Trekking through lush green mountains, we discovered hidden creeks and funky insects. We finally reached the top, after getting beautifully lost for an additional mile or so, and soaked in the inspiring view of the mountain range. There, a clergy member shared the land’s deep-rooted history over Turkish coffee. Returning to Milia, we shared a meal with locals, tasting some of the finest olive oil and exchanging stories that bridged generations. This experience perfectly encapsulates my approach to travel: a harmonious blend of nature exploration and cultural immersion, connecting with locals who enrich our understanding of the places we visit."

Our only regret was staying in Airlie Beach rather than on Hamilton Island. While Airlie and our accommodation were lovely, we underestimated how far it is from the most scenic parts of the Whitsundays. With limited time, we wish we’d paid extra to stay on one of the islands. We’d recommend future travellers stay directly on a Whitsundays island if possible.

Thank you so much for your thoughtful review Katie! I'm so happy to hear your holiday trip to northern Queensland trip was a success. We also really appreciate your feedback about Airlie Beach versus staying on one of the Whitsundays islands. You’re absolutely right that, with limited time, being based directly on an island can make it easier to soak in those iconic landscapes.

From start to finish our trip to Greece was flawless. Our specialist, Sienna crafted the trip of a lifetime…all within our budget. The communication was superb. All of the boutique hotels were unique and catered to our every need. I felt like a rockstar when transported by our drivers in luxury vans . They provided a lot of local color and could not have been more kind while driving us to our incredible tours. Each tour guide holds a special place in my heart. Their knowledge and love for their country was an experience I will never forget. Five stars is not enough! Truly, a trip of a lifetime

Arion Athens Hotel
Athens

The location of the hotel made it convenient to walk to restaurants and shops. The streets are narrow and double parked so that made it difficult for taxis or drivers to be able to pull up right to the door, but it was usually just short walk up the street to the main road. We took advantage of the 7th floor terrace and enjoyed the Acropolis views from our balcony!

Mycenae was very interesting to walk through and imagine how it was so long ago.

We loved Nafplio but our time there seemed rushed in order to get back on schedule.

Thank you Siena for planning an amazing trip for us. This was my first time ever to Australia and I can’t wait to go back and see more. Everything worked out perfectly all our drivers were on time and accommodations were great.

Just wanted to give you guys a heads up on the day we arrived at Pinnacle, we did have an issue trying to check in because it was a holiday there. Our driver that day was amazing. My phone wouldn’t reach out to them, and he personally dialed the number, so I was able to upload what they needed and get into their key box. He also helped with our luggage. I can’t complement him enough. What would have been a stressful situation was resolved because of him.

The only other suggestion would be to not spend so much time in the airport. I think on three occasions we were there for three hours. Especially when it’s a small airport we couldn’t even check in at one until an hour before.

Thank you again sienna for an amazing experience. We would definitely use you again. Everything was so great.
