Reviews Summary
Visitors find the WWII Tunnel St. Anthony Channel a freely accessible and historically interesting site, often visited as a detour to St. Nicholas Fortress.

The unique 'Hitler's Eye' nickname and wartime engineering are highlights, though some note potential slipperiness inside.
"I definitely recommend a visit, it's a freely accessible and interesting place that was built by the Germans during the war as a military tunnel. It's only about 250 metres long, but I wouldn't go in it. Obviously, judging by many photos here, a lot of people have done that. :-) I am a chicken.
It's just a little detour on the trail to St. Nicholas Fortress."

"Definitely worth the walk. Cool swimming spot with concrete pad to lay on. Interesting little cave church. We walked all the way through the tunnel. The hike from the decommissioned military base was easy."

"Really cool, there’s a little spot to lie down, we hiked there and happened to get at the same time as a guided tour and the tour guide was cursing people who parked here small boats, he disturbed everyone’s peace (not cool bro), apart from that, absolute gem"

The Strategic Importance of the Tunnel
This engineering feat highlights the advanced military planning of the era. The tunnel's construction was designed to shield vessels from both aerial bombardment and naval attacks, making it a vital component of the German naval operations in the Adriatic. Its existence underscores the historical significance of Šibenik as a strategic port during the war.
Today, the tunnel stands as a tangible reminder of this history. While its military function is long past, it offers visitors a unique glimpse into wartime engineering and the strategic landscape of the Adriatic during WWII. The sheer scale of the construction is impressive, even to modern visitors.

Beyond the tunnel itself, a short climb above it can lead to a surprising discovery: a medieval altar. This adds another layer of historical interest to the site, blending WWII history with older heritage. The entire area provides a mix of history, natural beauty, and recreational opportunities.
