Discover Catalina Island's marine life on a 45-minute glass-bottom boat tour. Enjoy vibrant fish, kelp forests, and marine creatures with flexible departures.
If you’re visiting Catalina Island and want a peek into its underwater world without getting your feet wet, the Sea View Glass Bottom Boat Excursion might catch your eye. This short and sweet experience offers a window into California’s marine ecosystem, floating above colorful fish and kelp forests while enjoying the fresh sea breeze. It’s popular among families, couples, and curious travelers alike.
What we particularly like about this tour is its convenient schedule — several departures throughout the day make fitting it into your Catalina itinerary quite easy — and the interactive element of feeding fish right from your seat. However, a key consideration is that the trip is fairly brief — at just 45 minutes — and some reviewers mention that the underwater views can sometimes be obscured or less dramatic than expected.
This experience suits those looking for a relaxed, family-friendly activity that offers a taste of Catalina’s marine life without heavy investment of time or money. If you love ocean views and small-group excursions, this tour can be a charming add-on to your Catalina adventures.

This tour departs from the Green Pleasure Pier in Avalon, offering a 45-minute narrated journey into Lover’s Cove, a protected marine reserve. The experience combines spectacular above-water coastline views with a clear view beneath the surface through the boat’s glass panels.
Travelers will glide across the water, observing the rocky shoreline, rugged cliffs, and perhaps spotting the occasional sea lion or seabird. The real highlight, however, is the underwater scene — a lively kelp forest populated by garibaldi, kelp bass, leopard sharks, bat rays, and moray eels. If luck is on your side, you might even see a sea turtle or two.
The boat is designed with viewing windows on the bottom, allowing you to see marine life without diving or snorkeling. Some reviews mention that the clarity of the view can be compromised by air bubbles or blurred glass, which is frustrating but not uncommon in glass-bottom boats. The boat is small, with a maximum group size of 48, creating an intimate and relaxed atmosphere.
Looking for more options in Catalina Island? Here are some other experiences worth considering.

Stop 1: Lover’s Cove Marine Reserve – This is the heart of the tour, where almost everything happens. Known for its crystal-clear waters and vibrant kelp forests, Lover’s Cove is a prime spot for observing marine animals at close range.
As the boat gently moves through the reserve, a narrator points out the various sights, explaining what’s beneath the surface. You’ll get a 360-degree view of the coastline from above and below, which makes for some great photo opportunities. The feeding fish from designated feeders at each seat is a fun, interactive part of the tour, giving everyone a chance to see the fish swarm and get a little closer to the underwater creatures.
What you might see: Garibaldi, the bright orange California state fish, are often seen in large groups. Kelp bass and leopard sharks are common, and some lucky passengers report seeing bat rays gliding through the water. Moray eels hide among the rocks, and there’s always the chance of spotting a sea turtle if the timing is right.
Duration and pacing: The tour lasts about 45 minutes, which many find just enough time to get a good glimpse of marine life without fatigue. One review describes it as “just long enough to not get bored,” highlighting the importance of a concise, engaging experience.

The reviews paint a nuanced picture. Several travelers praise the “fun ride,” noting that the fish sightings are plentiful, and the views are colorful and lively. One reviewer said, “Tons of fish swarm the windows,” emphasizing how interactive and visually stimulating the experience can be. They also appreciated the timeliness and friendliness of the crew.
However, some passengers found the experience less impactful. A critical review mentions that “more than half of the viewing window was blurred by an air bubble,” making it hard to identify fish and marine creatures clearly. This points to the fact that, like many glass-bottom tours, the clarity can vary due to weather, maintenance, or technical factors.
Another reviewer felt the trip was too short and not particularly educational — mostly just a quick fish-feeding session. The lack of detailed information about the marine life was noted, but this may not bother everyone if your main goal is simple fun and sightseeing.
At $49 per person, this tour offers a reasonable price point for a quick, engaging marine experience. It’s a good value for those who want a snapshot of Catalina’s underwater environment without diverging into lengthy or costly excursions.
The tour is operated by Catalina Adventure Tours and can be booked with ease, with most travelers finding the meeting point on the Green Pleasure Pier straightforward to locate. The boat’s maximum capacity of 48 travelers helps keep the atmosphere intimate, avoiding the crowded feel of larger tours.
Flexibility: The multiple departure times make it easy to coordinate with other activities — whether you’re arriving by cruise ship or staying in Avalon. The tour is suitable for most travelers, including children (who must be accompanied by an adult), service animals, and those with mobility considerations.

Since this is an outdoor activity, good weather is essential for the best experience. The tour provider offers free cancellation up to 24 hours in advance, allowing some peace of mind if weather turns unfavorable. If canceled due to poor conditions, you’ll be offered a different date or a full refund.

This glass-bottom boat ride is perfect if you’re craving a relaxed, family-friendly activity that offers a taste of Catalina’s marine beauty. It’s ideal for first-time visitors wanting a quick, visual introduction to local marine life, or for those with limited time who still want a memorable experience. It’s also a nice choice if you’re traveling with kids who might find snorkeling or diving too intimidating or physically demanding.
If you’re seeking an immersive, educational marine adventure, this might fall short — but if your priority is fun, scenery, and a bit of marine wildlife, it’s a charming option.

The Sea View Glass Bottom Boat Excursion delivers a simple, accessible window into Catalina’s underwater world, with bright fish, kelp forests, and marine creatures just beneath the surface. It’s a great value for families, casual travelers, or anyone wanting a quick, scenic boat ride with a marine twist. The interactive fish-feeding and stunning coastline views make it engaging, especially for those new to snorkeling or marine exploration.
However, if you’re someone craving a longer, more detailed marine education or hoping to see rare or elusive creatures, you might find this tour a bit limited. Also, keep in mind that the view clarity can vary, and 45 minutes means you’ll want to stay attentive to maximize your viewing time.
In all, this experience offers a light, enjoyable glimpse of Catalina’s marine environment, perfect for a laid-back day on the water. It’s best suited for families, casual explorers, and anyone eager for a quick splash of ocean magic — without needing a wetsuit or a lot of time.
“We didn't spot anything unusual or super-exciting just lots of fish and a sea lion. Safe and fun. Nice to see what goes on under the water instead …”
