In car its about 50 minutes drive, but there is an excursion bus which takes around one hour 10/20 mins.on a Monday, Wednesday and Friday, 09.00 to 18.00 The excursion gives you a whole day there and is quite economical, but if you have car for day you can end up at Aqualand to chill out for a few hours; after three oclock there is a reduced rate.
There is also the Hydropolis water park in Acharavi about 3 kms away which has a free pick up service from Roda. Smaller but good value and good family entertainment. Our kids arent tired of it yet in some 4 years of operation!
Happy Holidays~!
