May is a great month for Bumbang Island day-trips — calm crossing, improving snorkel viz, low boat prices, and you'll be the only visitors on the islet most days.
Bumbang Island in May is a quiet day-trip target from Tanjung Luar. The early dry season delivers calm sea for the 30-45 minute boat crossing, snorkel visibility on the surrounding reef pushes 12-18m, and the uninhabited islet has its coral reefs and occasional reef shark sightings essentially to itself. Boat charter from Tanjung Luar runs 500k-1.2M IDR depending on group size.
# Bumbang Island in May: The Quiet East Lombok Snorkel Day-Trip
Bumbang Island (Pulau Bumbang) is a tiny uninhabited islet off east Lombok's coast, reached by a 30-45 minute boat ride from the main fishing port at Tanjung Luar. It's one of the lesser-known snorkel day-trip destinations on Lombok, well off the standard Trawangan-Meno-Air circuit, with healthy coral, regular reef shark sightings, and almost no other visitors. May is a strong month to visit — the early dry season smooths the boat crossing and the snorkel visibility starts climbing back from wet-season lows.
Bumbang Island sits in the Alas Strait off east Lombok, roughly 30-45 minutes by traditional boat from Tanjung Luar fishing port. It's a small uninhabited islet — perhaps 100-200 m across — with a small beach landing on one side, low scrub on top, and coral reef extending out from all sides.
The islet itself has no infrastructure, no buildings, no fresh water, no permanent inhabitants. It's used occasionally by local fishermen as a day-rest stop and visited by a small number of snorkel day-trippers from Tanjung Luar. The character is genuinely remote — you'll often be the only visitors there for the entire day.
May sits at the cusp of dry season on Lombok, delivering favorable conditions for Bumbang Island trips:
May is the easy entry month for this destination. Conditions are favorable across all variables and the prices haven't bumped up to peak levels.
Tanjung Luar is east Lombok's main fishing port, about 90 minutes drive east of Mataram or 75 minutes from Kuta Lombok. It's a working Sasak and Bugis fishing community with a busy harbor full of traditional wooden boats, a fish market that operates daily, and a slightly rough-edge atmosphere that's different from anywhere else on Lombok.
To charter a boat to Bumbang Island, walk to the harbor and ask any boat captain you see. Negotiate directly — a private day-trip charter for 4-6 people runs 500-800k IDR including fuel in May, significantly cheaper than booking through agents in Senggigi or Kuta (1.5-2.5M IDR). Public boat seats are not really a thing for Bumbang specifically; most trips are private charters.
The crossing takes 30-45 minutes depending on conditions. The boats are simple wooden craft with a small sun cover, basic seating, and sometimes a basic toilet. Expect to get wet from spray on the bigger swell days — bring a dry bag for electronics.
The reef surrounding Bumbang Island offers genuinely good snorkeling for this part of Lombok. Specific May conditions:
The reef shark sightings are the headline draw. Local boat captains know exactly where the sharks tend to be and will time your snorkel stops accordingly — typically the outer reef on the eastern side of the islet.
For divers, dive operators in Kuta and Senggigi occasionally run day trips to Bumbang for advanced divers, but the standard offering is snorkel-based. If you want to dive, arrange specifically with a Kuta operator several days in advance.
A typical Bumbang day-trip looks like:
The total day is 7-8 hours including transit. Build flexibility into the schedule — captains may adjust based on conditions.
Almost nothing. To be specific:
Pack everything you'll need for the day. There is genuinely no support infrastructure.
Tanjung Luar itself is worth understanding. It's east Lombok's fishing capital, a working Sasak-Bugis community with a daily fish market, a busy harbor, and a slightly hard-edge atmosphere. It's also been a site of controversy due to historical (and sometimes still ongoing) shark fishing — visitors with strong views about marine conservation should know this context.
The boat captains who run snorkel charters to Bumbang are part of a slightly different community — fishermen who have shifted toward tourism work as snorkel sites become more valuable than continued fishing pressure. Supporting the snorkel charter economy is broadly positive for marine conservation in the area.
Be respectful when at the harbor. Dress modestly. Don't photograph the fish market or fishing operations without permission.
Day-trips typically return in early-to-mid afternoon, before the sunset window. If you want to stay later for sunset photography from the islet, ask the captain — most will accommodate for an additional 200-300k IDR but you'll need to ensure the return crossing is in light conditions for safety.
Sunset on Bumbang itself is dramatic — the islet is east-facing toward the Alas Strait, so you get sunset reflected light on the water and the silhouette of east Lombok's mountains in the distance. For most visitors though, a standard daytime trip returning by 3 PM is the practical option.
What is here: small uninhabited islet, surrounding coral reef, small beach landing, your boat captain.
What is not here: any infrastructure, food, water, toilets, shelter, signal, rescue.
Bring: snorkel gear (own preferred), reef shoes, packed lunch, plenty of water, sunscreen, hat, dry bag, cash for charter.
Right for: snorkelers wanting healthy reef and shark sightings; travelers seeking off-the-beaten-path Lombok experiences; couples wanting a private day on a remote islet; anyone interested in east Lombok's fishing culture; budget travelers wanting cheap snorkel day-trips.
Wrong for: visitors who can't swim or snorkel; anyone uncomfortable with simple boat travel and spray; package tourists; party-seekers; visitors with limited time who need to see headline destinations only.
May is a strong month to visit Bumbang Island. Calm crossings, improving viz, low boat prices, and you'll be the only visitors there most days.
Tanjung Luar is east Lombok's main fishing port and the obvious launch point for Bumbang Island day-trips. Negotiate directly with a local boat captain at the harbor — a private day-trip charter for 4-6 people runs 500-800k IDR including fuel, much cheaper than agency bookings from Senggigi or Kuta. Ask specifically for a boat with a basic sun cover (most have one) and bring your own snorkel gear; the rentals on boats are inconsistent quality. The captains know exactly where the reef sharks tend to be and will time your snorkel stops to catch them on the outer reef.
