Getting to Ubin requires you to get to Changi
Point, on the east end of the island not far from the airport. You
can take the number 2 bus from the Bedok MRT station, although it does
take about 30-40 minutes to get there. When you arrive at Changi
Point, have a light breakfast at the hawker centre. May I suggest
roti prata? Yummy. After eating your breakfast, walk down to
the boat dock and hire a bumboat driver to take you over to Ubin.
Here's the deal: a bumboat costs $15 to hire, one way. If you are
not in a hurry, you can wait until the boat has 12 people and then you
will each pay $1.50 to hire the boat. If you are in a hurry (and
who isn't, at this point), just pay the guy the full amount and he'll
take you and your friends over without a full boat.
There is a good reason to be in a hurry, by the
way. If you don't reach Ubin early, you will not get a good
bike. You can, by the way, bring your own bike over to Ubin, but
if you don't drive, getting your bike just to Changi Point is very
inconvenient. The bikes at Ubin aren't the highest quality, but
neither are they likely to fall apart underneath you. The newer
bikes are full suspension, which makes it easier on your backside after
riding a few hours. But you won't get these unless you are early,
thus the reason to get a boat as soon as you can.
