Grottoes Park Escape

It was a long week for you at your work place. The busy schedule throughout the week and lots of work has drained you out. You need a break and so you have gone to cave park to spend the weekend there. You did like the place for a while and started feeling relaxed but these good things did not go on for too long. The huge old stone gate got automatically locked behind you and it is impossible for anyone to open it up with physical strength. However, you are very sure that there will be another to unlock the gate and you must find it.
