What You Can Expect

Rottnest Island Snorkeling Cruise with Optional Guided Walking Tour and Lunch

Snorkelling on Rottnest Island

Your Rottnest Island day trip starts in either Perth or Fremantle, depending on option selected when booking. From Perth, cruise down the Swan River on the ferry, taking in views of the upscale homes and yacht clubs that line the shore. When you get to Fremantle, where the river meets the Indian Ocean, pick up more passengers for the trip across the sea to Rotto, as the island is known to locals.

When you arrive, explore independently before your snorkeling tour later. You may join a free 20-minute guided walking tour around Thompson Bay, the main township on the island, or check out the sights on your own. If you select the lunch upgrade option when booking, make your way to the Rottnest Lodge at the specified time to enjoy a selection of hot dishes, salads, deli items, dessert and beverages from the buffet.

Then meet up for your 1.5-hour snorkeling tour, which starts at 1:45pm. Grab your provided equipment and take off by boat to one of Rottnest’s many turquoise bays; depending on the weather and sea conditions, you may visit Salmon Bay, Green Island or Catherine Bay. Spend about 60 minutes snorkeling, admiring the underwater world of coral and fish, such as harlequin fish, West Australian pearl perch, leatherjacket, baldchin groper, butterfly fish and moon wrasse. You may also spot crustaceans like the blue manna or Western rock lobster.

When your snorkeling cruise ends, return to the main jetty for more free time to hang out on the beach or visit local shops before catching the ferry back to Fremantle or Perth.

A very good day from start to finish. You get there by comfortable boat and there is a commentary on board which is useful. Once on the island I opted for the high-speed tour around the island in the commando boat. Stopped to see loads of wildlife. This was not part of the Viator schedule (although Viator do a tour without the snorkelling that includes this high speed trip) but there was time to do this instead of the walk around a bit of the island. Lunch was good. Then straight back to the same guys in the same boat. Safety and the like was good: kit provided was all in good condition (short wet suits and rash vests, snorkel and mask).
There were only eight of us in the group - a good number.
The snorkelling lasted about one hour of actual in-the-water time. Well organised.
It is easy to float, face down and snorkel in sea water so don't worry too much about prior snorkelling experience but you do need to have used a snorkel before - local swimming pool? and you can't touch the bottom so you need to be able to swim.
I am a poor swimmer and novice snorkeller and I felt fine on this tour.
Home is by the ferry.
I didn't have a chance to explore the island but there is certainly enough to do there and it the island is well organised so a return trip or even a 1-2day stay would be good.

Beautiful Island, I'd recommend skipping the snorkelling and enjoying more time on the island itself


4 star rating: Recommended February 2016

Great trip to the island and snorkeling site. The only flaws are that I wish we had more time on the island and the buffet lunch had very limited options not worth the extra price paid
