ECOTREASURES
Rocky-Reef Snorkeling Tour at Manly & Shelly Beach
4.7 (224) · from $87
The Ecotreasures Manly snorkel tour is a guided swim in Cabbage Tree Bay Aquatic Reserve, starting and ending on the sand at Shelly Beach in Manly. It is not a boat trip, so on a site about boat tours in Sydney it sits as the shore-based option for people who want to be in the water rather than on it.
The detail that changes the decision is the swim test. The operator asks for 150 metres unassisted plus floating and treading water, and says there is no refund if you turn up and cannot do it. Everything else on this page is easier to plan around than that one line.

What is the Ecotreasures Manly snorkel tour and what do you actually do?
It is a 2.5-hour, English-language, small-group session where a local guide walks you along the headland, briefs you on safety, then leads you into the shallows of Shelly Beach for roughly an hour of snorkelling.
- Meet on the sand at Shelly Beach, look for the Ecotreasures flag, and arrive before the start time.
- Walk about 800 metres around the headland for roughly 30 minutes, with talk on the local area, its wildlife and Manly's coastal history.
- Brief and kit up with a safety talk, snorkelling tips and a wetsuit, mask and fins.
- Snorkel across seagrass meadows and rocky reef for about an hour.
- Finish back at Shelly Beach, where the tour ends.
The operator is selling interpretation as much as swimming. The guide is there to name what you are looking at, which is the main reason people who have snorkelled before still book it.
What can you see in Cabbage Tree Bay Aquatic Reserve?
The listing says guides help you identify more than 200 species of fish, invertebrates and algae, and names the blue groper as the headline sighting. Reviewers add a different list from what they actually saw.
- Stingrays are mentioned by several reviewers, with one also logging an eel.
- Port Jackson sharks appear in one review, three at once, described by the reviewer as harmless.
- Blue groper is the species the operator says it searches for in the reef.
- Dense fish schools are the common thread: reviewers repeatedly say they did not expect the variety so close to the beach.
Sightings are not guaranteed, and the listing makes no promise on any species. The operator's own site describes its Shelly Beach tours as running inside Cabbage Tree Bay Aquatic Reserve (Ecotreasures), so the setting is what you are paying for, not a particular animal.
NSW Department of Primary Industries says the reserve covers about 20 hectares of bay, rocky shore and beach from the south end of Manly Beach to the north end of Shelly Beach Headland, and became a no-take reserve in 2002.
It adds that the reserve is one of the most popular snorkelling spots in the Sydney region, and asks visitors to enjoy it without catching, collecting, touching or chasing anything (NSW DPI).
Above the waterline, NSW National Parks notes that the Manly area has the state's only known mainland colony of endangered little penguins, a reason to keep your eyes on the shoreline at dawn and dusk (NSW National Parks).
Where does the Ecotreasures Manly snorkel tour start?
The tour starts and ends at Shelly Beach in Manly, on the sand in front of the Boat House cafe, next to the palm trees, with an Ecotreasures flag marking the group.
The listing's structured data says pick-up and drop-off are not covered, so plan to get there yourself.
One reviewer wrote that they took the ferry to Manly, looked round town and the beach, then walked to Shelly Beach before the tour. That fits the site: Manly is a ferry ride from the city and Shelly Beach is at the far end of the beach front.
- Ferry to Manly - tap on and off with a contactless card, as Transport for NSW explains on its Opal fares and payment pages; fares change, so check them for your date.
- Manly Wharf to the beach - Shelly Beach on Google Maps and a walking route from Manly Wharf. I have not timed it, so leave a generous gap before the start time.
- Meeting spot - Boat House Shelly Beach on Google Maps.
- Town side - Manly Wharf on Google Maps and Manly Beach on Google Maps.
- Reserve - Cabbage Tree Bay on Google Maps.
How does the 2.5 hours break down?
About 45 minutes goes on the walk, talk and safety briefing, and the remaining 75 minutes is in the water, though the inclusions count one full hour of snorkelling.
| Part | Length | What happens |
|---|---|---|
| Walk and briefing | 45 min | Headland walk, wildlife talk, safety briefing |
| Snorkel | 75 min (1 h in the water per inclusions) | Reef and seagrass swim with the guide |
| Finish | - | Back at Shelly Beach |
The AI review summary on GetYourGuide records one repeat comment: some travellers would swap part of the walk for more time in the water. If that is you, the Clovelly snorkel tour below is the shorter, water-first alternative.
Can you join if you are a beginner, and what is the swim test?
Beginners can join, but only if they can swim 150 metres without help and also float and tread water, according to the operator's pre-trip notes in the listing.
- Swim test: 150 m unassisted, float, tread water.
- Refunds: the listing says there is none if you arrive and cannot do it.
- Lessons: short introductory instruction is available for beginners.
- Experience level: the listing says both beginners and experienced snorkellers suit the tour.
Reviews back up the beginner angle: first-time snorkellers say the guide settled their nerves before they got in. The reviews also all come from a positive-only sample (ten 5-star reviews under the "Recommended" sort), so I treat that as reassurance about guide quality, not proof that nobody struggles.

What is included and what do you pay extra for?
Gear and a guide are in the price; food, drinks and transport are not.
| Item | Status |
|---|---|
| Guide with interpretation | Included |
| Mask, snorkel, fins and wetsuit | Included |
| Safety briefing | Included |
| 800 m headland walk | Included |
| Food and drinks | Not included |
| Pick-up and drop-off | Not included |
The raw listing shows "Food and drinks" and "Pick up and drop off" in the included list, but the structured data on the same page puts them under not included, and the meeting point is a fixed spot on the beach.
I trust the structured data here and treat both as extras. The listing's bring-list is a sun hat, towel, sunscreen, comfortable shoes, a reusable bottle and swimwear.
What are conditions like by month?
Air is mildest from December to March and coolest in June and July, while the 20.0°C sea reading on 18 October tells you the wetsuit is doing real work most of the year.
| Month | Avg high 2025 | Avg high 2015-24 | Rain days (1 mm+) | Advice |
|---|---|---|---|---|
| Jan | 25.3°C | 26.7°C | 12.7 | Warm air; the wetsuit does the work in the water |
| Feb | 26.1°C | 26.0°C | 13.2 | Warm air; the wetsuit does the work in the water |
| Mar | 25.7°C | 24.8°C | 15.0 | Warm air; the wetsuit does the work in the water |
| Apr | 23.3°C | 22.5°C | 10.1 | Mild; expect a cool first minute in the water |
| May | 19.4°C | 19.6°C | 7.5 | Cold air; pack a warm layer for the walk back |
| Jun | 16.3°C | 16.9°C | 9.8 | Cold air; pack a warm layer for the walk back |
| Jul | 16.2°C | 17.0°C | 7.3 | Cold air; pack a warm layer for the walk back |
| Aug | 16.9°C | 18.2°C | 6.2 | Cold air; pack a warm layer for the walk back |
| Sep | 22.1°C | 20.6°C | 7.6 | Mild; expect a cool first minute in the water |
| Oct | 25.8°C | 22.5°C | 11.2 | Mild; expect a cool first minute in the water |
| Nov | 25.7°C | 23.7°C | 11.2 | Mild; expect a cool first minute in the water |
| Dec | 26.6°C | 25.8°C | 10.3 | Warm air; the wetsuit does the work in the water |
Temperatures come from the Open-Meteo archive for the harbour, not the beach, so the coast can run a degree or two different. Rain days are days with at least 1 mm.
One reviewer in September said the air was cold enough that they almost skipped it, then praised the thick wetsuit. Wave height off the Heads was forecast at about 1.0 m for 18-20 October (Open-Meteo Marine): the bay is sheltered, the sea outside it is not.
20.0°C was the modelled sea surface temperature off Sydney's Heads on 18 October 2026, at a forecast wave height of about 1 metre.
Is the Ecotreasures Manly snorkel tour worth it versus other Sydney snorkelling?
At $34.8 per tour hour it is cheaper than the $42.0 city median and cheaper per hour than the Clovelly session, but you are paying for a walk and talk as well as the swim.
| Tour | Price | Length | Rating | Best for |
|---|---|---|---|---|
| Ecotreasures Manly (this page) | $87 | 2.5 h | 4.7 (224) | Guide-led reserve walk and swim |
| Sydney Snorkeling, Clovelly | $64 | 1.5 h | 4.7 (185) | Cheaper, more water per dollar |
| Manly guided snorkel for non-swimmers | $114 | 1 h | 4.8 (10) | People who fail a swim test |
| Transparent kayak, Manly Cove | $66 | 2.5 h | 4.8 (220) | Seeing the water without swimming |
For a first snorkel where you want the guide to name the fish, I'd book this one. For the lowest price and the most water time, I'd go to Clovelly. Browse the full snorkelling tour Sydney list for the rest.
Is a guided Shelly Beach snorkel worth it over going in alone?
For most visitors, yes, because the guide handles the walk-in, the kit and the swim route, and Shelly Beach lies inside a protected reserve where the briefing matters.
- Guide - sub-score 5.0 on GetYourGuide, the highest of the three rated categories.
- Transport - sub-score 4.8, mostly the meeting point and organisation.
- Value for money - 4.7, the lowest of the three; one reviewer called it a little pricey but good fun.
Going alone costs a mask and fins and saves roughly the ticket price, but you lose the wetsuit, the interpretation and a spotter in the water. I would only skip the tour if you already snorkel confidently and own your kit.

What do passengers say?
Reviewers mostly talk about the guides, the safety and the fish, and the one critique is the balance of walking and swimming.
- Guides come up in almost every review, usually by first name, with praise for patience with nervous first-timers.
- Marine life is the second theme: rays, an eel and a shark are all named.
- Gear gets a mention: reviewers mention thick wetsuits and good-quality masks and fins, and say belongings were kept secure.
- The recurring complaint is time: some wanted more water and less walking.
The sample I can see is ten 5-star reviews sorted by "Recommended", so the complaint count is almost certainly understated. The 4.7 average over 224 reviews is the better signal.
Who should skip the Ecotreasures Manly snorkel tour?
Skip it if you cannot swim 150 metres unaided, dislike cold water, or want a boat trip, because this tour never leaves the shore.
- Weak swimmers - see the non-swimmers' tour above.
- Travellers wanting a boat - head back to all boat tours in Sydney.
- People short on time in the water - the 75 minutes include a briefing; some reviewers wanted more swim time.
- Anyone needing transport - pick-up is not included, per the structured data.
