Swim and Snorkel with Seals. Boat Trip Penzance Cornwall

Seals can be curious up close. What makes this trip special is the combination of a 7-meter RHIB ride and a wildlife spotting guide who helps you find the good stuff around Mounts Bay. You’re not stuck watching from shore, you’re out on the water with a clear 360-degree ocean view.

Two things I really like are the guide-led wildlife scanning on the way out and the chance to snorkel with seals in their natural spot. The main drawback to plan around is conditions, because the Atlantic can feel cold even in summer, and some days the water can be choppy or a bit murky.

Key things to know before you go

• 7-meter RHIB, 360-degree views from Penzance harbour to the snorkel area
• Small group up to 6 means you get more attention and better coordination
• About 1 hour snorkelling with a qualified snorkel guide in the water
• Grey seals often join and may come up very close, even nibbling fins
• You must bring full-length wetsuit gear or hire it in advance (5mm options available by arrangement)

Finding Your Way To Penzance Sailing Club (TR18 2LL)

This tour starts in Penzance harbour. If you’re driving, park in the big harbour car park and head to the corner. You’ll see a fenced compound with boats inside. Walk behind the compound, and you’ll find Penzance Sailing Club, where you meet your group.

I like this meeting setup because it’s straightforward and you’re not trying to guess which pier a boat is tied to. Also, the harbour area is usually easy to orient once you see the compound and the sailing club behind it.

Since hotel pickup is not included, plan to get yourself there with time to sort gear, wetsuit, and anything you need for warmth before you board.

The Mis Me RHIB Ride, 360 Views, and Wildlife Spotting

Your boat is the Mis Me, a 7-meter RHIB. The trip out and back is about one hour each way, with wildlife spotting breaks as you head into Mounts Bay toward your snorkel site.

This is one of the best parts of the whole experience, even if you’re mostly there for the seals. From the RHIB you get that wide-open ocean feeling, and you can scan for movement all around. In at least one case, the trip started with dolphins staying close to the route, and that kind of early sighting sets the tone.

On this ride, guides focus on spotting. In one review, Andy and his companion drove the group to the most exciting areas without overdoing disturbance. You’re not just being taken to a location, you’re being helped to understand what you’re seeing, like how and where to look when birds are circling or when surface action pops up.

One practical note: if you sit toward the back of the boat, holding on can get tiring. The RHIB moves fast and can roll a bit at speed, so bring a sense of humor, grip the rails, and expect spray.

Snorkelling With A Qualified Guide, Seals Up Close

The snorkel time is about one hour, and you’ll be in the water with a qualified snorkelling guide. That escort matters. It means you’re not left to figure out the rhythm of snorkeling in a marine environment while also trying to interpret animal behavior.

Grey seals are common on these trips, and that closeness is the whole point. In the field, seals can be bold. You might experience them coming up near you, getting curious, and yes, even nibbling fins.

What I appreciate here is the balance between excitement and control. The guide approach is there for safety and for responsible wildlife interaction. You’re still getting that wild, close-up feeling, but you’re not turning the experience into chaos.

Under the water, what you see can change a lot day to day. One positive account described clear moments with seals in a bay, while another mentioned trouble seeing underwater clearly due to water clarity and choppy conditions. That means your expectation should be flexible: you’re going for the chance at seal encounters, plus whatever else appears.

Also, even when it sounds calm, you must be able to exit via a boat ladder. That part is not optional. If you’re not comfortable climbing out with gear on, the water time won’t feel good.

What Happens On The Water, Step By Step

Here’s the pacing you can expect in practical terms:

First you board in Penzance harbour, then you head out across Mounts Bay. You’ll keep an eye out for whales and dolphins along the way, and the guide will help you scan for birds too.

Then you arrive at the snorkel site and switch from wildlife spotting to underwater focus. You’ll snorkel for roughly an hour, staying close to your guide.

After snorkelling, you return on the boat, again taking about an hour. If wildlife is active, you may get more sightings on the return route, including fish sightings that show up near the surface.

The ride length and snorkel timing add up to a tight 3-hour experience. If you like adrenaline plus nature, this format works well. If you prefer long, slow, relaxed time in one place, you may find the pacing a bit intense because you’re traveling both ways for about an hour each.

Wildlife Possibilities: Dolphins, Seals, Whales, and More

This trip sells the idea of marine wildlife, and it delivers that theme in more ways than one. The ride route and snorkel area are set up to spot animals at the surface and in the water.

Based on what you could realistically encounter, keep an open mind about species like:

• dolphins and porpoises
• seals
• whales
• sunfish
• birds

What you might not get is perfect underwater visibility. One strong review noted that the underwater view wasn’t ideal due to turbidity, even though the surface wildlife moments were still fantastic. On another day, snorkeling conditions were choppy, with foam in the water, and visibility was difficult.

That doesn’t mean the trip is bad, it means you should judge it like a wild, weather-dependent activity. Your best strategy is to focus on the moments you can actually see, surface behavior, and how animals react to the area, rather than assuming you’ll always get crystal-clear reef-style snorkeling.

Cold Atlantic Reality, Wetsuits, and What To Bring

This is a cold-water snorkeling experience, even in mid summer. The Atlantic can feel quite chilly on the water, and that’s why a full-length wetsuit is required. Shorties are not sufficient.

You should also plan for the fact that you will likely get sprayed. Warm clothing over your wetsuit helps, because after you’re in the water you’ll cool down quickly during the boat ride.

What to bring:

• warm clothing
• sun hat
• sunscreen
• water

For snorkeling equipment, you provide your own snorkelling gear and a full-length wetsuit. If you don’t have the right kit, you can hire snorkeling equipment including 5mm wetsuits by prior arrangement. You’ll need to contact the operator to check prices and availability before you book, since it’s not described as automatically included.

If you’re thinking, I’ll just wear a T-shirt under the wetsuit, I’d reconsider. The cold factor and the spray factor are real here.

Who Can Do This Trip (And Who Should Skip It)

This tour has clear physical requirements, and they’re there for a reason. To join, you must be able to:

• swim
• be very water confident
• ride on the boat for up to an hour
• exit the water via a boat ladder

The minimum age is 11. Under 16s must be accompanied in the water by an adult.

It is also not suitable for people over 250 lbs (113 kg). That restriction matters for ladder entry and exit and for keeping everyone safe and comfortable on the water.

If you want seals close but you’re not a strong swimmer or you hate the idea of climbing out a ladder, this is not the right format for you. Choose a shore-based wildlife trip instead, or look for an activity that doesn’t require ladder exit.

Group Size, Pacing, and Comfort On a Fast Boat

The group is small, limited to 6 participants. I like that because it usually means:

• the guide can manage pacing and safety without juggling too many people
• you’re more likely to get time with the guide during the snorkel period
• less crowding in and around wildlife

The pace is also practical. You’re not spending a whole afternoon changing locations. This is about one snorkel session plus the in-between wildlife scanning during the rides.

Comfort is a mixed bag because it’s a RHIB. Expect to hold on and expect spray. If you’re prone to motion sickness, this is something to take seriously. One review noted fatigue holding on during the high-speed ride, which is a good heads-up for anyone who isn’t used to fast boat travel.

Price and Value: Is $128 Worth It?

At about $128 per person for a 3-hour experience, you’re paying for three things at once:

1. a guided RHIB boat trip that’s focused on wildlife spotting
2. a qualified snorkelling guide in the water
3. a dedicated snorkel session of about one hour

Small-group size and the requirement that staff manage safety on a ladder-exit snorkeling setup also add value. It’s not a passive wildlife cruise. You’re doing an active water experience, with the chance of close seal encounters and a real chance of other marine life too.

Where value depends is on conditions. If you get a day with good visibility and calm enough water, it can feel like a dream snorkel. If the water is murky or choppy, you may still enjoy the surface wildlife moments, but the underwater view might be less impressive.

One review even mentioned a stomach bug after the trip, and they couldn’t be sure whether it was related to water quality or foam. I can’t confirm anything about that, but it’s a reminder that sea conditions vary. Bring the mindset that this is wild water, and protect yourself by staying sensible with what you expose yourself to.

Practical Tips That Improve Your Chance of a Great Day

Here are the things that make the experience more likely to feel worth it:

• Get your wetsuit right: full-length is required, and you may need warm layers over it.
• Be ready for spray: bring sunscreen and a sun hat. Keep your eyes protected and your posture comfortable while holding on.
• Practice ladder confidence before you commit: if you’re unsure, talk to the guide when you arrive so they can explain what they need from you.
• Bring your own snorkel kit and check the fit so you’re not fiddling during briefing.
• Stay flexible about visibility: if the water is murky, shift your attention to surface cues and the guide’s scanning for animal movement.

If you’re the type who gets frustrated by imperfect visibility, that’s the biggest mental hurdle for this trip. The payoff is close-up seal energy and a guided marine experience that you can’t easily recreate on your own.

Final Verdict: Should You Book Swim and Snorkel With Seals From Penzance?

I think this is a great choice if you want a small-group, guided snorkelling experience with a strong likelihood of grey seals and the chance of other marine wildlife around Mounts Bay. The RHIB ride is a real part of the fun, and having a qualified snorkel guide in the water helps you feel safer and more present.

You should pause and reconsider if cold water, spray, choppy conditions, or ladder exit sounds like your personal worst day. Also, if you’re expecting consistently clear underwater views, go in with flexibility.

If you’re water confident and genuinely excited by the idea of seals coming close, this tour can be a memory you’ll think about long after you’re back on land.
