just be nice, give people benefit of doubt.
we were all new once.
TS -
1) if you afraid you don't know the way, it is not hard, one straight road down. you can use eikin's map and walk from punggol mrt, i used to do that when i had a lot of free time. if you can't find the link, sound out here.
2) if you are horrible at using maps, just take bus 82 from front of punggol mrt, or wherever is convenient for you. when the bus start doing a bus style whatever-point turn, that is when you get down, at the end of the road at a place that looks like where civilisation ends in singapore. the beach with all the rocks that you usually see is to the left. note that you might need to climb down drain, i have a phobia of heights but i handle it fine, so you can tell how relatively safe it is. just test the rocks you have to place your feet on first, before planting them on and putting your weight on them.
3) if you still scared, wait for someone to organise outing. sooner or later will have.
sorry that i can't offer to organise outing, i always believe that landscape outings are optimally a 2 person routine, at most 3. i usually shoot with riotvan here these days, so i guess there is no room for anyone else unless i know them well.
