My wife and I were at Poseidon Expeditions trip to Antarctic Peninsula from Dec 30, 2022 to Jan 08, 2023. That was amazing. The ship (M/V Sea Spirit), the crew, the expedition team - everything was perfect.
Our trip was a dream trip.

Outstanding expedition / cruise
Outstanding expedition / cruise. The M/v Sea Spirit is a wonderful boat, small enough to access landing points, at approx. 100 passengers perfect for expeditions and the crew provide great service. The Expedition Staff are outstanding making this trip a lifetime experience.

Poseidon - worth six stars!
If there was a sixth star, Poseidon would get that too!
From the skills, experience and dedication of the entire crew to making my 23-day Antarctica trip, on board the Sea Spirit, so enjoyable, safe and totally memorable, they are now my 'go to' operator when seeking out further cruises!
Forgot about looking anywhere else and just give them a go - you won't be disappointed!

Antarctica - GO!
Antarctica. It evokes an image, for me at any rate, of a wild, desolate, challenging, dangerous place to go. And, having been there, that image is reality - it is all of those things. It is also exciting, rewarding, thrilling, awesome, breath-taking......I've run out of adjectives. All I can really say is - if you have a desire to go and the opportunity - GO, GO GO!! And go with Poseidon! I cannot rate highly enough the enthusiasm, motivation, commitment to both passenger and environment, service, quality and support of the Poseidon team. All the staff, from the deck crew to the 'hotel' staff, to the kitchen and waitstaff and, I guess, especially, the expedition team were only concerned with delivering the ultimate trip for all the passengers - and, most importantly perhaps, without compromising anyone's safety.
Would I go again?
In an instant.
The weather, the scenery, the wildlife, the seas, the wind, the ice, the snow, the zodiac rides, the KAYAKING!! Just unbelievable. The howling gales and storm driven seas for days on end, followed by the tranquil calm and shelter as we moved slowly through an ice field. The falling snow and bitter cold, watching albatrosses soar behind the ship, the looming peaks of the continent in the background, the glaciers hanging over the ocean - these are images I will never forget.
And that's not forgetting the wildlife. Elephant Seals - tons of blubber being moved around at an alarming pace to settle again and appear to fall asleep, the Fur Seal beach masters uttering their challenges, echoing around the cliffs. The juvenile seals sliding through the water, big dark eyes goggling at the invaders. The penguins porpoising through the waves to emerge and stagger drunkenly up sheer slopes, hopping over and falling on obstacles, to join their rookeries, slipping and sliding around but determinedly pushing on. The Albatrosses, Giant Petrels and Cape Petrels hanging behind the ship, sliding through the winds to hover over the deck, curiously checking us out before sliding back down into the slipstream and moving effortlessly past the ship.
And, of course, the kayaking. getting dressed up in thermals, dry suits, life jackets, beanies, muffs, gloves, booties. Getting into the kayaks from the zodiac knowing if you slipped the water was below freezing - and you'd make a fool of yourself! Paddling through pancake ice, then lumps of ice from hand to small table size, past icebergs shimmering green and blue, the water crystal clear, snow falling - the kayaks already covered in white - realising you were quite warm, even when your hands were wet, the kayak balanced and running smoothly, stable and safe. Getting back into the zodiacs and grinning stupidly at the rest of the team, knowing you'd shared something really special.
Memories I will take to my grave.
Go!!

Herzliche Crew, hochkarätiges Expeditionsteam und maritimes Flair auf dem Schiff
Bereits das vierte Mal zog es mich auf dieses kleine maritim gestaltete Schiff. Viele Crew- und Expeditionsteammitglieder der vorherigen Reisen waren wieder an Bord, nach den entbehrungsreichen letzten zwei Jahren ein Gefühl des "nach Hause Kommens". Interessante Tagesprogramme voller Aktivitäten für jedes Sportlerlevel, vielfältige Tierbeobachtungen, spannende Vorträge und das leckere Essen, durch den neuen Chefkoch teilweise auch asiatisch geprägt, machten diese Reise um Spitzbergen wieder zu einem echten Highlight. Eisbären, neugierige Walrösser, einige Wale, eine bunte Vogelwelt und kleinste Pflanzen galt es zu entdecken. Mit dem Kajak-Team erschlossen sich uns die Naturgewalten der kalbenden Gletscher noch intensiver. Aus dem Expeditionsteam besonders hervorzuheben waren Sandra, die Kunsthistorikerin, mit der wir gemeinsam das erste Mal Danskoya (Basislager der Andree-Expedition, mit der sich Sandra wissenschaftlich auseinander gesetzt hat) betreten durften, Page unser Bordfotograf, dem wir wundervolle Fotos verdanken und natürlich Anja, die Seele des Expeditionsteams, die es schaffte uns alle immer wieder in die Kälte raus zu lotsen. Auch die coronabedingt isolierten letzten drei Tage vergingen wie im Fluge, wir wurden in unserer geräumigen Balkonkabine (Deluxe Suite) gut verpflegt und ließen bei einem Blick in die vielfältige Bordliteratur spektakuläre Landschaften an uns vorüber ziehen. Danke der ganzen Schiffsbesatzung für einen unvergesslichen Urlaub.

This was our third trip on Poseidon
This was our third trip on Poseidon. What we like best is the small ship (i.e., fewer passengers that you then get to know better) and the fantastic crew. We also prioritize Poseidon because of the great excursions, usually two per day, out on the zodiacs or on land. Their subject-matter experts are great, covering both natural and human history.

So good, we booked another trip!
We had a wonderful experience on an Arctic expedition with Poseidon. The Sea Spirit is a great boat to be on for a longer trip. The room was spacious, comfortable and nicely decorated. The common rooms were also very comfortable. The dining room offered a good variety of food for all meals and was tasty. Probably the thing we liked best was the service - from ALL the staff on the ship. The service was faultless, from the person who cleaned our room, the servers in the dining area, the reception staff, and those in more background roles, such as the ones who helped us in and out of the zodiacs. The expedition team was very knowledgeable, and also very service-oriented. The only suggestion we have for improvement is better clarification in brochure materials of what you can expect as part of the expedition. We had expected to see more wildlife than we did, and even went back to the brochure to see if we had misread it (we had not). Our cruise was more a “scenery” cruise, which was beautiful, but we would have liked to have the correct expectations going in. That said, we highly recommend Poseidon, so much so that we have booked another trip with them for next year.
