Any knowledge about boat for hire from Bang Sarey to Ko Krahm island for day trip ?

thanks

There are a number of boats that can be hired for fishing trips that operate out of Bang Saray, most of them off jetty No 2. As you go down the hill from the temple, the main jetty is in front of you, take the soi on the left and within 50 metres look for a narrow entrance on the right. Walk along the quay and you'll see some of the boats if they're not out on trips. Expect to pay 8000 baht or more for the day. I don't know of smaller longtail type of trips from there.

Ko Khram is protected by the navy, I've seen people on some of the beaches there but I don't think anything else is allowed.
