Best Time to Visit & Weather Tips
Bunaken National Marine Park experiences two distinct seasons that significantly impact your visit. Understanding these patterns helps ensure optimal conditions for your underwater adventures.
Dry Season (March-October)
The ideal time to visit Bunaken is during the dry season, particularly March through June and September through October. These months offer excellent visibility (often 30+ meters), calmer seas, and more reliable boat schedules. Water temperatures hover around a comfortable 28-29°C (82-84°F).
Rainy Season (November-February)
The rainy season brings occasional storms and reduced visibility. December through February sees the heaviest rainfall, which can disrupt boat schedules and underwater visibility. However, accommodation rates are lower, and you’ll encounter fewer tourists during this period.
Pro Tip: According to local dive operators, the absolute best months for underwater visibility and marine life encounters are April, May, and October. These shoulder season months offer ideal conditions without peak season crowds.
Getting Around Locally
Transportation within Bunaken National Marine Park revolves around boats, as the five islands (Bunaken, Manado Tua, Siladen, Montehage, and Nain) are only accessible by water. Here’s what you need to know about navigating this aquatic paradise:
Resort Boats
Most resorts operate their own boats for diving and snorkeling trips, typically included in tour packages. These scheduled departures visit popular sites around the islands and are the most convenient option for most visitors.
Public Boats
Public boats connect Manado to Bunaken Island daily, departing from Manado’s Calaca Harbor around 2-3 PM and returning from Bunaken around 8 AM. The fare is approximately 50,000 IDR each way (about $3.50 USD).
Charter Boats
For more flexibility, you can charter a private boat through your resort or local operators. This option allows you to customize your itinerary and timing, ideal for photographers or those wanting to explore less-visited sites.
On the islands themselves, everything is within walking distance. Siladen and Bunaken islands have simple paths connecting villages and resorts, though proper footwear is recommended as paths can get hot in the midday sun.
Need Transportation During Your Stay?
While boats are the primary transport in Bunaken, you might need a rental car for exploring Manado before or after your island visit.

Top Activities & Experiences
Bunaken National Marine Park offers world-class underwater experiences alongside relaxing island activities. Here are the must-do activities during your visit:
Wall Diving
Bunaken’s legendary vertical coral walls drop hundreds of meters into the deep blue, creating dramatic dive sites like Lekuan 1, 2, and 3. These walls are covered with colorful sponges, sea fans, and hard corals, attracting diverse marine life from tiny nudibranchs to pelagic species.
Snorkeling
The shallow reef tops make Bunaken perfect for snorkelers. Sites like Fukui Point and Timur offer excellent visibility and abundant marine life just meters from the surface. Expect to see countless reef fish, sea turtles, and vibrant coral gardens without needing scuba gear.
Turtle Watching
Bunaken is a sanctuary for sea turtles, with both Green and Hawksbill turtles frequently encountered. The protected waters around Siladen Island are particularly good for turtle spotting, with many residents growing to impressive sizes.
Island Hopping
Explore the five islands within the marine park, each with its own character. Manado Tua’s extinct volcano offers hiking opportunities, while Siladen’s pristine beaches are perfect for relaxation. Charter a boat for a day to visit multiple islands.
Dolphin Watching
The channels between islands are frequented by spinner dolphins and occasionally pilot whales. Morning boat trips offer the best chance to observe these playful mammals in their natural habitat, often performing acrobatic jumps alongside boats.
Beach Relaxation
Between underwater adventures, enjoy the pristine beaches found throughout the park. Siladen Island offers some of the most picturesque white sand beaches, perfect for sunbathing or watching spectacular sunsets over Manado Tua volcano.

Dining & Local Cuisine
The culinary scene in Bunaken blends traditional Minahasan flavors with fresh seafood and international options. Most visitors dine at their resorts, as standalone restaurants are limited on the islands.
Resort Dining
Most resorts offer full-board packages with three meals daily. The quality ranges from simple home-style cooking at budget properties to sophisticated cuisine at luxury resorts. Expect a mix of Indonesian specialties and Western options to accommodate international guests.
Local Specialties
Don’t miss Minahasan specialties like rica-rica (spicy chili-based sauce), ikan bakar (grilled fish with sambal), and cakalang fufu (smoked skipjack tuna). North Sulawesi cuisine is known for being among Indonesia’s spiciest, so request milder preparations if you’re sensitive to heat.
Village Warungs
In Bunaken Village, you’ll find small warungs (local eateries) serving simple, authentic meals at budget-friendly prices. These family-run establishments offer a taste of local life and cuisine, though menu options are limited and English may not be widely spoken.
Dining Tip: Fresh tropical fruits like mangosteen, rambutan, and snake fruit make perfect between-meal snacks. Most resorts offer fruit plates after diving or snorkeling sessions to replenish energy.
