Best Things to Do in Catalina Island, CA With Kids
Catalina Island's best family days are the Catalina Express ferry from the mainland (the way over), a glass-bottom or semi-submersible boat tour of the kelp forest, swimming and snorkeling at Descanso Beach Club, the Catalina Zip Line Eco Tour over Descanso Canyon for kids 10+, and a golf cart rental to tour Avalon — since cars are heavily restricted on the island.

The standard way to reach Catalina — a fast catamaran departing from Long Beach or San Pedro, with several daily departures. Getting there is genuinely part of the family trip.
Watch out: Book round-trip tickets in advance for summer weekends — sailings fill. Seas can get choppy on the crossing; bring motion-sickness remedies for kids prone to it.

A guided boat that lets you view the kelp forest and fish through the hull without anyone getting wet — ideal for kids too young to snorkel, and a good preview for kids who'll snorkel later in the trip.
Watch out: Choppy days can force a cancellation or reschedule. Visibility underwater is noticeably better on calm, sunny days than overcast ones.

The calm cove right in Avalon, with snorkel gear rental on-site and clear, easy-entry water — the go-to spot for a first-time family snorkel without booking a boat.
Watch out: There is an entry fee to the beach club. The bottom is rocky in spots, so water shoes help. Gets crowded midday in peak season.

Five zip lines strung across Descanso Canyon, with a guided eco talk on the island fox and native plant life woven in — real adrenaline for tweens and teens after a couple of slower beach days.
Watch out: Minimum age is typically 10 and weight limits apply — check specifics before booking, as this rules out most younger kids entirely. Book a morning slot to beat the afternoon heat on the shuttle up.

Cars are heavily restricted on Catalina, so golf carts are the real way to get around — renting one and driving up into the hills for a harbor view is a genuinely different family activity than a normal town tour.
Watch out: Most rental outfits require the driver to be 25 or older with a valid license. Carts sell out on busy weekends — reserve ahead. Some hillside roads are narrow and steep.
Frequently asked
Do you need a car on Catalina?
No — cars are restricted island-wide. Golf carts and walking cover Avalon, and Discovery Tours or local taxis handle everything farther out.
Best for young kids (under 6)?
The glass-bottom boat tour and Descanso Beach Club. Skip the zip line — it has a hard age and weight minimum around 10.
Day trip or overnight?
A day trip from LA works (early ferry over, evening ferry back), but an overnight lets you add the zip line and a relaxed beach morning without rushing.
Budget for a day trip, family of 4?
Ferry, one boat tour, beach rental gear, and lunch typically runs $600–$900 for the day.
