Swimming is generally safe at Gili Trawangan, particularly on the calmer east and south coasts. The west coast can have stronger currents, especially during low tide. There are no lifeguards on duty, so swim cautiously and stay aware of conditions. The waters are clear with good visibility for snorkeling. Be mindful of boat traffic near the main harbor area. Strong currents between the Gili islands make swimming between them dangerous. Always check local conditions and avoid swimming alone or after consuming alcohol at beach parties.

Gili Trawangan is visitable year-round with tropical weather. The dry season (May to September) offers the best conditions with minimal rainfall, calm seas, and optimal diving visibility. Peak tourist season runs June through August and around Christmas/New Year. The wet season (November to March) brings occasional afternoon showers but also fewer crowds and lower accommodation prices. April and October are shoulder months with good weather and moderate crowds. Sea conditions are calmest May through September, ideal for water activities.

Gili Trawangan has no airport or motorized vehicles. Access is by boat only. Fast boats depart from Bali (Padang Bai, Serangan, Sanur) taking 1.5-2.5 hours, or from Lombok (Bangsal Harbor, Teluk Nare, Senggigi) taking 20-45 minutes. Public ferries run from Bangsal Harbor on Lombok. Once on the island, transportation is by foot, bicycle (rental available), or cidomo (horse-drawn cart). There's no parking as no cars are permitted. Book boat tickets in advance during peak season.

Gili Trawangan offers diverse accommodation from budget hostels to luxury resorts, concentrated along the east and south coasts. The main strip has numerous restaurants serving Indonesian, Western, and international cuisine, including beach clubs and sunset bars. Fresh seafood is widely available. Beachfront warungs offer local dishes at lower prices. Several beach clubs provide day beds, pools, and dining. Small convenience stores and ATMs are available, though cash is preferred. Book accommodation ahead during peak season as the island fills quickly.

Gili Trawangan is known as the party island of the three Gilis. Each night, different beach bars host parties rotating around the island—locals call it the 'party schedule.' Monday and Thursday nights are typically biggest. Beach parties feature live DJs, fire shows, and dancing on the sand until late. The main strip along the southeast coast has the most bars and clubs. Despite the party reputation, quieter accommodations exist on the north and west sides. The atmosphere is relaxed and backpacker-friendly with reasonably priced drinks.
