Raya Yai is an excellent place for scuba diving all around the
year. High season is from October to March but I would recommend
the summertime as well. Also Raya Noi is known from its healthy
reefs and clear waters. Although you can dive here during daytrips
from Phuket, I would recommend staying for a longer time in one of
the hotels on the island.
There are two dive-centers on Raya Yai. Raya Divers is a 5-star dive center
with office near Ban Raya Hotel. There will be soon another office
at Ao Batok (near hotel Racha). Racha Seamaster Divers is at
hotel Racha.
Diving can be done here from the shore or from a longtail
boat.
You need to dive to 20 meters depth during this multicache. Basic
certification is not enough. If that’s a problem you can
improve your skills with diving-instructors. I recommend using
experienced divemasters help anyway to complete these dives. These
two divesites should be available most of the time.
Dive 1, Siam bay (around start coordinates)
How many concrete elephants are sunken into approximately 20 meters
depth? That is A.
Dive 2, Homerun reef
(See the waypoint for inaccurate coordinates) There is a small
wreck lying on the sand bottom near the homerun reef at
approximately 20 meters. How many windows are at the cabin of the
wreck? That is B. Now look the final coordinate from the table
below.
Try satellite view, since the map is poor.
SCUBA DIVING WITHOUT PROPER TRAINING AND EQUIPMENT IS NOT
SAFE, CONSULT DIVE CENTER!
Be prepared that this multi can take a lot of time to solve!
Weather, tide etc. can make it sometimes impossible to dive to
these two destinations.
