Miramare Castle

Feel free to explore at your own pace and discover

Stop: 3 hours - admission not included

The eclectic castle, often characterized by its “white towers”, was built for Archduke Maximilian (the future emperor of Mexico) and his wife Charlotte in 1860. After a brief reign as emperor of Mexico, he was tragically shot and killed. His wife Charlotte went insane after the Archduke’s death, spending her remaining years in seclusion. From this tragic tale was born a legend that anyone who sleeps in Miramore Castle is fated to die a violent death at a young age and in a foreign land. Today, the historically rich castle is open to the public. A huge botanical park, made up of exotic trees, surrounds the grounds. Walk freely through the beautiful garden and around the castle grounds. For a fee, it’s also possible to tour the interiors of the castle with its preserved original furnishings. There is also a museum with a bookshop and a bar in the garden to enjoy the scenery.

Postojna Cave

Feel free to explore at your own pace and discover

Stop: 3 hours - admission not included

Postojna is a 24,120m long cave in southwestern Slovenia, making it the second longest cave in the country. The cave is a 24-kilometer network of passages, galleries, and chambers. Begin your visit aboard the cave train, which takes you on a 2-kilometer ride deep into the caves. After the ride, you’ll go comfortably on foot to explore more of the caves. Electric lighting allows you to take in all the splendor of the towering limestone formations. Guided tours are available and last approx. 1.5 hours. Audio guides are also available in 15 different languages.

Great transfer option.

I used this service for a transfer from Split in Croatia to Perast Montenegro. My experience was exceptional. My driver Bojan was helpful, informative and ensured my journey was comfortable and enjoyable. I highly recommend the service.

It was a fantastic trip.

We were extremely satisfied with the quality of service we received from Day Trip. We had two Day Trip rides on August 31 from Athens to Lefkada and September 7 from Lefkada back to Athens. Both trips included stops at scenic sites in Greece. Both drivers were excellent and accommodating. However, we’d especially like to recognize Panos Peppas, who was our driver from Lefkada to Athens. Panos was incredibly nice & pleasant and delivered outstanding customer service, which included handling all of luggage, providing us with cold waters throughout the trip, providing us protein bars, providing us with printed materials on the Corinth Canal (one of scenic stops), looking up and providing us with terminal & gate info for our flight back home and providing us with a recipe for tzatziki.

Best transport company anywhere

We absolutely love this company and have used it many times over the years to get from A to B without the hassle of hiring a car ourselves. Excellent drivers every time. Efficient and professional. It’s worth every penny and we can honestly recommend Day Trip to everyone. It’s 5 star rating is well deserved.

Excellent experience in traveling

We traveled from Nuremberg to Munich in a beautiful Audi. Driver picked us at our hotel at the exact time requested. Got us to Munich in plenty of time for our next tour. Driver made sure we were comfortable

Reasonably Priced and Safe Transportation

Gonzalo from daytrip was our driver and he was absolutely amazing. He went over and beyond trying to locate us as our service wasn't so good on our phones. He patiently awaited our arrival to the lobby so he could take us from Tulum Dreams Resort to our other hotel in cancun an hour and a half away near the airport prior to our departure flight home. He was polite, respectful and kind. Made sure we were comfortable during our long ride. Fast and to the point. I recommend this company as finding a one way ride from Tulum to Cancun isn't easy or cheap and this company provides a great service for a great price. I will definitely be using them again whenever I'm in the Cancun/Tulum area. Thank you DayTrip and Gonzola.

Daytrip never disappoints

We were picked up by Marianna to drive us from Heraklion to Chania. The weather was terrible & due to this Marianna arrived a few minutes late. She contacted me to advise of this. Marianna lives in Chana and she made our trip very interesting by informing us of local things to do and see in Chania. Marianna is a safe driver and we all felt comfortable with the speed she drove at and how good her driving was in heavy rain. She is a lovely person with fluent English. We highly recommend Daytrips and if you are in Heraklion or Chania please make sure you ask for Marianna.

Great driver in Egypt

Used the service to go from Luxor to Hurghada, Egypt. Ahmed H was our driver and he was perfect. The car was new, clean, he had water and snacks for us, and accommodated our stops. Great service from him and would recommend it.

Comfortable and Safe Rides in Mexico

Used Daytrip for two rides in Mexico, which were both great. So comfortable, and we arrived at each of our destinations at a great time. Both were incredible drivers, and we felt so safe. One of our drivers, Miguel, also played the best music! Will definitely use Daytrip on our next trip to Mexico.

Great way to travel and see some sights on the way

We did not know what to expect with this trip and booked from Australia. We were initially looking for an easy way to travel from Granada to Malaga. We decided not to waste the opportunity to see something additional on our way. Miguel certainly exceeded our expectations. His English was excellent (unfortunately we speak very little Spanish), and he was very friendly and helpful. We thoroughly enjoyed hearing about the regions as we passed through and also discussing some of the local ways. Miguel took us to Antequera as planned and ensured we were able to easily get our tickets to the attractions without any sense of rushing us. We were picked up and dropped off punctually and really enjoyed our trip. Hopefully we will return to Spain and we can use this service again sometime.

Excellent service

We used the service twice while in Thailand. Extremely prompt and efficient customer service. Best rate being offered in Chiang Mai for the travels. Polite, punctual, professional and English speaking drivers. Clean, comfortable vehicles. Being a regular visitor to Thailand, this was hands down the best service. Most pleased with the company. I hope it sustains the excellence of service that was rendered to us.
