Manta Bay

If there’s one marine encounter that leaves travelers speechless in Nusa Penida, it’s swimming alongside the majestic manta rays of Manta Bay. Located just off the island’s southwestern cliffs, this iconic snorkeling spot has become world-famous for its year-round population of reef manta rays, graceful giants that glide effortlessly through the crystal-clear waters.

In this article, we’ll cover everything you need to know about Manta Bay Nusa Penida — from what makes it unique, when to go, how to get there, and why it’s one of the most unforgettable snorkeling experiences in Indonesia.

What Is Manta Bay?

Manta Bay is a shallow coastal area with rocky coral formations and nutrient-rich currents, which attract large numbers of plankton — the favorite food of manta rays. These gentle creatures, some reaching up to 5 meters (16 feet) in wingspan, visit the bay regularly to feed and sometimes even to get cleaned by smaller fish.

Unlike diving spots where mantas stay deep, Manta Bay is shallow enough (around 5–12 meters) that you can see them clearly while snorkeling at the surface. This accessibility makes it one of the few places in the world where you can snorkel with manta rays without scuba gear.

Why Manta Bay Is So Special

There are many beautiful reefs in Bali, but few can offer what Manta Bay does:

• Consistent sightings: Mantas are seen almost daily thanks to the rich plankton supply in the bay.

• Close encounters: Because they swim near the surface, you can observe them closely — even without diving down.

• Scenic surroundings: The cliffs surrounding the bay make the approach by boat breathtaking, with jagged limestone formations rising dramatically from the sea.

• Beginner-friendly: No need for diving certification — just mask, snorkel, and fins.

Seeing a manta ray glide beneath you, often circling back around with curiosity, is a humbling and surreal experience. Many visitors say it’s the highlight of their trip to Bali.

What Kind of Manta Rays Will I See?

The rays you’ll most likely encounter at Manta Bay are reef manta rays (Mobula alfredi). Unlike the larger oceanic mantas, these are slightly smaller but still incredibly impressive. They are harmless, have no stingers, and are known to be playful and curious around humans.

Fun fact: Each manta has a unique spot pattern on its belly — just like a fingerprint!

Is Snorkeling at Manta Bay Safe?

Yes, as long as you're with a trusted tour operator. At Discover Nusa Penida, we ensure all our snorkeling trips to Manta Bay are guided by experienced locals who monitor sea conditions closely.

While currents can be strong, your guide will choose the best time to snorkel and will be in the water with you for safety. Life jackets are available for all participants, and snorkeling equipment is provided.

You don’t need to be an expert swimmer, but a basic comfort level in the water helps. We also recommend listening closely to your guide’s briefing before entering the water.

When Is the Best Time to Visit Manta Bay?

Manta Bay is one of the few places in the world where manta rays can be spotted all year round. However, the best conditions for snorkeling are during the dry season, from April to October, when the sea is calmer and visibility is higher.

The morning hours (between 7 AM and 11 AM) are generally best, as the water tends to be clearer and mantas are more active.

Note: Since manta sightings are a natural phenomenon, there’s never a 100% guarantee — but the chances are excellent, especially when traveling with experienced guides who know the patterns and currents.

How to Get to Manta Bay

Manta Bay is accessible only by boat. Most snorkeling tours depart from Toya Pakeh or Banjar Nyuh Harbor on Nusa Penida and reach the site in about 20–30 minutes.

If you're coming from Bali, you’ll take a fast boat from Sanur (30–45 minutes), then join a snorkeling tour either directly from the harbor or as part of a Nusa Penida snorkeling package.

At Discover Nusa Penida, our snorkeling tours include:

• Round-trip fast boat from Bali (optional)

• Hotel pickup & drop-off

• Snorkeling equipment (mask, fins, life jacket)

• Local boat & guide

• Underwater GoPro photos/videos

• Lunch (on full packages)

What to Expect During the Snorkeling Trip

Once your boat reaches Manta Bay, your guide will scout the area for manta activity. If conditions are right, you’ll be briefed and helped into the water in small groups. Here's what you can expect:

1. Crystal-clear water and views of the ocean floor

2. Mantas circling or gliding past just meters below you

3. A mix of other marine life, such as parrotfish, clownfish, and even turtles

4. Floating time of around 30–45 minutes (or longer, depending on sea conditions)

Sometimes, multiple mantas may swim together, creating a surreal underwater ballet. You’re not allowed to touch them, but just observing is magical enough.

What to Bring

• Swimsuit

• Towel

• Sunscreen (reef-safe recommended)

• Waterproof bag or dry bag

• Change of clothes (after snorkeling)

We provide all snorkeling gear, drinking water, and optional snacks or meals depending on your tour type.

Manta Bay vs. Manta Point – What's the Difference?

A common question is whether to visit Manta Bay or Manta Point. Both are manta habitats near Nusa Penida, but they differ in experience:

• Manta Bay: Better for snorkeling; shallower and more beginner-friendly

• Manta Point: A deeper dive site, more suited for scuba divers; fewer snorkel trips go here due to rougher sea

Unless you’re a certified diver, Manta Bay is the ideal place for most travelers looking to have an up-close encounter with mantas.

Responsible Snorkeling With Mantas

At Discover Nusa Penida, we promote eco-conscious marine tourism. When snorkeling with manta rays:

• Do not touch or chase them

• Keep a respectful distance

• Avoid sudden movements

• Use reef-safe sunscreen

• Never leave trash or plastics in the water

By following these simple rules, you help protect the mantas and their environment for future generations.

Combine Manta Bay With Other Spots

Many of our tours to Manta Bay also include stops at other amazing snorkeling sites such as:

• Gamat Bay – rich coral and fish diversity

• Wall Point – vertical coral cliffs and shallow reef

• Crystal Bay – a relaxing swim with great visibility

You can also choose a Snorkeling + Land Tour Combo, visiting Manta Bay in the morning and exploring Kelingking Beach or Angel’s Billabong in the afternoon.
