There is no wheelchair access to the entrance of the Underground. Visitors will need to climb 48 stairs (3 sets of 16 with benches to rest after each set) to reach the tunnel entrance. There are no stairs at the tunnel exit – instead there is a downhill gravel slope. The ground is uneven in places inside the Underground tunnel.
There are instances of loud noises but warnings will be given. The underground is cool year round and good footwear is recommended.
