(2) Take the path on the left. Follow the gently sloping path; at the end of the path, turn right at the hairpin bend. Continue along the path, which runs almost parallel to the one you have just taken, and cross a small, barely visible bridge (see photo); the stream it crosses runs dry in dry weather.
