SAPUTARA

a rather negelected hill station 1 km from the gujarat-maharashtra border on the gujarat side.
plenty of hill walks.
not to miss the one to sunset/sunrise point and onwards to the clifftop NE of the point.

262km from bombay by the shortest road. the straightforward route is to nashik along NH3 and onwards but a stunning ride is :
mumbai-khodala-tryambakeshwar-nashik-saputara-
nashik-igatpuri-bhandardhara-rajuri-kotul-brahmanwada-
otar-malshej ghat-kalyan-mumbai (700km)
this is especially fantastic in the monsoons.. you'll o.d. on the green. also expect much mist on the ghats. and if its raining it'll be a trip and a half.

bewarned : saputara is full of dirty, noisy g*jjus on weekends (i know i'm a bigot, so sue me).

very cheap accomodation at the dormitory at Toran (GTDC hotel) - Rs. 50/- a head on weekdays, Rs.100/- on weekends. in the dorm section of the hotel there are 10 large rooms, some with 6 some with 15 beds. so if there is not much of a crowd you can sweettalk the receptionist into giving you one room to you and your group and put up any other guests in the other rooms. The only drawback being you'll have to share the loo. which is none to clean.

quite a few hotels otherwise but i didn't do any research.

another attraction in saputara is a cable car ride from one hilltop to another. (i missed it but it promised to be good).
