We have always booked our trips through Carole and Tayfun.
Have been on the jeep safari a couple of years ago - That was good, wet fun with a lovely trout meal at the trout farm. Our teenage daughters loved it, and some of the little villages we went through were delightful, with all the children coming out to wave and shout a greeting (plus a good soaking with their water hoses!). Only downside were the children thrusting flowers onto you at some of the stops in exchange for money. I took loads of sweets with me but they didn't want those!
The Islands cruises are very good, both the 12 Islands and the 3 Islands (which starts at mid-day). The food is good (usual choice of fish, chicken or meatballs) and the staff very knowledgeable. The stops vary each time you go, but the whole experience is one of relaxation and fun.
We've also been on the Tlos and Saklikent trip with C&T a few times; again very enjoyable, with excellent informative guides and good food.
Our favourite trip is the Sunset Cruise, specially if you're feeling in a romantic mood! The trip leaves around 6pm from Fethiye, arriving back at midnight. The food (steak or chicken plus pasta, salad etc) is very good. There is a British singer (very average, but enjoyable) followed by a disco, so lots of dancing. The last hour is filled with slow, smoochy music which is gorgeous as you arrive back into Fethiye under the stars. Ahhhhhhh ......
Have also been on the Turkish bath trip a few times wit C&T. Again, very good value, includes pick up and drop off. They take you by private pick up to Hisaronu and the guy at the baths is very funny (though slightly pushy) when he sells you the "extras" (facials, massage etc). Again, if the weather isn't too good, this is a really lovely afternoon out; very relaxing.
Is that enough information Keith? And Carole and Tayfun - if you're reading this, hope I get discount on my next booking after such good reviews for your company!!!
One other thing, if you book online before you go on holiday, you make a substantial saving. You may even qualify for a very cheap trip to Gocek, Fethiye market or the Turkish Bath (think it's £2 each if you book 3 or more trips - easily done in the summer!)
The boats are not over-packed and the staff knowledge of the area is very good.
