Key visa, timing, safety, customs, currency, transport and must-know tips for a smooth trip to Santa Catalina Island, California.

Q: What should I know before visiting Santa Catalina?

Direct answer

Santa Catalina Island (often just "Catalina") is a short ferry or flight from Southern California with outdoor activities, a small-town vibe in Avalon, and limited services — plan ahead for transport, weather, and reservations.

Visa / entry requirements

  • For U.S. citizens: no passport required if traveling from the U.S. mainland. Bring a valid photo ID (driver's license) for ferries. If arriving by private boat, follow U.S. CBP procedures.
  • For international travelers: a passport is required to enter the U.S. If you’re already in the U.S., carry your passport or any required immigration documents. No separate island visa.
  • If arriving by private boat or seaplane and then returning to the mainland, be prepared to show ID and any CBP paperwork — check CBP rules in advance.

Best time to visit

  • Peak season: late spring through early fall (May–September) — warmest weather and best water activities but busier and pricier.
  • Shoulder seasons: April and October offer milder crowds, cooler temps, and good deals; some services may be reduced in winter.
  • Winter: quieter, cooler, occasional rain; some attractions and tours run limited schedules.

Safety tips

  • Ocean safety: currents and cold water can be hazards. Swim only in designated areas, heed lifeguard warnings, and use life jackets for kayaking/snorkeling if unsure.
  • Sun protection: strong sun exposure — wear sunscreen, hat, and sunglasses.
  • Hiking: trails can be exposed and dry; carry water, a map, and sturdy shoes; tell someone your route and expected return time.
  • Wildlife: do not feed or approach wildlife (foxes, birds). Seal and sea lion encounters should be observed from a distance.
  • Emergency services: medical facilities are limited on the island — know locations of the Avalon medical clinic and how to reach emergency services.

Local customs and etiquette

  • Small-town courtesy: Avalon is compact; be respectful of residents and businesses. Service can be friendly but slower than big cities.
  • Noise and nightlife: quiet hours may be enforced in some lodging areas — be considerate.
  • Environmental respect: Catalina has unique ecosystems and marine reserves — follow Leave No Trace principles and reef-safe sunscreen where advised.

Currency and payments

  • Currency: U.S. dollar (USD). Credit/debit cards are widely accepted in Avalon; some smaller vendors may prefer cash.
  • ATMs: limited — bring cash for markets, tips, or smaller purchases. Inform your bank of travel to avoid card blocks.

Transportation on the island

  • Getting there:
    • Ferries: regular ferries run from Long Beach, San Pedro, Dana Point, and Newport Beach to Avalon and Two Harbors. Book in advance during peak season.
    • Flights: small-plane flights (swiftair/western commuter services) to the island’s airport (Airport in the Sky) or seaplane services provide faster options.
    • Private boat: moorings and marina slips are available but limited; reserve ahead.
  • Getting around:
    • Avalon is walkable and bike-friendly; golf carts, taxis, and shuttles are common for getting around town.
    • Two Harbors and interior trails: a vehicle (rental, jeep, or guided tour) is useful for exploring beyond Avalon.
    • Car rentals: there are no conventional car rentals in Avalon; some off-road vehicles and ATVs are available through authorized operators.

Must-know tips and local insights

  • Book lodging and ferries early for summer weekends and holidays.
  • Popular activities: snorkeling/diving in Lover’s Cove and Casino Point, glass-bottom boat tours, hiking (Trans-Catalina Trail segments), zip-lining, and wildlife/whale-watching tours.
  • Dining: Avalon has a range of restaurants; for special diets or popular spots, reserve ahead. Grocery and specialty items can be limited/expensive.
  • Water and supplies: tap water is potable, but bottled water and supplies are pricier — bring essentials if you have dietary needs.
  • Trash and recycling: pack out what you can; follow local disposal rules.
  • Two Harbors vs Avalon: Two Harbors is quieter and more rustic — choose based on whether you want nightlife and services (Avalon) or solitude and camping (Two Harbors).
  • Cell service and connectivity: coverage can be spotty in parts of the island — download maps and confirmations beforehand.
  • Respect private property: many inland areas are private or part of Catalina Island Conservancy land with access rules; check permits for backcountry camping.

Quick checklist before you go

  • Ferry or flight reservations
  • Lodging confirmed and contact info
  • ID/passport and any CBP paperwork if relevant
  • Cash, cards, and small first-aid kit
  • Sun protection, reusable water bottle, and proper footwear
  • Book popular tours/activities in advance

Enjoy Catalina: pack for outdoor fun, plan logistics ahead, and savor the island’s natural beauty and relaxed pace.
