For the Water Freaks Thane Creek, though a good place to seek a peace of mind and the kidney, isn't exactly a good place for couples. Other water bodies would include some 23 oddlakes spread all over the city. One of the most popular places is Talopali where one (read as two) could sit on the benches if one can stand the standing Romeos or may be row around in the lake in boats or water scooters. It also offers an array of roadside eating options, from Bhel to ice cream its all laid out there or you can enjoy a quick snack at the nearby Restaurants. Talaopali is frequented by people of all age.
Upvan Lake is more popular with thecouples that do not have the permit from their parents or are below the requisite age to dare ask. You would see college couples bunking classes and having a tete-a-tete (read as altercation). One could either sit inside the park on one of the benches ( if one manages to find an unoccupied one), or the katta around the lake. You would have to make up with your partner before 8 p.m. after which some torch bearing policemen would be using persuasive methods to make you leave.
For the Vechile Freaks Some of the options would be a drive on the GhodbunderRoad right upto Ahmedabad Highway or the MIDCRoad which runs parallel to the Thane - Belapur Road or up into the Yeour Hills which offers not only a pollution free zone but also a touch of wilderness.
Thanks to the Commissioner, one can have a speed test even on the streets if one doesn't have the fear of being seen by the Mama (Traffic Cop).
For the Nature Lovers Yeour hills is definitely recommended for those with affinity for nature. A visit to the Swami's Math is a must for those seeking peace. If you are lucky, you might get to see a few wild animals, and if you are not maybe a few wild human beings. But a visit after dark has a high probability of attracting both.
Tikujiniwadi is more domesticated wilderness. For a nominal sum, you could spend the entire day including good feast at the in-house restaurant and an execellent siesta on the khat or the satranji (for which you pay of course) under the trees.
