Traveler Tips & Experience — Insider Advice
🌊 Sea Conditions & Safety
- Speedboat crossings are weather-dependent. The best conditions are May–October (dry season). November–April can bring rough seas; always check the forecast from BMKG.

- If you're prone to seasickness, take medication 30 minutes before boarding. The Sunda Strait can be choppy.
🧳 Luggage & Baggage
- Speedboats have limited luggage space. Max 15–20 kg per person is standard. Excess bags cost 50,000–100,000 IDR (3.5–7 USD) each.

- Consider using Takkyubin (行李快递) if you have bulky luggage. Some hotels in Bandar Lampung offer luggage forwarding to the airport.
🚕 Transport & Navigation

💰 Money & Payments
- Most speedboat operators and taxis accept cash only (Indonesian Rupiah). ATMs are available at Bakauheni Port, but fees apply.
- For charters, you can often pay via bank transfer or e-wallet (GoPay, OVO) if booked online.
