After reviewing visiting Turtle Island near Tanjung Benoa (and reading all the negative reviews) we decided to visit the Conservation centre in Serangan.
When trying to write this review and searching for the Turtle Conservation centre, Serangan on Trip Advisor- there were several reviews but they seem to be reviewing the Tanjung Benoa version and are all very negative. Finally I found this review but there's only been 1 review.
I'd give the centre 3.5 stars (but can't give a half star with the mouse). It is very basic but I found it quite interesting and how often do you get so close to turtles and pick them up - even baby ones? When we arrived (a sunday) there were school children there learning about the plight of the turtles. It's great that they are teaching their children this.
The centre isn't very large. There is a large section with young turtles of various ages (separated from each other) who when healthy will be released back into the ocean. A staff member will come over and give you information about them and allow you to handle them (gently). Our 14mth baby was fascinated by the turtles (but was scared when a small 3 mth turtle was flapping its fins close to her).
There is a large pool where the larger turtles live and swim until they can also be released. Some of these turtles are huge. There is also a section where fertilised eggs are buried (fenced off) for hatching. There's also a small tortoise area as well.
The centre doesn't charge and just asks for donations - we gave a generous donation.
If you want to see turtles close up and learn more about them from the volunteer staff, I'd recommend visiting. But don't expect flash facilities like you might see at a marine park back home.
