Hi Narayann,
there are lovely family holiday places withing 3 to 4 hours form bangalore, in good surrondings for easy walking and and also cycling on small country roads without traffic. but renting cycles, ... that is another thing i have not come across yet. youmust take them along yourself.... i think.
maybe at our
native village resort outside hesargahtta they have cycles to rent.
dodballapur and beyond you
have green valley resort, good excursions form there also .
try
Georgia sunhsine. a perfect family place in perfect surroundings for family cycling, totally relaxed and no steep inclines and still good views.
it is off the mallavalli -Kollegal road.only 3 hours form Bangalore. very near the canals to the shimsha hydro power plant. it has got a little pool also.and of course close to kavery river and the falls at shivasamudra.
happy holidays,
georg
