No-markup version: ~£905 per person

Estimate only, not a guaranteed price. Always verify costs independently before booking.

A self-launched 18-day Indonesia route that replicates G Adventures' "Sumatra to Nusa Lembongan" trip: Medan's colonial and culinary sights, an orangutan trek and river tubing in Gunung Leuser National Park from Bukit Lawang, a flight to Bali for surf lessons in Canggu, Ulun Danu Beratan, a northern Bali guesthouse stay in Bulian, sunrise on Mt Batur with hot springs, Ubud's spiritual side and the women's community project lunch, finishing with seaweed farms, clifftop sunsets at Devil's Tear and beach days on Nusa Lembongan. Everything is booked direct or via GetYourGuide/Klook and done on local buses, shared shuttles, budget flights and fast boats — for roughly a third of the operator's price. All costs are approximate per person and exclude international flights.

Gunung Leuser jungle trek & overnight camp

Gunung Leuser National Park

The big one. Head out at 8am with your guide into Gunung Leuser National Park — one of the richest rainforests in Southeast Asia and home to wild Sumatran orangutans. Expect 5-7 hours of trekking with a picnic lunch, scanning the canopy for orangutans, Thomas's leaf monkeys, long-tailed macaques, giant monitor lizards and hornbills. Your porters set up camp by a river; dinner is cooked over the fire by your guide. Sleeping under a tarp with the jungle soundtrack is the whole point — bring a headtorch and leech socks if you have them.

Frequently asked questions

How much does Sumatra to Nusa Lembongan: Self-Launched Wild Islands & Zen Beaches cost?+

Doing it yourself with this self-launched itinerary costs an estimated £905 per person for 18 days in Indonesia (Sumatra & Bali). This is an AI-generated estimate based on typical budget-traveller prices — actual costs will vary by season and how you book.

Is this cheaper than booking with G Adventures?+

Yes — G Adventures charges around £1,580 per person for a similar tour. Doing the same route independently, using the same standard of accommodation and activities, costs an estimated £905 — a saving of roughly £675 (43%) per person.

How long is the Indonesia (Sumatra & Bali) trip?+

This itinerary runs 18 days, covering 18 day-by-day stops through Indonesia (Sumatra & Bali).

How do I join this trip?+

You can join an existing open departure using this itinerary if one is scheduled, or launch your own departure with your own dates and invite other travellers to join you — no tour operator required.

Isn't it easier to just use a tour operator?+

Well, yes, a tour operator will book all the individual parts of your travel for you and provide a guide. That's obvious, but doing this has the potential to save the group thousands, which can in turn improve your itinerary substantially or save you huge amounts of money. Also, when you launch a departure, Travel Crew has tools in place to help you book the individual sections of the trip or make it easier for you to do this as a group. Really, you do not need a middle man. If you are more comfortable paying more and using a middle man, then you should certainly do this.

Is it safer to book through a tour operator?+

Arguably, there isn't much difference. A self-launched trip runs on the same principle as a group travel crew: collective responsibility, everyone looking out for each other, the same way it would if a group of friends organised the trip themselves — because that's exactly what's happening. You should always take out travel insurance before you go, self-launched or not; that doesn't change either way. Every open departure is published publicly with real dates and a real trip organiser, so it's never an anonymous arrangement, and our support team is reachable any time you need help, including in an emergency while you're away. Longer-term, we're building direct relationships with ground DMCs in popular destinations, offered as an optional paid add-on for extra on-the-ground support. Ultimately, though, the group is responsible for its own conduct and safety on a self-launched trip, same as on any trip you plan yourself.

What kind of trip is this?+

This is a adventure, culture, beaches trip through Indonesia (Sumatra & Bali), self-launched rather than run by a tour operator — you organise it with a group you find or bring yourself.
