Start your honeymoon with a visit to the Gateway of India, an iconic monument built-in 1924 to commemorate the visit of King George V and Queen Mary. Take a boat ride to the Elephanta Caves, a UNESCO World Heritage site consisting of rock-cut temples dedicated to Lord Shiva. Witness the historical architecture and carvings in the caves, and enjoy the stunning view of the Arabian Sea.
On the second day, head to the Bandstand Promenade for a romantic morning stroll with your loved one. Enjoy the picturesque view of the Worli Sea Link, and catch a glimpse of famous Bollywood actor Shahrukh Khan's luxurious house, "Mannat." Then, visit the Siddhivinayak Temple, a popular Hindu temple dedicated to Lord Ganesha. Embrace the spirituality and divine aura of the temple.
If you have more time, consider adding a visit to the Chhatrapati Shivaji Maharaj Vastu Sangrahalaya Museum to learn about the city's rich history. For a unique dining experience, head to the Dome, a rooftop lounge offering a magnificent view of the city along with delectable cuisine. If you have less time, prioritize the Gateway of India and the Siddhivinayak Temple, as they are must-visit destinations in Mumbai.
