National Marine Aquarium, Plymouth

What better place to go when you want to dodge the rain than under the sea? OK, not really. But the National Marine Aquarium in Plymouth is the next best thing and holds the rather impressive title of being the largest aquarium in the UK.

Not only is the NMA a top place to go on a wet day in Devon, it’s also open all year round giving you an easy option to entertain your family whatever the season. Oh, and visit once and you have free reentry for a whole 12 months! Jawsome!! #Sorry

So, if you fancy immersing yourself in Devon’s marine world, here’s my guide to visiting the National Marine Aquarium in Plymouth.

About Plymouth’s aquarium

The National Marine Aquarium is one of those places you could keep going back to again and again. I’ve lost count of the number of times we’ve been to this charity-run attraction.

The enormous tanks showcase species from UK waters, as well as the Atlantic Ocean and Great Barrier Reef, and are changing all the time. That’s not to mention a calendar packed with events to coincide with school holidays.

The Ocean Conservation Trust team here did some amazing online events during lockdown. I’m sure they helped out a lot of families struggling with home learning by broadcasting mermaid tales and marine wildlife talks over the internet.

This content is all still available on their YouTube Channel and is fun viewing ahead of in-person visits that are now possible again.

Things to see and do at the National Marine Aquarium

Here’s some of the things you can see and do at the National Marine Aquarium in Plymouth:

The UK’s deepest aquarium tank

Take a seat in front of the glass of this gigantic curved window into the UK’s deepest and largest aquarium tank. At times it’s up for debate who was watching who.

The giant sting rays glide across the glass, while the sharks slide cooly through the water seemingly observing you with their beady eyes. You might also spot ‘Friday’ the Green Turtle.

Interactive exhibits

There’s just the right balance of interactive exhibits to go along with the huge tanks where you observe the sea life.

There are bulbous windows that allow children to listen to the sounds of the ocean inside and interactive displays that teach you about the important role of sea grass in the underwater ecosystem.

There’s plenty of steps and blocks for young children to stand on so they can see into tanks and get a good view of feeding times.


As well as wandering around the UK’s largest aquarium at your own pace you can also see several daily shows and talks.

If you have older kids then I’d recommend trying to plan these into your day to get the most out of your experience. You can find out the timings for these in advance by taking a look at the aquarium’s website.

Be aware that talks have been scaled back during the pandemic but there are still plenty of Ocean Discovery Rangers around who are happy to answer questions.

Find out even more about the four ocean zones and everything there is to do on the National Marine Aquarium’s website.

Handy things to know

Here’s some more handy things to know ahead of visiting:

How long do you need to visit the National Marine Aquarium?

We have visited a several times and spent different periods of time looking around ranging from an hour to three. It all depends on our kids’ attention spans on the day and whether there are other activities happening.

The good thing is you have the option to visit again for free if you do whistle around.

Does Plymouth Aquarium have sharks?

Yes, it has a few. You can see Sandbar Sharks, Nurse Sharks, Sand Tiger Sharks and Zebra Sharks. Don’t miss the Demi-Tunnel where you can see the sharks swimming past and above you.

Facilities at the aquarium

The aquarium has its own cafe. This is situated on the first floor of the aquarium and has panoramic views out over Sutton Harbour, the Barbican and Plymouth Sound. It’s a great location. There’s plenty of child-friendly snacks and meal options.

The aquarium is pushchair and wheelchair accessible. Where there’s no a ramp between levels there is a lift. Find out more about accessibility at the NMA.

Where is the National Marine Aquarium?

You’ll spot brown signs pointing you in the direction of the aquarium all around Plymouth. Here’s where to find it:

National Marine Aquarium parking

The aquarium is right beside Sutton Harbour and does not have its own car park. The closest place to park is Harbour Car Park: 1 Lockyers Quay, Plymouth PL4 0RA. This is a short walk away. It is a pay and display car park that accepts cash or card.

The aquarium recommends that you allow up to three hours parking for a visit.

National Marine Aquarium prices

It’s recommended that you book your tickets and arrival time online in advance of your visit as the aquarium has limited capacity. It is particularly busy on wet days.

There are two tickets price tiers depending on the time of year you make your initial visit.

Whenever you visit your ticket is then valid for revisiting for free as many times as you like within 12 months. Your return visits must also be booked online.

For the most up to date ticket and booking information see the NMA website. Under 3s are free.

I've heard good things about this aquarium although have yet to go. The interactive exhibits sound fun as well as educational and the doodle pad would be a hit with my daughter too. Thanks for sharing on #citytripping

We had such fun here when we visited, almost exactly a year ago on a torrentially wet day - the doodle pads were a massive hit with my daughter as well. We weren't the only ones with the idea of hiding from the rain but it was well worth the queue.

I've (very recently) become a huge fan of aquariums. The Plymouth aquarium looks amazing, especially for keeping the kids entertained. That photo of your daughter and the turtle is just awesome. I love that they seem to really have thought about ways to engage kids but not at the expense of entertaining adults as well. #CityTripping

My oldest would love this aquarium. And it's pretty impressive that it's the largest in the UK. #citytripping
