Geographic overview of Opunohu Bay

Before we cover all the different activities, you should know something about its location and micro-climate.

Where is Opunohu Bay located?

Located in the northern part of Moorea Island, just 17 km (10.5 miles) northwest of Tahiti, this breathtaking Bay is one of the most stunning landscapes in French Polynesia.

Both the Opunohu Bay and Valley offer a blend of natural beauty and historical significance.

Mount Toheia, the island’s highest peak, reaches 1,207 meters (3,960 feet). You can see it in the background.

At the foot of this landscape lies Papetoai, a small and charming village with just 300 people.

The Bay is more than just a scenic destination. It’s a gateway to the Ōpūnohu Domain, an area dedicated to ecotourism.

Climate and weather patterns

The region has a unique microclimate, making it a haven of biodiversity.

The Opunohu lagoon has depths ranging from 15 to 50 meters (49 to 164 feet) and is surrounded by the valley, which receives an average rainfall of 2,500 to 3,500 mm (98 to 138 inches) annually.

This rainfall nurtures the fertile valley, making it the island’s primary FRESHWATER RESERVOIR.

The valley is a natural and historical treasure, featuring over 500 recorded ruins and sacred sites (called marae).

Locals often refer to this area as Moorea’s “lung,” showing its role in sustaining the island’s unique ecosystem (there is even an agricultural college studying Moorea’s unique ecosystem).

But why is Opunohu Bay so famous?

Natural attractions of the Bay

Opunohu Bay has many natural wonders, from ancient cultural sites to white sand beaches, forests, and marine ecosystems.

Let’s take a closer look at each of them.

1) Ancient marae and cultural heritage

As you hike deeper into the Opunohu Valley, you’ll follow an ancestral trail filled with ancient marae, or Polynesian ceremonial sites.

There are HUNDREDS of these preserved ruins along the trails.

INSIDER TIP: The most striking marae are along the AFAAHITI Trail, a moderate hike that blends history with stunning natural surroundings. Bring a guidebook or join a local tour to uncover the deeper meanings behind these sacred sites.

2) Turquoise waters and beaches

Opunohu Bay is not known for its sandy beaches, but the immediate shoreline features a narrow strip of coastal forest between the road and the lagoon.

While the area focuses more on ecological preservation than beach lounging, there are small, sandy patches where you can relax or enjoy the view.

One of the best ways to enjoy Opunohu Bay is by joining a half-day snorkeling lagoon tour from Corallina Tours.

After they pick you up from your hotel, they will leave Opunohu Bay to look for spinner dolphins, sharks and rays.
