The Oceanarium sits right on the seafront at Pier Approach, a few steps from the pier and the beach. It is the kind of place that earns its keep on a grey afternoon, but plenty of families make a beeline for it whatever the weather.
The essentials
- The aquarium is on the seafront, just west of the pier entrance.
- Exhibits are themed around different aquatic environments from around the world.
- It is fully indoors, which makes it a strong rainy-day and family choice.
- Allow one to two hours, and check tickets and feeding times before you go.
What you will see inside
The Oceanarium is arranged as a journey through different watery worlds rather than a single hall of tanks. You move from cooler local waters through to warm tropical zones, taking in coral displays, rays gliding over sandy floors and the slow, hypnotic drift of larger fish. An underwater walk-through gives you the classic aquarium moment of standing with water and sharks on either side and overhead. The route is easy to follow with children, and the darker, glowing tanks hold the attention of even the youngest visitors.
Feeding talks and the animals
Beyond the fish, the site is known for a few crowd-pleasers: penguins with their own outdoor area, otters, and turtles among the larger residents. The keeper talks and feeding sessions are worth planning around, as they turn a walk past a tank into something the children actually remember. Times are posted through the day and change with the season, so ask at the entrance or check ahead and build your visit loosely around one or two of them.

A reliable option when it rains
Bournemouth has a long list of things to do outdoors, and a much shorter one for when the sky opens. The Oceanarium is near the top of that shorter list. It is warm, dry and self-contained, and the loop takes long enough to see out a passing shower without feeling stretched. If the forecast has turned on you, our roundup of things to do when it rains puts the aquarium alongside the other indoor options so you can plan a full day under cover.
Making a day of it
Part of the appeal is where it sits. Step out of the Oceanarium and you are on the promenade, with Bournemouth Pier and its indoor activity centre a minute’s walk away and the beach immediately in front of you. That clustering means you can combine a morning at the aquarium with a walk on the pier and lunch on the front without moving the car. For families in particular this is a natural pairing, and our Bournemouth with kids guide maps out how to link these seafront stops into an easy day.
Practical notes
The Oceanarium is pushchair friendly and mostly on the level inside, with the usual cafe and shop at the end of the route. It gets busy in the holidays and on wet days, when everyone else has had the same idea, so an earlier start or a pre-booked ticket helps. Prices and opening times shift through the year, so confirm the current details with the attraction before setting off rather than assuming.
Where to go next
The aquarium is one anchor of a good family day on the front. To see what else pairs with it nearby, browse the wider list of things to do in the guide, or read on for more ideas aimed squarely at younger visitors.
