Start your day at the iconic Gateway of India, a monument built to commemorate the visit of King George V and Queen Mary to Mumbai. Marvel at its unique blend of Hindu and Muslim architecture and gaze out at the Arabian Sea. Take a boat ride to Elephanta Caves for a mystical experience (closed on Mondays).
After an action-packed morning, head to the famous Leopold Cafe & Bar, open since 1871, for some refreshing beer and delicious Continental cuisine. Sit back and soak in the old-world charm of this iconic cafe.
Next, head to Chhatrapati Shivaji Terminus, formerly known as Victoria Terminus, a UNESCO World Heritage Site and one of Mumbai's busiest railway stations. Marvel at its Victorian Gothic architecture and witness the bustling life of Mumbaikars. Do not miss the adjoining Heritage Gallery.
As the day comes to an end, unwind at the scenic Marine Drive, a 3-km long promenade along the Arabian Sea. Soak in the sunset views, grab some street food and watch the city come to life.
If you have more time, you can visit the iconic Taj Mahal Palace hotel near Gateway of India or explore the art galleries and boutiques in Colaba. For history buffs, the Prince of Wales Museum and Jehangir Art Gallery are worth a visit. If you have less time, skip the boat ride to Elephanta Caves and opt for a local lunch at Khyber or Baghdadi nearby.
