Ikura is a vertical cave rather than a horizontal one. The route runs 1,200 metres into the limestone with 90 metres of elevation gain, so instead of strolling along a level floor you climb stairs and ramps through chambers stacked above one another, past named formations and an underground waterfall that drops the full height of the system near the end.

The entrance is at the foot of a 240-metre limestone cliff on the Takahashi river, which is a piece of scenery in its own right, and the gorge road below it is one of the more dramatic drives in the prefecture. The cave holds around 15 degrees all year.

インサイダーガイド

**Ninety metres of climb, and it is stairs.** This is the fact that catches people out. Not suitable for anyone who cannot manage a long flight of steps, and not passable with a pushchair. **Fifteen degrees all year.** Bring a layer in summer; in winter it is warmer inside than out. **The floor is wet everywhere.** Grippy shoes matter more here than in most show caves because of the gradient. **The cliff outside is worth stopping for.** A 240-metre limestone face over the Takahashi river, and the gorge road below is a good drive in its own right. **Makido is nearby.** The other Niimi cave is horizontal, half the length, and completely different in character — a wide chamber with a still pool. Doing both in a day is the standard local circuit.
