We set off on our return journey, but first to the zoo. Turn into the Regents canal from Little Venice and cruise past more pretty house boats and narrow boats. A deep cutting then goes through the short Maida Hill tunnel. Past the grand houses of St. Johns Wood and suddenly we see the Snowdon Aviary. The birds inside were less grand than the structure. The zoo gardens along the bank of the canal look very drab and in need of a makeover. Not many animals to be seen. Turned at Primrose Hill to see it all again. The canal is cut quite deep and we did not see any of Regents Park.
