CRETAQUARIUM – THALASSOKOSMOS: The extraordinary Aquarium of Crete #1 …

## CRETAquarium Thalassokosmos: a practical visit guide (Gournes, Heraklion)

CRETAquarium Thalassokosmos (often branded as “CRETAquarium”) is part of the Hellenic Centre for Marine Research (HCMR) and sits on the former American Base at Gournes, east of Heraklion.

If you want a Crete activity that’s indoors, educational without being dry, and strongly tied to Mediterranean marine life, this is one of the most straightforward “show up and enjoy it” stops on the island.

## Tickets & on-site extras (official) — and one important discrepancy to note

From the official Fees page, the published entrance pricing is:

– General entrance fee: 8€ / visit (listed with “1/11 – 31/03” on the page)
– Children 0–4: free
– Children 5–17: 6€
– Seniors (65+): 6€
– Individuals with disability: free
– Audio guide devices: 3€
– Virtual Reality experience: 5€

### Outdated-data flag (read this before you publish)
The official homepage shows a different figure for the general entrance fee (it displays 12€ for 1/11–31/03), which conflicts with the official Fees page listing 8€.
Because these are inconsistent, the only fully factual way to write this is: prices may be changing or the site may have a mismatch—verify on the official Fees page before publishing.

## What you’ll see inside: the visit flow and the “don’t-miss” tanks

CRETAquarium describes multiple themed sections and explicitly mentions that visitors will see large tanks (including 600m³ and 400m³ capacity tanks) as part of the “open sea” portion of the route.

### 1) Low-light first section (reef/cave feel)
The aquarium describes an early section with low light conditions, where examples include dusky groupers, red corals, crayfish, gorgonians, and skates.

### 2) “Open Sea” section (big tanks + large species)
This is where the lineup becomes more “big-encounter” oriented. The aquarium specifically references:
– Caretta caretta sea turtle (noting turtles may be temporarily hosted when injured and later released)
– Sandbar shark (Carcharhinus plumbeus)
– Pelagic/open-water species the aquarium says you may have the chance to see, including European seabass and others (listed examples)

### 3) Plankton-focused section
CRETAquarium describes a dedicated section for plankton and plankton-eating organisms, framing plankton as a microscopic “microcosmos” in seawater.

### 4) Coastal ecosystems section
The aquarium describes “coastal areas” biotopes and gives examples of organisms you might notice, including anemones and other coastal-life categories.

### A useful scale indicator
CRETAquarium’s site states: “Sixty two tanks” containing “more than 1,200 marine organisms.”

## How to get to CRETAquarium (bus + logistics)

The official location page states CRETAquarium is connected by bus routes with Heraklion (every 20 minutes in summer and every 30 minutes in winter), and also with the wider Malia–Hersonissos area.

If you’re planning your day around public transit, that frequency detail is the key planning input: you don’t need a perfect schedule; you need the seasonal interval.

—

## Good-to-know services (official)

If you want to make the visit more “guided” without booking a private tour, two add-ons are explicitly listed:
– Audio guide devices (3€)
– Virtual Reality experience (5€)

The site also promotes guided tours and mentions a personal guide option (with conditions), but availability and exact terms can change—treat those as “check current details” items when you’re publishing.

## Suggested internal links (contextual, verify your site URLs)

Because I can’t confirm which RealJourneyTravels.com URLs exist in your install, here are two high-fit internal-link placements you can wire up to your existing slugs:

– After “How to get there” section: link to your Heraklion travel guide (anchor: Heraklion travel guide)
– Near the end (“Plan your day”): link to your Crete itinerary / best things to do in Crete hub (anchor: best things to do in Crete)

## Accuracy & inclusivity notes (what I’m intentionally not claiming)

– I did not claim a summer entrance price because the official pages shown include winter date labeling and also disagree with each other on the winter general ticket number.
– I only described animals and sections that are explicitly listed by the aquarium itself.
– For accessibility-related pricing, I used the aquarium’s stated “Individuals with disability: Free Entrance.”

If you want, paste your preferred internal-link slugs (or your Crete/Heraklion hub URLs) and I’ll drop them into the post so it’s ready to publish without “verify” placeholders.
