About Lombok

January-March is the sweet spot: surf south coasts, trek Rinjani foothills, and island-hop Gili day trips. Dry months suit reef and volcano plans without peak humidity.

Travel Tips

Gili Boat Timing
Fast boats to the Gilis leave mornings from Bangsal or Senggigi areas - seas roughen later. Rinjani treks need early trailhead starts.
Airport & Island Roads
Airport transfers to Kuta Lombok or Senggigi take time on winding roads. Scooter hire is common; wear helmets and avoid night mountain rides.
Park & Boat Fees
Rinjani park permits and guide fees are mandatory for summit routes. Island boats include or add conservation fees - ask before paying.
Conservative Beach Areas
Some villages prefer modest swimwear cover-ups off the sand. Reef shoes help on coral fragments; strong currents occur on south coasts.
