When you head to the boat for your dives, you walk down a path to a little sandy beach. There's a dock there and some stairs to access it.
Be prepared to get wet! When the water is up, it'll get your shorts and shirt wet. Some people like to suit up at the shop but if you're not one of them then make sure you've got your things in dry bag and get your phone out of your pocket!
The water is supposed to be the same temp all year long with very minor changes. Most of the divers I saw wore full suits.
I was comfortable with a 3mm shorty. In the afternoon I'd just have on my hooded lavacore vest (no sleeves).
Definitely bring something to protect you from the sun and wind. Some of the boat rides out are a bit long and chilly.
If you forgot a towel, just ask for one! CMLC supplies them!
There are also lockers! You can leave your stuff here for your dive, or even overnight if you don't need it.
Lots of space here. Plenty of room to chill out. Don't forget to leave a message on the wall if you can find some space!
If you do two dives in the AM you get to have lunch. I got lunch every day. My friend said there was a charge for his lunch (he joined us for two pm dives). I don't care. It was good. And there there was even extra stir-fry beef and vegetables that they offered us! The 3 days I was with CMLC Artha, there was beef, pork belly, and chicken in bento boxes. Yum! They also offer you water, coffee and tea.
Boat snacks were supplied as well as water. And iced tea one day too!
You can take and fill out these slips of paper for your log book. There's a little map of the dive site on some of them too.
