Why Redondo Beach’s Glass Bottom Boat Is the Summer Adventure Everyone Should Try

Tucked inside King Harbor, the Redondo Beach Glass Bottom Boat offers one of the most unexpectedly fun outings in the South Bay. Equal parts sightseeing cruise and underwater adventure, this family-friendly excursion lets visitors get face-to-face with local marine life without ever getting wet.

A Different Perspective on Redondo Beach

From the outside, the bright yellow boat looks like another harbor tour. But once you step aboard, it quickly becomes clear that this isn’t your average cruise.

The experience begins on the top deck, where the captain navigates around King Harbor in search of one of the marina’s biggest celebrities: California sea lions. They lounge on floating docks, bark at passing boats, and often provide plenty of entertainment before the real adventure begins.

Then comes the part everyone waits for.

Passengers head downstairs into the underwater viewing chamber, where large windows reveal an entirely different world. Schools of fish glide past while bright orange garibaldi, the California state marine fish, flash through the water alongside calico bass, perch, opaleye, and smelt. The windows stretch roughly seven feet long, giving guests an up-close look at life beneath the harbor.

A Hidden South Bay Gem for Families

In a region filled with big-ticket attractions, the Glass Bottom Boat feels refreshingly simple. Kids are fascinated by spotting fish inches away from the windows, while adults appreciate the relaxing pace and scenic harbor views.

Tours last about 45 minutes, making them easy to fit between brunch, beach time, or an afternoon exploring the Redondo Beach Pier. And because the boat stays inside King Harbor’s breakwall, the ride remains calm and comfortable even for first-time boaters.

It’s an activity that appeals to grandparents, toddlers, couples, and curious visitors alike.

More Than Just a Boat Ride

Captain Jake Mark, a lifelong South Bay local and U.S. Coast Guard licensed captain, has turned the experience into something that feels personal rather than touristy. The boat itself has been delighting visitors for more than two decades and undergoes annual Coast Guard inspections.

Perhaps the most impressive detail? The company offers a wildlife guarantee. While mermaids aren’t promised, sightings of sea lions, pelicans, and several species of fish are. If guests somehow don’t see any wildlife, they’ll receive a refund.

Make It a Full Day at the Harbor

One of the best things about the Glass Bottom Boat is its location. The boat departs from the International Boardwalk near King Harbor, making it easy to pair with lunch, drinks, or a walk around the waterfront.

Spend the morning at the beach, hop aboard the afternoon cruise, and finish with fresh seafood while watching sailboats drift through the marina. It’s the kind of easygoing summer itinerary that reminds you why locals love the South Bay.
