Truly wonderful experience. Loved the glass bottom boat tour with knowledgeable interpretation and plenty of free time to snorkel off the beach. Crew were outstanding. Great diversity of fish and inner reef coral , and turtles, and baby reef sharks. Snacks provided at end was a great way to finish. Early start meant not too hot

Highly recommend snorkelling the Low Isles! It was a really easy experience and honestly just a lot of fun. The guides were great and I even got to see a turtle!

Overview

Snorkel in the coral gardens, walk around the tiny islands, or take a glass-bottom boat tour so you can stay dry while admiring the underwater world. Choose whether to snorkel with or without a guide, depending on your confidence level.
  • Snacks, coffee, and tea are provided to keep you fueled throughout
  • Return to Port Douglas in time for lunch or dinner on a half-day tour

    Unreal afternoon! The staff were fantastic and absolutely went out of their way to look after my partner who was struggling with seasickness. Saw turtles, great reef life, giant clams, big and colourful fish - so good!

    Great tour for a quick look at the reef. I think this tour is good for people concerned with seasickness (me), have small kids, or are short on time. May not have been the “best” reef but saw lots of fish and there was a nice island to relax if you did not want to snorkel the entire time

    Awesome experience to be repeated!

    Deadra_P, Jul 2025
    Had a fabulous time - small friendly group were assisted by friendly and helpful crew. Had an absolutely wonderful time snorkeling and viewing the range of sea life - fish, coral, turtles etc. Half day was a good test to see how I would go with snorkeling in the reef - so now looking forward to the next trip to Port Douglas to participate in the day trip to Outer Reef.

    Relaxing morning activity

    Great half day snorkelling trip. Staff very friendly and attentive. We got to see many different varieties of beautiful coral fish and several turtles.

    Indian family, non swimmers with a kid. Super awesome calypso team

    Suresh_S, Apr 2025
    Amazing experience. We were non swimmers with an 8 year old child, Indian family. The staff was very helpful all throughout. The noodles and lafe jackets were easy to use and kept us afloat. We were very scared to snorkel (like panic atrack level scared!!!!) and Kate who was a marine biologist, made us feel extremely comfortable and helped us experience snorkeling. We were lucky to see, giant turtles up close, the reef and many beautiful 🐠🐋🐟. Thanks Calypso team. Tip: skip the breakfast of keep it super light.

    Fun family tour

    Loved our tour guides and had a wonderful time. Nice snack and drinks at the end!! Snorkeling was easy!

    Terrible tour group

    AnneSullivan, Jan 2025
    We were in the terminal at 1 pm for a 1:15 tour. Went to change into our bathing suits and they left without us. Front desk operations was terrible. We use Viator All The time. No refund. No apology. Do not book this tour

    Awesome experience

    Helena_M, Jan 2025
    It was a wonderful excursion. Rene, Mikey and the other crew (sorry don’t remember his name) were excellent. Rene was especially helpful for my husband who has some mobility issues. She went above and beyond what she needed to, to make this experience the best it could be

    Excellent day

    Sean_C, Jan 2025

    First class trip

    Friendly, informative kick ass women who provided an amazing day. The location was perfect and snorkeling was on point. We would recommend this tour for any tourist including locals who can enjoy their amazing backyard of sea, fish and good people.

    Catherine_M, Nov 2024
    We were both quite apprehensive (i also can't swim) but once we got going we absolutely loved it and want to go out for a full day now! I used a life jacket so that made me feel safe to. Best experience, we highly recommend it!!

    Great experience

    Meirion_J, Oct 2024

    Seeing turtles and reef sharks in their natural habitat as we snorkelled on the reef. Excellent skipper Jorge and team of Nicole and Jared made this trip an absolutely great experience.

    Calypso snorkelling in port Douglas

    Karen_O, Sep 2024
    Amazing from the minute we booked in we were made to feel welcome and relaxed. It was my 1st time snorkelling so I was a bit nervous but with my husbands and the help of the crew we had a great time ! The fact that I am disabled they we all very patient with me and I didn’t feel a pain. We saw many different types of fish and we saw 4 turtles and a baby turtle. I would definitely recommend this company Calypso it is amazing! Thank you from Karen and Pete from the uk !!

    Good half day tour for the family

    Paul_W, Sep 2024
    Small group of people with opinions to snorkel, tour the island or experience the glass boat ride. Friendly staff who gave plenty of advice & freedom

    Magically enchanting

    Jacqueline_R, Sep 2024
    Friendly staff , helpful as we Are not confident snorklers but felt very safe and really enjoyed the experience. We enjoyed the lower isles that much with calypso that we went back and booked the outer reef tour with them as well, it was all very magical, what a wonderful experience we had . Thank you for an amazing time

    Tour guides were very knowledgeable and friendly, even though it rained it was an amazing experience Got to snorkel with turtles best birthday ever

    Low Isles interesting

    Jennifer_T, Aug 2024
    The island tour was very interesting. The Glass Bottom Boat had a lot of interesting information, however the reef was underwhelming.

    So worth it! Kids and parents all enjoyed!

    Colleen_C, Jul 2024
    Such a great crew and fun afternoon ~ a huge thank you guys! Very informative, saw lots of lovely coral and sea life. The snorkelling was stunning and the glass bottom boat was fantastic. Kids loved the fruit and muffins, and the cup of tea was much needed- thirsty work all this swimming and island exploring! We had kids ranging from 8 to 14 and everyone loved it.

    Book this tour!

    Pete_G, Jun 2024
    Roman, Taylor and Darcy were our awesome tour guides out to the Low Isles and on the glass bottom boat tour. They were super knowledgeable about the reef, Lowe Island and the history and my family and I learnt a lot. They made the experience a lot of fun and we highly recommend this tour. Half day was great for us but I think they do full day tours as well.

    Super relaxed snorkel-Great for all levels.

    Jade_S, Jun 2024
    We had a wonderful experience snorkeling and wandering the beach at low isle. We loved the unstructured snorkel- at -your- own- pace vibe. We saw plenty of turtles and two types of sharks along with a lot of reef fish. We skipped the glass bottom boat tour. The reef was a bit bleached from the heat and all the rain but it was still a lovely time.
