The Cape RADD sea forest snorkel is a 2-hour guided snorkel in the kelp forest of False Bay, led by a marine biologist for a group of up to 8, for $73 per person and a 4.9/5 rating from 140+ GetYourGuide reviews.

The detail that changes the decision is that there is no boat.

You walk in from the shore, so this page belongs in a boat tours directory only as an on-the-water alternative: if you are here for a boat, my Waterfront sparkling wine cruise page covers a sail, and the Cape Town snorkeling guide and the full list of Cape Town boat tours show every option.

If you want cold, clear water and a shark egg case, read on, and you can start again from the home page at any point.

What is the Cape RADD sea forest snorkel and what do you see?

It is a guided snorkel through a kelp forest with a marine biologist, where the animals are small and the main attraction is the ecosystem itself.

• Kelp forest: reviewers describe giant kelp swaying overhead and a sea floor crowded with life.
• Sea stars and urchins: mentioned in several reviews; the listing says the guide explains why urchins carry bits of kelp on their backs.
• Octopus and shysharks: the listing says you learn how octopi hunt and where shysharks hide; reviewers saw small sharks and a shark egg case.
• Seals: wild seals appear in a reviewer's account.
• Citizen science: you help the biologists collect photo identifications of a harmless endemic shark species and get access to the FinSpotter app for your sightings, per the listing.

The briefing before the water gets the most praise: reviewers say they saw more because the guide told them where to look. The animals are not promised, and the visible reviews are all five-star, so treat the shark sightings as typical but not guaranteed.

Is a boat used on the Cape RADD sea forest snorkel?

No: the snorkel starts from the shore, not from a boat, and nothing in the listing mentions a vessel.

The listing sends you to the dive centre on the False Bay shore, and a reviewer mentions a beach.

Cape RADD's own page for its similar Snorkel for Science trip says shore entry (caperadd.com), and I treat this trip the same way; the operator page does not list this product by name, so confirm the entry point on your voucher.

If a boat matters to you, the Mola Mola snorkel from Langebaan uses a RIB, and the Cape Town boat tour list shows the sailing options.

Where does the Cape RADD snorkel meet?

You meet at the Cape RADD dive centre by the water, and the listing pin and the operator's address are close but not identical.

The listing gives a pin just north of Simon's Town. The operator's homepage lists its dive centre at 117 St George's Street in Simon's Town, called the Ocean Hub (caperadd.com). When two sources conflict, use the address on your booking confirmation. Cape RADD, Simon's Town on Google Maps

1. Arrive at the dive centre for check-in and the biologist's briefing.
2. Fit the wetsuit, hood if offered, mask, snorkel and fins.
3. Walk to the water and enter from the shore with your group of up to 8.
4. Snorkel the kelp forest with the guide, then return to the dive centre.

Simon's Town is a separate town on the False Bay coast; the listing does not say how to get there or give a meeting time, so check the voucher. Maps links: Simon's Town, Boulders Beach and Simon Town waterfront.

How long is the snorkel and what is the water like?

The snorkel session lasts 2 hours, including the briefing, and the water is cold: 16.1 C in False Bay this week.

For the Cape RADD sea forest snorkel, two hours is the whole activity, not 2 hours in the water, and I could not confirm the split. Reviewers say wetsuits with hoods and boots were enough in July and thick suits worked for a winter-time guest.

The listing says the activity takes place rain or shine, so the sea state is the real limit; the operator may move the site if conditions are poor, though the listing does not say so.

What is on board and what is included?

The price covers the guide, the briefing, snorkelling equipment including a wetsuit, and photos; towels and swimwear are yours to bring.

Part of the point is to feed data to marine research, and the operator's related page asks for competent swimmers and a signed indemnity for under-18s (caperadd.com).

That rule is for a different Cape RADD product, which also sets a 12-year cut-off, so I use the 10-year rule from this listing and suggest asking the operator.

How does it compare with the other Cape Town snorkel trips?

It is the best rated of the three and sits next to the African Ocean Adventures Simon's Town snorkel on price, while the Mola Mola trip is a different, boat-based product.

The African Ocean Adventures snorkel costs $2 less for the same length but has no review history to compare. The Mola Mola trip costs about 4.5 times as much and adds a boat ride out of Langebaan on the Atlantic side.

Is the Great African Sea Forest snorkel in Cape Town worth it versus the other snorkel trips?

Yes if you want a guide who explains what you see and a small group: $73 for 2 hours with 4.9/5 from 140+ reviews, and 94% of English-speaking travellers gave a perfect score.

1.5 million international tourists spent almost R26 billion in the Western Cape in 2025, a quarter of the country's international tourism spend.

The price per hour is $37, almost the same as the other Simon's Town snorkel, so the premium is the biologist-led format and the data-collection role. The review summary scores the guide 4.9/5 and value for money 4.8/5.

• Worth it for: curious travellers who like marine biology and do not mind cold water.
• Worth it for: small groups who want a guided, shore-based snorkel without a boat.
• Not worth it for: anyone expecting tropical reef visibility or warm water; False Bay is 16 C.

When is the best time to go?

Reviews cover March to October, so the trip runs through the cooler half of the year, and the listing says it runs rain or shine.

The table gives Cape Town air conditions by month; Simon's Town is on the False Bay coast, so treat it as a guide for rain days and air temperature, not for water clarity or swell, which the data does not cover.

Reviewers snorkelled in March, May, July, August, September and October, and said the thick wetsuits handled the winter water. The sea sits near 16.1 C this week, and I have no monthly sea-temperature series I could verify, so I do not claim a best month for visibility.

For conditions on the day, the City of Cape Town runs a beach alerts site and a visitor section at capetown.gov.za. Upcoming public holidays are 4 November, 16 December and 25-26 December, from the Nager.Date API.

What do snorkellers say?

Reviews of the Cape RADD sea forest snorkel are almost uniformly five-star and centre on the guides, the marine life and the cold.

1. Guides - named guides praised for patience, knowledge and care for the whole group.
2. Marine life - sea stars, urchins, small sharks, a shark egg case and seals.
3. Briefing - a good briefing helped people see more under water.
4. Cold water - repeatedly mentioned; thick wetsuits cope, and warm clothes afterwards help.
5. Science - reviewers like the citizen-science angle and the conservation talk.

The sample is positive-only, so the cold-water comments are the main caution to take seriously.

Who should skip this snorkel?

Skip this snorkel if you want a boat trip, warm water or accessibility support, and look at the Cape Town boat tours instead.

• Anyone who wants a boat: there is none on this trip.
• Children under 10, pregnant women and people with mobility impairments: listed as not suitable.
• Weak swimmers: you need to swim or feel at ease in deep water.
• People who dislike cold water: expect about 16 C and a full wetsuit.
