It was bucketing down, so we decided to visit the cave to escape the rain. The entrance to the cave is about 450m from the free parking place. As it was raining we were a bit cheeky and drove as far as we could, but still it was a bit of schlep to the entrance, it is an uphill path and when it is raining it is also quite muddy.
The guide was a bit offish but delivered the commentary in croat and english for the small party of people that gathered for this tour. The tour took about 45 minutes and was ok. The cave isn't the most spectacular place - a hole underground with a few bats and stalactites, etc.
