There's not much for the non-diver at Thonga Beach resort, unless you like lying in the sun doing nothing. There is a 'spa' but i can't comment because they aren't my cup of tea. A trip to the lake is good at sundown to see the crocs & hippos. We chose this time of year specifically to see turtles laying eggs which you do as an evening drive up the beach. they will also take you on a guided walk into the dunes to see the smaller life.
AND the eating, i promise you you will not starve!
i was impressed by the 'instructor' (we didn't get any instruction from him and given our experience and his we didn't expect any). He was a good buddy, interested in the life and after every dive he was looking at the books because he saw something he didn't know and wanted to learn. He's diving for a living & still enthusiastic.
The diving is from an 8m RIB which is launched off the beach so you have to help with that, given 2 guys have just carried your stuff down for you it's the least you can do & not difficult. The boat ride to the reefs is exciting, but i won't spoil it for you.
the diving itself is no more than 23m which given the swell of the ocean makes photography challenging as there is a swell. The reefs are exclusive to Thonga beach (as are the more northerly to Rocktail Bay) and the boat takes 8 people max, day 1 it was us with the instructor after that another guy joined us, that's about as crowded as i like it
vis was between 15 & 20m, water temp 20degrees c. life in abundance, no wrecks. corals, fish forever, hydroids, eels, sharks, the day i didn't take the camera turtles, sharks, sponges, lovely little worms living in the corals, echinoderms.
The resort is about 1.5hours over 4wheel drive only roads from the nearest town, the resort meet you & drive you in. We made the mistake of flying to Durban & getting a transfer to the meeting point, with hindsight i would fly to Richard's Bay as it's a couple of hours closer.
Are you doing anything else in KZN whilst you are there, we had a safari at Hulhulwe a couple of years ago & enjoyed it.
i've gone on a bit now & i'm not sure this is the correct forum, if you want to pm me with any questions please do.
