Giant manta rays in Bali’s blue water sounds like a movie scene, and this day trip tries hard to make it real. You start in Sanur and head by fast boat to Nusa Lembongan for three snorkeling stops, with a mangrove forest segment to balance the action.

I like that the trip feels built for real comfort: pickup and drop-off are included in a wide area, and you get full snorkel gear plus life vest/life rings. I also like the mix of sites—Manta Bay for the big moment, then clearer-water snorkeling at Crystal Bay and the Toya Pakeh Wall zone.

One thing to keep your expectations honest: manta rays are high-probability, but sightings aren’t guaranteed because animals follow the conditions, not your schedule.

Key things I’d bookmark before you go

• Manta Bay is the centerpiece, with the highest chance of spotting manta rays during the snorkeling window.
• Three snorkeling sites in one day (Manta Bay, Crystal Bay/Gamat Bay, Toya Pakeh Wall) means you’re not only chasing one species.
• Safety support for non-swimmers: life vests/life rings and snorkeling guides are part of the plan.
• Gear and small comforts are included: mask, snorkel, fins, shower, towel, locker, and even snorkel photos/videos.
• A slower mangrove stop follows the water time, giving your body a break before the fast boat back.

Sanur to Nusa Lembongan: the day’s pace and why it works

The whole day runs about 7 to 8 hours, and it starts with a check-in at Matahari Terbit Port in Sanur around 07:45. You’ll wait about 30 minutes before the fast boat departs, so I suggest you use that time to get calm, hydrated, and ready to move.

From there, it’s a speedboat ride over to Nusa Lembongan. This matters because it keeps your time in the water from getting eaten up by long transfers. And once you’re on the island side, the snorkeling stops are close enough that the day feels tightly planned instead of scattered.

One practical note: the tour can host up to 70 travelers, so expect a group feel. That’s not a deal-breaker, but it can mean a bit of waiting when you switch locations, check in with the guide, or gear up.

The fast boat route: what to expect on the water

The included transfer is fast boat Sanur ↔ Nusa Lembongan, which is a big part of what you’re paying for. Speedboats are the reason you can fit three snorkeling sessions plus the mangrove portion into one day.

You’ll typically arrive at Jungut Batu Port on Lembongan after leaving Sanur. Then the group moves on to the snorkeling sites, and later you return through Sanur for your hotel drop.

If you’re sensitive to boat motion, this is the part of the day you’ll want to take seriously. You don’t have to guess what to do—just plan ahead so you stay comfortable when the engine noise and water movement start.

Manta Bay snorkeling: your best shot at giant rays

This is the reason most people book: Manta Bay. The tour schedule gives you about 30 minutes in the water here, and this is the main area where you’re looking for giant manta rays.

Here’s the honest truth that helps you enjoy the day: manta rays are in their natural habitat, so the presence of mantas depends on environmental factors. The tour notes a high chance, but it still isn’t a guarantee. I actually think this clarity is useful—you can show up excited without turning the day into a stress test.

What you should do with that reality? Go for the whole experience, not only the checklist. Even on days when mantas are fewer, you still have a chance at other marine life, and the water at this type of site is often the main attraction by itself.

Also, Manta Bay can get a little crowded. My practical tip: if you’re not super comfortable floating, use the included life vest/life jacket rather than trying to freestyle your confidence. It buys you calm breathing time so you can focus on what’s around you instead of how you feel in the water.

Crystal Bay and Toya Pakeh Wall: clear water and more than one kind of critter

After Manta Bay, you’ll move to Crystal Bay for another 30-minute snorkeling window. The description leans on what you’ll care about as a snorkeler: very clear sea water and a site with cliffs and steep slopes. Translation: it’s designed to look good, and visibility is often the difference between seeing “a few fish” and actually enjoying what’s under you.

Then the day continues to the Toya Pakeh Wall area (listed as “Lembongan ocean trip penida” in the schedule). This stop highlights invertebrates hiding in cracks, plus bigger, interesting animals like giant moray eels and octopus. You’ll also have a good chance of seeing schools of fish such as sweetlips, red-tooth trigger fish, and batfish.

Two ways these stops make your day better:

1. If mantas don’t show up in force, you’re not stuck with a “maybe later” feeling. You’ve got other targets and habitats.
2. The variety helps you enjoy the water even if you only get a quick look at the biggest animals.

Time is still time, though. Each snorkeling stop is about 30 minutes, so you’ll want to snorkel efficiently. Put your gear on quickly, listen to your guide’s safety instructions, and don’t burn your energy racing around when you could spend those minutes calmly observing.

Mangrove Forest by boat: the good reset after open water

Between the snorkeling and the return ride, you’ll do a mangrove stop for about 30 minutes. The tour schedule lists a traditional boat route so you can observe spectacular mangrove roots and wildlife that live in the forest.

This part works for a couple reasons. First, it gives your arms and lungs a break after time in salt water. Second, mangroves are the kind of environment where you can slow down and watch instead of chasing movement.

The overall description also mentions exploring the mangrove area by kayak, so it’s worth confirming the exact setup on the day you go. What you can count on from the schedule: you’ll spend around half an hour in the mangrove zone, and the focus is on viewing the roots and the animals that call the forest home.

Lunch, showers, lockers, and the small stuff you’ll feel later

On paper, snorkeling tours often list gear and a meal. In real life, the difference is the details.

This one includes:

• snorkel gear (masks, snorkel, fins, life vest, life rings)
• a towel, shower, and locker
• a traditional Indonesian lunch
• snorkeling photos and videos
• a guide and insurance coverage

Why you’ll care: once you’re done in the water, you’ll want to wash off without improvising. A locker and shower turn “I’ll deal with it later” into “I feel human again.” And photos/videos can be helpful because the best manta moments can happen faster than your camera can.

Lunch being included also means you won’t be hunting for food at the exact wrong time. If you’re someone who gets cranky when hungry, this matters.

Pickup, drop-off, and getting to the start without drama

Pickup is a big part of the value. Free pickup/drop-off is listed for Kuta, Legian, Seminyak, Petitenget, Jimbaran, Nusa Dua, Sanur, and Denpasar. Outside that zone (for example Ubud, Canggu, Tanah Lot, Uluwatu) there’s an additional charge: IDR 450,000 per car return.

This affects your actual cost, not just your headline price. If you’re staying outside the free zone, that extra car fee can change the math—so check where your hotel sits before you commit.

The tour’s meeting point is at Arthamas Express Fast Boat, Pertokoan Arcade, Jl. Matahari Terbit No. 4, Sanur Kaja, Denpasar Selatan, Bali. If your pickup isn’t included, you’ll want to plan to arrive early enough to handle parking or getting to the port.

The $67.95 price: is this a good value day?

At $67.95 per person, you’re paying for far more than just the snorkel time. You’re also paying for:

• fast boat transfers between Sanur and Nusa Lembongan
• snorkeling equipment
• guide support and safety gear
• a three-stop snorkeling plan
• lunch
• and the mangrove segment

A lot of Bali “manta” experiences get expensive fast once you add gear rental, transport, and a meal. Here, those basics are already included, which makes it feel more like a complete day.

The value calculation gets even better when you consider the group size cap of up to 70 travelers. That’s not tiny, but it’s still large enough that costs can be spread across the day’s logistics without it turning into a chaotic free-for-all.

My one caution on value: because manta rays aren’t guaranteed, you’re really buying the opportunity plus the broader snorkeling plan. You’ll feel like you got your money’s worth if you’re excited about the entire underwater scene, not only one species.

Who this tour suits best (and who should think twice)

This is a strong fit if you:

• want a single-day plan from Bali that includes transfers and gear
• care about marine life and want multiple snorkeling chances
• want safety support even if you’re not a confident swimmer (the tour states that non-swimmers can snorkel with safety equipment and guides)

It might be less ideal if you:

• need a guarantee to feel satisfied. The tour is clear that manta sightings depend on conditions.
• dislike speedboat rides. The day is built on the fast boat, so motion is part of the experience.

The snorkeling windows are also shorter by design—around 30 minutes each. If you prefer long water time with lots of independent exploring, you might feel the schedule is tight.

Should you book this manta ray snorkel day trip from Bali?

If you want a well-organized day that gives you a real shot at manta rays while still delivering snorkeling variety, I think this is a solid booking. The combination of gear, safety support, included lunch, and the added mangrove forest stop makes it feel like a full experience instead of only a “one minute in the water” stunt.

Book it if your goal is to see manta rays and enjoy the underwater ecosystem around Nusa Lembongan. Consider booking something else if you’re the kind of person who will feel disappointed unless mantas show up for sure.

If you do book, pack smart: comfortable clothes and change of clothes, comfortable footwear, sunscreen, and bring cash or a card for any self-expenses. And when you hit Manta Bay, take the safety gear seriously—calm snorkel time lets you actually enjoy what you came for.
