I've done a few walks in Singapore. The McRitchie and Mandai routes are interesting... dense jungle but safe. check this out at www.whereizzit.sg

You'll be surprised that there are lots of places you can go hiking in Singapore. MacRitchie Reservoir - well marked trails, Bukit Timah - well marked jungle trails, Chestnut Ave to Upper Pierce Reservoir - jungle trekking etc. Check this: http://www.whereizzit.sg/jungle-trails
