How to spend $101 (you big spender, you) in a day   by Serene Lim     This city on the southern tip of Sri Lanka harks back to Dutch colonial times with a magnificent 16th century fort surrounding its perimeters. With the crashing waves of the ocean on one side of the walled city and a lively bustle of daily activity on the other, exotic Galle (pronounced "gaul") is a magnet for free-spirited culture vultures and fervent beach lovers longing to ramp up their indie traveller cred. Serene Lim   Cycling tour of Galle City: S$46.24   As long as you're adequately fit and still equipped with your childhood cycling skills, you can ride a bike. Biking is definitely one of the best ways to see the city, peddling through the narrow historical alleys and out into the outlying areas. Sri Lanka Day Tours (www.srilankadaytours.com/galle_Galle_City.php) organises these picturesque cycling trips that will take you from the fort all the way to the beaches of Unawatuna where you can cool down with a dip. The US$37 fee includes a guide, rental of mountain bikes and all taxes.       Treatment at Jetwing Lighthouse Spa: S$53.50   Located in one of the prettiest hotels in Galle, Jetwing (www.jetwinghotels.com/jetwinglighthouse) overlooks the Indian Ocean and is an indulgence worth every cent to soothe your dying muscles after your cycling stint. Choose the 60-minute aromatherapy massage that won't bust your budget at RS4,700.       Sunset from Fort Galle: S$0   Now rejuvenated, make your way back to the nearby Galle Fort. Walk along the scenic ramparts, which have withstood the devastation of the Boxing Day tsunami in 2004, and take in the gorgeous sunset over this beautiful city and capture this special moment in time.       Total: S$99.74       Prices and conversion rates accurate as of press time.       This article was featured in Today 19, 2011. http://www.todayonline.com/Travel/EDC110519-0000226/Travel-101-,,,-Galle
