the park's green buses. The park is home to an estimated 25 lions and lionesses, of which only 2 can be safely seen at close range from the caged buses. The remaining 23 have been relocated or placed in fenced areas far away from the roads used by the green buses. During visiting hours, some of the resident lions are let out into the enclosure and can be viewed from the safety of the bus. There are 4 tigers that are kept semi-confined in a fenced area that is toured by the buses. A high and long protective fencing surrounds the area. This is done so that all visitors can safely view lions and tigers in their natural habitat. Here the visitors are caged in the bus so the big cats can roam like in the wild. Two other tigers roam in a much larger area. There are many claims that these tigers and lions are tranquilized in the interests of tourism. Walking trails There are a number of public walking trails in the national park. The popular Ashok Van trail winds through thick forest to a dense cluster of Ashoka trees that are a welcome halfway resting spot. The return journey is usually via the Gaumukh trail that leads to an open volcanic rock face and ends at the Kanheri caves. A more challenging route is called the 'View Point' trail and leads to the highest point in Mumbai, which affords a panoramic view of the city and its three lakes – Tulsi Lake, Vihar Lake and Powai Lake. New jungle trails at Sanjay Gandhi National Park allow visitors to see the more unexplored parts of the park for a nominal fee. They are the Shilonda Trail, the Malad Trail, and the Yeoor Trail. The Nagla Forest Block Trail is a famous trail which ends in the mangroves of the Vasai Creek, and is home to many bird species. Local conservation NGOs such as the Bombay Natural History Society (BNHS) and World Wildlife Fund for Nature-India (WWF-India) bring groups of urban residents from Mumbai and elsewhere, sometimes in collaboration with other organisations, for regular guided nature education walks in the nature trails of Sanjay Gandhi National Park and organise special trips when the rare karvi (Strobilanthes callosa) flowers are in full bloom which only happens once every eight years.
