Spend your first day in Mumbai making a difference in the lives of street children. Sneha Sadan is a non-profit organization that provides food, shelter, education, and medical assistance to abandoned and destitute children living on the streets. Spend some time playing educational games, drawing, and singing with the children. You can also volunteer to teach them English, help with administrative work, or assist their staff in other ways. The organization usually provides lunch to volunteers, and you can donate money to the cause if interested.
Make an impact on the environment by spending a day cleaning up the beach at Versova. Versova beach is one of the most polluted beaches in Mumbai, and volunteers are always appreciated to help clean up the trash and debris on the shore. The cleanup activities usually take place in the morning, and you can reach the beach through public transportation or by hiring a taxi. The work can be a bit strenuous but is definitely rewarding.
If you have an extra day, you can visit the Gateway of India, one of the most famous landmarks in Mumbai. Also, Mumbai is known for its street food, and you can try local delicacies like vada pav, pav bhaji, and bhel puri. However, make sure to eat at hygienic and recommended places. If you have less time, you can visit other non-profit organizations like Apnalaya or Akanksha Foundation for volunteering activities.
