Travel & Adventure

Travelling from the UK to a Greek Island without flying...

The Carbon Jacked Greek Odyssey

Published 6/3/2022

Firstly, why…

As imperfect environmentalists, we’re all about finding creative ways to combat climate change, reduce our impact on the planet and have a bit of fun along the way.

For us, there’s no point trying to save the planet if you never see it, but you can’t escape the fact that travel causes emissions that we need to find ways to massively reduce. The solution isn’t to stop travelling altogether, it’s to travel better.

Until aviation sorts itself out, one of the best ways to do this is to use alternatives to flying when you can, so we thought we’d have a pop at an elaborate journey to show you the highs, the lows and what this means for your carbon footprint.

The Route and The Results

A map of our nature positive journey to Naxos

3 trains, 2 ferries, 1 coach

  1. London > Paris | Eurostar train | £103
  2. Paris > Milan | Train | £70.25
  3. Milan > Bari | Train | £60.99
  4. Bari > Patras | Overnight ferry | £53.41
  5. Patras > Athens | Coach | £15.93
  6. Athens > Naxos | Ferry | £53.68


  1. Our journey - 27.65kg of CO2e per person
  2. Flying - 405.83kg of CO2e per person


  1. Our journey - 6 days (inc. overnight stops in Bari and Athens)*
  2. Flying – 1 day

*We stayed overnight in Bari and Athens, but you can do the journey in 3 days.

Transport costs

  1. Our journey - £357.26 (excluding hotel stays)
  2. Flying – approx. £176 per person

So our transport costs were approx £181 more than if you flew.

Was it worth it?

Yes, with caveats….

Long story short – travelling without flying is better for the planet. In fact, flying to Greece would’ve caused over 14 times more emissions. That said our journey definitely cost more and, unsurprisingly, took a lot longer, but it made for a pretty epic adventure.

️We know it’s not always feasible to avoid flying, and there are major cost / time considerations, but we wanted to show that it is possible. Going from the UK to Greece is obviously somewhat at the extreme end, but there are lots of journeys where it’s much more feasible to avoid flying and the price isn’t hugely different either. For example, you can get to Barcelona in a day from the UK via trains.

07:40 - Leave hotel for Milan’s splendacious Centrale train station 🚉

07:50 – Curtis gets second coffee of the day

08:05 - Train from Milan to Bari - “The. Best. Train. Ever. Seriously.” According to Jacques (and that’s the abridged quote). Tbf the coastline views were particularly serene 🛤

14:00 – The Jacks run the gauntlet along the many many carriages to procure another coffee after a heated debate with the barman mostly done via gesticulation ☕️

17:00 – Chase the last remnants of the sun around Bari 🏃🏽‍♀️🏃🏽‍♂️🏃‍♂️

*Timings May vary

Stats for the day: 8 hours of travel time, 785km, 1 train, 7 coffees, 17.5% wine, 19,329 steps.

Lowlight: Train WiFi was a bit dodgy and Curtis’ alarm is a simply unacceptable sound.

Day 3 & 4 – Bari to Athens

AM – Eat, Love, Pray in Bari (actually mainly spent working) 🇮🇹

17:30 – Frantic march to the port while dodging numerous cars and lorries

19:10 – Glory strikes as we secure cold beers on the helipad for departure 🍻

20:00 – 23:00 – A slightly exhausted session catching up on work

23:30 – Scout out alternative sleeping arrangements and set up camp 🏕

00:00 – Bed down

04:00 – Pandemonium and aggressive alarms ensue as the ferry stops at Igoumenitsa and most of the passengers, particularly the drunk ones, disembark. Jacques sleeps through. 😴

06:00 – Jess awakes to glorious sunshine and Greek islands on the horizon. 🌅 She goes for coffee and a restorative reading session. 📖

07:00 – Team CJ set up shop at the stern of the ship for some early morning work 👨🏽‍💻

12:00 – Arrive in Patras, our planned transfer bus no longer exists…

12:10 – Taxi driver gets aggressively angry at the concept of us sharing a taxi with another lone traveller, but we make light of his undue rage and bring the gentleman along for the ride 🚖

12:45 – Splendid coach journey to Athens, although Athens bus station was, as per, found wanting… 🚏

16:00 – Arrive in Athens. Known for many things - democracy, the Olympics and now most famously a pitstop on the CJ Odyssey. 🏛

Stats for the day: 1 ferry, 1 coach, 787km, 0 discos, 0 swimming pools, limited hours of sleep. 

Highlight: Morning on the ferry – sunrise, coffee and contemplative reading.

Lowlight: The lack of a 24-hour disco on the ferry.

Day 5 & 6 – Athens and onwards to Naxos

Day 5 - Athens

AM - went something like work, coffee, work, coffee, work ☕️

PM – exploration and discovery 🎒

- Lacklustre jog (the cumulative tiredness was really starting to take hold at this point). Found a great viewing point of the city mind you 🌇

- The alternative tour of the Acropolis with renegade tour guide @jess__rogers. Glorious views and many, many facts (some of them hopefully true) 🏛

- Much-needed sustenance

Day 6

03.00 – 05.00 – Jack woken even earlier than usual by frankly riotous preparations for the day's flea market 🫒 (the olives looked damn good mind you)

07.01 – 10.59 – work, coffee, work, coffee 👨🏽‍💻

Stats for the day: 1 ferry, 176km, 1 Acropolis, 12 or 13 gods. Gale force winds.

Highlight: 'Obviously the tour of the Acropolis' (and the Athens coffee scene)

Lowlight: Why do you need to start setting up for a market at 3am??
