Rangko Cave (Gua Rangko)
A turquoise cave pool near Labuan Bajo that glows electric blue at midday — the perfect land-day pairing before or after your Komodo boat trip.
Quick answer: Rangko Cave is the half day that fits between your boat days. Komodo boats dock in Labuan Bajo by 15:00–17:00 and most travelers keep a buffer day before flying out — Rangko is the best possible use of it: a 45–60 minute drive to Rangko fishing village, a 15–30 minute local boat, and a saltwater cave pool that glows electric blue in the midday light. It sits outside Komodo National Park, so there are no park fees, no quota and no ranger to book — the whole outing for two people sharing runs roughly IDR 350,000–500,000 (≈ $22–32) each.
Why the Between-Boat-Days Slot Works
The itinerary logic writes itself. Open trips end at the harbor mid-afternoon; flights out are best booked for the following day. That leaves one land day — and Rangko’s light window sits exactly in its middle. The pattern our desk books again and again: morning at leisure, depart town at 11:00, swim the cave in the 12:30–14:30 glow, back for a waterfront dinner. Travelers assembling a fuller land day pair it with Batu Cermin cave or Melo village on the same loop. If you are still building the rest of the itinerary around it, our Labuan Bajo tour packages page maps the combinations, and Komodo Luxury’s own Rangko Cave guide covers the premium private-boat variant of the same outing.
What It Costs, Item by Item
No tickets are sold online and none need to be — everything is paid locally, in cash, in rupiah:
Two people sharing boat and car spend roughly IDR 350,000–500,000 each for the whole outing — among the best-value half days anywhere in Flores.
Light Window and Tides
The famous glow happens when direct sun drops through the cave mouth onto the water: roughly 12:00–15:00 WITA, peaking between 12:30 and 14:30. Arrive at 10:00 and you swim a beautiful but ordinary dark pool; arrive at 13:00 and the water turns luminous turquoise over white sand. Plan the drive to put you at the village jetty by 11:30. Tides matter less than sun — the pool is sea-connected and swimmable at normal tides year-round, and the light window, not the tide table, should set your schedule.
Getting There, Step by Step
Swim Rules and Village Respect
The pool is about four meters deep, saltwater and brilliantly clear — swimming is the whole point. A few rules keep it that way: no jumping from the rocks (depth is uneven and help is an hour away), never touch or hang from the stalactites, and carry your rubbish out — Rangko is a Bugis fishing settlement and the cave sits on community land, kept clean without any park funding. The entrance fee and boat hire are village income; a friendly hello and fair dealing go further than hard bargaining ever will. Seniors manage the visit comfortably at an easy pace.

Frequently Asked Questions
Can I fit Rangko Cave between Komodo boat days?
Yes — that is exactly the slot it was made for. Komodo boats dock in Labuan Bajo between 15:00 and 17:00, and most travelers keep a buffer day before flying out. Rangko fills that day perfectly: leave town at 11:00, swim the cave in its 12:30–14:30 light window, and be back for a waterfront dinner.
How much does Rangko Cave cost item by item?
Village entrance is about IDR 20,000 (≈ $1.30) per person, the local return boat IDR 200,000–300,000 (≈ $13–19) per boat — not per person — and a car with driver from Labuan Bajo IDR 400,000–600,000 (≈ $26–39) for the half day. There are no Komodo National Park fees, because Rangko sits outside the park. Two people sharing boat and car spend roughly IDR 350,000–500,000 each.
What time is the light best at Rangko Cave?
The pool glows when direct sun drops through the cave mouth, roughly 12:00–15:00 WITA, peaking 12:30–14:30. Aim to be at the village jetty by 11:30. Tides matter less than sun — the pool is sea-connected and swimmable at normal tides year-round.
Is Rangko Cave inside Komodo National Park?
No. It sits on the Flores mainland in Boleng district, about 15 km northeast of Labuan Bajo. That means no park entry fees, no SiOra quota booking and no ranger requirement — which is why it pairs so well with the park days on either side of it.
How long does the Rangko Cave outing take?
Count 45–60 minutes by car to Rangko village, 15–30 minutes by local boat, a short rocky walk, and 45–90 minutes swimming and photographing at the pool. Door to door it is a comfortable half day from Labuan Bajo — morning at leisure, cave at midday, town by late afternoon.
