Planning a diving holiday in Indonesia to one of the world's most pristine underwater paradises? Sienna Resort Maratua offers an unparalleled experience in the heart of the Derawan Archipelago, but getting there requires some preparation. This comprehensive checklist will guide you through every step of planning your Maratua dive resort adventure, ensuring a seamless journey from your first booking click to your final dive.

Reaching this remote paradise requires strategic planning. International travelers fly into Jakarta (CGK) or Bali (DPS), then connect to Berau (BEJ) via Balikpapan. Direct flights from Jakarta to Berau operate several times weekly. Coordinate your arrival time with Sienna's scheduled transfers—morning arrivals work best for same-day boat transfers. Build buffer time between connections, and consider an overnight in Berau if your flight arrives after 2 PM, as transfers to Maratua depend on daylight and sea conditions.

The journey from Berau to Sienna Resort takes approximately 2.5 hours by speedboat across the Makassar Strait. This transfer is included in all dive packages, with pickup from Berau Airport and boat departure from Sanggam Port. Morning departures offer calmer seas and better wildlife spotting opportunities. Our comfortable boats accommodate luggage, but pack strategically—soft-sided bags work better than rigid suitcases in boat storage. Sienna's team coordinates every detail, meeting you at Berau airport and handling baggage throughout the transfer.

Diving at Sienna Resort Maratua requires current certification from recognized agencies like PADI, SSI, or equivalents. Pack your physical certification card—digital copies aren't accepted underwater! Complete PADI's medical questionnaire before arrival. If you're over 45 or answer "yes" to any health questions, obtain a physician's dive clearance.

Sienna Resort provides well-maintained dive tanks, weights, and dive guide services included in your package. Dive equipment (BCD, regulators, wetsuits) is available for rental at competitive rates. However, many divers prefer personal masks and snorkels for comfort and fit. If you own a dive computer, bring it—familiarity with your own device enhances safety. Underwater photographers should bring cameras, housings, and ample storage. Bringing your own equipment eliminates sizing concerns, but renting is perfectly suitable for those traveling light. Nitrox-certified divers should bring their specialty card if planning enriched air dives for extended bottom times on Maratua's stunning wall dives.

Even if renting equipment, bring your own mask and snorkel—proper fit is crucial for comfort. Pack reef-safe sunscreen exclusively chemical sunscreens damage Maratua's delicate coral ecosystems. A personal rashguard or thin wetsuit provides sun protection during surface intervals. Don't forget your dive computer, extra batteries, and multiple memory cards for your underwater camera. The house reef's vibrant marine life deserves documentation!

Maratua's equatorial climate demands lightweight, breathable fabrics. Pack multiple swimsuits so you always have a dry option, broad-brimmed hats for sun protection, and polarized sunglasses for spotting marine life from the surface. Tropical-strength insect repellent protects during jungle walks to Kakaban Lake. Comfortable flip-flops serve as primary footwear, while water shoes help on rocky entry points. Bring a light jacket for breezy boat rides—spray and wind can create surprising chill. Take advantage of the complimentary kayaks and bicycles by packing appropriate activewear.

Carry your passport, photocopies stored separately, all dive certifications, and printed travel insurance documents. While Sienna Resort offers WiFi in common areas, connectivity is limited—embrace this rare opportunity for digital detox. Charge devices fully and bring backup power banks. A waterproof phone case protects during boat transfers and lets you capture above-water memories.

Leave heavy clothing and formal wear at home—Sienna Resort embraces casual tropical elegance. Single-use plastics contradict our environmental values bring a reusable water bottle we'll happily refill. The remote location means no shopping, so don't forget essentials like prescription medications or contact lens solution.
