About

Welcome to Castaway Island Hostel – Nusa Lembongan’s top rated tropical playground where backpackers, couples and digital nomads come together for the ultimate island escape!

Spread across 2000 mΒ² of lush gardens, we now offer something for every traveller. Choose from our famous social dorms (still only 28 beds for that perfect tight-knit vibe) or escape to one of our brand-new private bungalows – six stunning standalone villas with king-size beds, en-suite bathrooms, air-conditioning, mini-bar, coffee/tea facilities, and your own private balcony overlooking the brand-new second pool. Pure bliss after a day chasing manta rays!

Cool off and make friends at not one, but two incredible pools – including our legendary swim-up pool bar (ice-cold Bintangs served straight to your inflatable flamingo) and the brand-new crystal-clear pool tucked away in the private bungalow area for when you need a quieter dip.

Chill in our huge tropical gazebo packed with pool table, darts, giant Jenga, and bean bags. Every night is event night: movie nights under the stars, wild karaoke battles, pool competitions with prizes, daily happy hours, beer pong tournaments, and family dinners that turn strangers into lifelong travel buddies.

Adventure is literally on your doorstep. We organise the island’s best-value snorkelling trips (manta rays guaranteed most days!), scooter rentals, surf lessons, and fast-boat day trips to Nusa Penida’s epic viewpoints. Mushroom Beach is just a 2-minute walk, and sandy warungs even closer.

All the essentials (and more):
Free high-speed Wi-Fi everywhere
Powerful air-con in every dorm and bungalow
Swim-up pool bar + second private pool
Huge gazebo social hub
Lockers, hot showers, linen & towels included
On-site tour desk with the friendliest staff on the island (they’ll sort everything so you don’t have to!)
Whether you’re here to party with new friends, wake up to king-bed luxury in your private bungalow, or do a bit of both – Castaway Island Hostel is the only place on Lembongan with this perfect mix of social backpacker energy and upgraded private escapes.

Spots fill crazy fast. Book now and come see why hundreds of travellers call us their favourite hostel in all of Indonesia 🏝🍻

Short walk from mushroom beach ferry. Two pools which were good. 8 bed dorm rooms were boiling, considered sleeping outside as it was probably colder. Heard rats fighting in the ceiling above the bathroom. No breakfast and so maybe a bit expensive compared to other hostels in the area. Staff were nice.

Great hostel, second time I’ve been back to it now. walkable to mushroom beach but you’ll need a bike to go to the other side of the island.
