Vrulje Anchorage Guide

Also known as: Uvala Vrulje, Vrulje Bay, Vrulje Cove Kornat

Vrulje is perhaps the most dramatic anchorage in Kornati — a narrow slot between sheer white limestone cliffs that rise 100m+ above the water, carved by geological forces into a cathedral-like space. The word 'vrulje' in Croatian means 'underwater springs', and freshwater seeps can be felt at certain tidal states in the bay head. The bay runs NE–SW and the towering walls create a deeply atmospheric space that looks and sounds like nowhere else in the Adriatic. Anchoring is extremely limited — the cliffs plunge into 20–30m of water with almost no ledge, leaving only a tiny sandy patch at the very head. Most crews anchor bow-out from the entrance shelf with a stern line ashore. A lunchtime visit in calm conditions is unforgettable even if overnight is impractical for most boats. Part of Kornati National Park.

Yes — Croatian eNautička cruising permit required. Kornati National Park daily entry fee per person. Anchoring only at head or entrance — mid-bay rock bottom prohibits anchoring elsewhere.

80m

Recommended Anchor Alarm Radius

80m at the bay head, where anchoring is possible but limited. The dramatic cliffs on both sides restrict any lateral swing. If anchoring in the entrance zone with a stern line, alarm radius can be reduced to 40m as movement is constrained by the line. Do not anchor in mid-bay — the rock bottom gives no purchase.

Bay head — very limited anchoring: 80m recommended — The bay head has limited flat sandy bottom — the cliffs plunge dramatically into deep water most of the way to the head.

Mid-bay — deep and dramatic: 140m recommended — Mid-bay depths of 15–35m are spectacular but not suitable for anchoring — rocky bottom with isolated sand patches, insufficient holding for overnight stay.

Entrance — stern-to or short stop: 70m recommended — A small platform of 4–6m near the N entrance shore allows a few boats to anchor bow-out with a stern line to the cliffs.

Anchoring Zones

Vrulje has 3 distinct anchoring zones, each with different depth, holding, and exposure characteristics. Choose the zone that matches your boat size and the expected overnight conditions.

Zone 1: Bay head — very limited anchoring

  • Depth: 512m
  • Bottom: sand, rock
  • Holding: Fair holding
  • Protected from: N, NE, E, SE, S
  • Exposed to: W, SW, NW
  • Recommended alarm radius: 80m

The bay head has limited flat sandy bottom — the cliffs plunge dramatically into deep water most of the way to the head. Only a tiny sandy patch at the very head offers holding in 5–10m. Space for 2–3 yachts maximum. The holding on the sand patches is fair but the rock substratum below can cause the anchor to skate if not well set. Snorkel to verify. Set with engine power, give at least 4:1 scope on sand.

Zone 2: Mid-bay — deep and dramatic

  • Depth: 1535m
  • Bottom: rock, sand patches
  • Holding: Poor holding
  • Protected from: N, NE, E, S
  • Exposed to: W, SW, NW
  • Recommended alarm radius: 140m

Mid-bay depths of 15–35m are spectacular but not suitable for anchoring — rocky bottom with isolated sand patches, insufficient holding for overnight stay. A lunchtime stop in calm conditions only; lay an anchor on a sand patch if you can locate one. The cliffs rise vertically from the water surface — the acoustic effect is extraordinary.

Zone 3: Entrance — stern-to or short stop

  • Depth: 48m
  • Bottom: sand, gravel
  • Holding: Fair holding
  • Protected from: N, E, SE, S
  • Exposed to: W, SW, NW
  • Recommended alarm radius: 70m

A small platform of 4–6m near the N entrance shore allows a few boats to anchor bow-out with a stern line to the cliffs. The holding is fair on gravel/sand. This is a more workable overnight option than the bay head for boats with long lines. The stern line keeps the boat stable against the NW Mistral.

Setting Your Anchor

The bottom at Vrulje is primarily sand and rock with variable holding that requires extra attention. Use the following approach:

  1. Approach slowly and check your depth sounder on the way in. At 512m, deploy at minimum 7:1 scope (84m chain at 12m depth).
  2. Drop into the wind or current and pay out chain steadily as the boat drifts back — do not allow chain to pile on the anchor.
  3. Set firmly in reverse. Apply moderate throttle astern for 30–60 seconds. The chain should tighten without the boat moving backwards.
  4. Snorkel to verify. Given the fair holding here, it is strongly recommended to snorkel down and visually confirm the anchor is buried in sand, not resting on Posidonia or rock.

Recommended anchor types for this bottom: Rocna, Mantus, Spade. See our guide to anchor types by bottom for detailed comparisons.

Overnight Anchoring & Anchor Alarm

Overnight stays at Vrulje are feasible but require monitoring. The anchorage is exposed to W and SW and NW winds.

Set your GPS anchor alarm to 80m radius before going below for the night.80m at the bay head, where anchoring is possible but limited. The dramatic cliffs on both sides restrict any lateral swing. If anchoring in the entrance zone with a stern line, alarm radius can be reduced to 40m as movement is constrained by the line. Do not anchor in mid-bay — the rock bottom gives no purchase.

Best in May–June and September when Mistral is lighter and predictable. July–August works for daytime visits but the entrance can become busy by noon; overnight is feasible in calm settled spells only. Avoid entirely in W, SW, or NW winds above F3 — the entrance slot amplifies any westerly swell.

Navigation Hazards

  • Very deep water with rocky bottom — most of the bay is unanchorable; lunchtime stop in calm only for mid-bay visit
  • NW Mistral channels through the entrance slot and creates an uncomfortable swell in the outer section; depart or move to bay head if wind increases
  • Stern lines to the cliff face are required for most viable overnight positions — ensure lines are well secured on reliable rock cleats or natural features
  • Rock fall from the cliff faces is a theoretical risk in heavy rain or seismic activity; keep clear of cliff edges
  • Very limited swinging room at the bay head — only 2–3 boats maximum; do not attempt to anchor here if already occupied
  • Jugo (SE) makes the entrance approach unpleasant and sends swell in from the W side — avoid in SE conditions

Rules & Regulations

  • Kornati NP entry permit: Required — Croatian eNautička cruising permit required. Kornati National Park daily entry fee per person. Anchoring only at head or entrance — mid-bay rock bottom prohibits anchoring elsewhere.
  • Anchoring fee: Free to anchor; park entry fee per person per day
  • Maximum stay: 1 days
  • Restrictions: Anchoring on rocky mid-bay bottom not recommended — anchor only at bay head (sand patch) or entrance shelf. No fires or BBQ. No motorised water sports in the bay. The acoustic environment is extraordinary — please respect other visitors.
  • Croatian eNautička (MMPI) permit also required — obtain before entering Croatian waters.

Skipper's Tips

  1. Visit at midday when the sun is overhead and lights up the turquoise water inside the cliffs — the colour and reflection effects are extraordinary and make for exceptional photography
  2. The best overnight technique: anchor on the sand patch at the bay head in 6–8m and run a long stern line to the cliff (150m+ of extra line useful) — keeps the boat stable in Mistral
  3. Underwater freshwater springs can be felt by swimming near the bay head — look for the shimmer of fresh water meeting salt
  4. Enter slowly and watch the echo-sounder carefully — the bottom profile drops sharply from 5m to 20m within a short distance
  5. The walk up the cliff path (N side) to the ridge gives a spectacular aerial view back down into the bay — allow 45 minutes return

A note on this guide: The data in this guide has been researched from multiple sailing sources and is provided in good faith. Anchorage conditions — including depth, holding, national park fees, and local regulations — can change. Before visiting, always check current weather forecasts, NAVTEX and VHF weather bulletins, and consult your up-to-date HHI charts. Use a GPS anchor alarm and never rely solely on a guide for navigational decisions.

Sleep peacefully at Vrulje

Safety Anchor Alarm monitors your GPS position continuously through the night and sounds a loud alarm the moment your boat drifts outside your set radius — so you can relax and enjoy the Kornati without worrying about bura overnight.
