Changi Beach
Right next to Changi Airport, you can watch and hear the neverending parade of airplanes from here. Usually full of local picnickers, but not too many sunbathers or swimmers around. If you walk along the beach to the southeast, you will eventually pass by Bedok Jetty and arrive at East Coast Park.
Pulau Ubin
Singapore's flashback to yesteryear, a little island off the northern coast where people still live in fishing villages on stilts. The island is covered in biking trails and is an excellent spot for a little steamy jungle offroading; bike rentals go for as low as $2 a day, and the 45-hectare Ketam Mountain Bike Park has a good 10-km trail. At the east end of the island, reachable by bike or shuttle bus from the jetty, are the Chek Jawa Wetlands, with a mangrove boardwalk, an observation tower and a visitor centre. Access to the island requires a bit of effort though: take the MRT to Tanah Merah, then ride bus 2 to the bus terminal in Changi Village alternatively MRT to Simei, then bus 9 that passes Changi Village by, find the jetty and hop on a bumboat $2.50 each way for the 10-minute ride to the island.
The best bits of eastern Singapore are its beaches. In addition to the ones below, try Pasir Ris or Punggol to really get off the tourist trail. Camping and barbeque permits for all parks are available at AXS (http://www.axs.com.sg/php...).
