An incredible amount of sealife packed into the aquarium at the end of the pier. Volunteers are always so helpful and kind to answer all my kids questions.
Love the touch tank!

🐬The Roundhouse Aquarium, perched at the end of the Manhattan Beach Pier, is a hidden gem that offers an intimate and engaging marine experience. Housed within a charming building reminiscent of coastal architecture, this small aquarium makes a big impact with its immersive displays and welcoming atmosphere.

Upon approaching, visitors are greeted by “Manny,” a larger-than-life white shark sculpture that piques curiosity and excitement. Once inside, the aquarium offers a fascinating peek into the underwater world with exhibits like the “Immersion Gallery.” This unique exhibit captivates guests with jellyfish gracefully floating in vibrant, illuminated tanks, creating an almost ethereal ambiance.

Despite its modest size, the Roundhouse Aquarium impresses with well-curated educational content, interactive displays, and an inviting environment perfect for families, tourists, and locals alike. The staff are friendly and knowledgeable, eager to share insights and answer questions, making the visit both informative and enjoyable.

Whether you’re taking a leisurely stroll along the pier or exploring the marine life within, the Roundhouse Aquarium provides a delightful stop. It’s a beautiful blend of education, wonder, and oceanfront charm—a must-visit destination for those exploring the scenic Manhattan Beach area.

Wonderful little gem of a place! Small enough to easily walk through while genuinely enjoying the wildlife displays and interactive experiences! The aquarium is conveniently located at the end of Manhattan Beach Pier. There are educational labels with pictures at each display, and there is a tide pool with guided interactive experiences on site for kids of all ages! The moon jellyfish were so cool to watch! Definitely if you are in the area check it out! It's easy to get to and free to enter, although donations are encouraged and accepted.

Part of the delight visiting the Roundhouse Aquarium is the easy stroll along an extended pier standing in the deep water for many to admire... the ocean, ships and surfers. If lucky, the sunset is absolutely gorgeous! Like other piers, many find the pier filled with fishing folks and entertainers.

The Aquarium is tiny, compact, educational, and "free". Yes, as pricey as everything associated with the coastal cities, this gem is basically free and open to the public with limited hours. Donations are welcome.

It's enjoyable for those with extra free minutes to wander around, both first and a second floor. Kids have the opportunity to touch live sea creatures in a tank! Splendid time to expose youngsters to appreciate sea life and value nature in front of them.

Plus side of walking the pier... at the start of the it, there are public bathrooms, but not at the Aquarium.

Would we visit again? Definitely! The pier walk is worth it!

It's a small aquarium/teaching center located in Manhattan Beach pier. You can visit it for free, but I recommend making a donation, it have 2 levels and different species that you can see along the tour.

The Roundhouse Aquarium is a really cool free aquarium. It is fun to check out if you're at the Manhattan Beach Pier and is relatively quick to enjoy!
