cocasana:Thanks Gabyne.
All the livaboards I found were full, dates didn't work and/or they had at least 10 days cruise, while I can stop there only 7 days. At the end I found the Kri Eco Resort, they had place, so I've booked there. Apparently Kri island is one of the most interesting dive spots of Raja Ampat!
Manusuar and Kri is only a very small part of Raja Empat, to do it properly and get a good feel for the coral diversity and fish life diversity you really need to a 10 day trip or more. Kri has a couple of outstanding Dives those being Kri point and Sardine but both need to be dive at the right times (currents) to show just how spectacular they are.
With out a lot of additional cost (besides travelling in a small boat that the resort has - not overly comfortable and sleep in the open air) you will ot get to one of the best dives in Raja for corals and fish life Batu Burung aka Melissas Garden in the northern Fam Group. Others being the big Botton aka loloh islands which has one of the best swims throughs I have seen (goes right through the island and have seen tawny nurse sharks and large Queensland groups and Giant trevallys in the cavern)
Whilst down in the southern area of Raja Empat Missol there is the kaleidoscope (a wall in Jef Pele that is just a mass of beautiful colours) Fiabacet a small rock with a great drop off and schooling barracuda and great soft corals Boo Island similar to Batu Burung but easier to dive as has less current.
7 days really sells this area short as there is a lot of distance to cover to see the majoirty and really impossible to properly in just 7 days.
So if you have the opportunity go with the SMY Ondina
