I will start with the usual “we’ve been to many exclusive places around the world” routine...and this really is very true in our case. We have an enormous amount of comparison points. Aman Resorts would probably be a good benchmark with which to compare places such as Fregate, and we have been to most of the Amans.
Fregate is undoubtedly a photographically beautiful island. The the initial arrival is quite a “wow” in that respect, but things sort of disappoint thereafter. The wildlife (we loved it, but for the occasional few a put-off apparently, but you really shouldn’t be in the Seychelles if you are not into birds or centipedes) is very interesting and the conservation effort is clearly to be applauded...although we wondered if really the island was “conservation first, clients second” at times. As of October 2019, the villas and general facilities are dated...certainly for the money one is paying. The beach bar (apparently) isn’t “shabby chic”...it’s just shabby...there’s nobody there ..you have to call someone to come down, eventually. The main restaurant and common areas feel aesthetically very unimaginative. I can’t think of any other of the facilities I would describe as “wow”...the spa area is ok perhaps. Generally they probably need a more inspirational architect or need to commit proper money for a more comprehensive update, not incremental “catch-up/patch up” changes. I won’t go on to list things, but I noticed quite a few things where I felt a good architect with some imagination and attention to micro details may have improved on things. The food is ok but hardly knockout for such an expensive place. The service is well-meaning enough, but quite slow at times, Seychelles-style. All in all, just disappointing for the (very large) amount of money.
The one thing I really need to highlight though, and something that I’m truly bemused does not appear in many other reviews, is the fact that the very photogenic beaches are only useful for just that ...nice photographs...because you can forget enjoying going in the water...and with kids they are 100% a non-starter. Most they tell you to simply not go in (and you wouldn’t, not even strong swimmers), and the two bits they highlight as “swimming beaches” simply are not ...a somewhat scruffy bit of sand called “Marina beach” is simply a foot slicing exercise to get into the water across the broken coral for subsequently not a particularly amazing swimming experience, and the small section down in front of the main restaurant with its nasty shore break would knock most kids (and some adults) off their feet and churn then around in the sand in a nanosecond. There’s plenty of random rocks around under the water to slam into if you get anything wrong. What is disappointing is that via my agent I very specifically asked about swimming possibilities for both adults and children, and was specific about the time of year we were visiting, and the reply was “yes” and the old “the beaches change with the seasons so there’s always nice swimming somewhere”. Rest assured the denial will come, but I really don’t believe it. A manager at another high end place in the Seychelles summed it up honestly: “the Seychelles is pretty well one of the worst places in the Indian Ocean for actually swimming in the sea”. He’s right.

This private island is full of giant millipedes warms which enter your villa, your underwear, clothes and food! Outrageously expensive : £3000+ a night for a villa and you get to experience this phobia!

I and my husband booked our stay for 6 nights via Knightsbridge Circle Luxury concierge company based in London.

After 3 nights, upon waking up with these millipedes next to my bed and clothes, I had enough and demanded to leave the island immediately.
We moved to the newly opened Six Senses resort which was free from any of these creatures and had great service.
So we basically had to pay again for our holiday.
I have been several times to Seychelles to different islands. These millipedes are native to Fregate Island only.

On top of that, Fregate private island whose management charges outrageous amounts to their guests, does not have any activities! They do not even have a proper boat to begin with. We booked a private day trip to the other islands and they wanted to put us in a transport ferry boat, can you imagine?

To give some credit, their beaches are beautiful but warning: you can’t swim in any because of strong currents and waves and also to get to them there are like 200 steep stairs down. My husband slipped and fell on his back. Very dangerous.

Last but not least, there were like 300 types of birds nesting and pooping everywhere.

To sum up: this island is not adequate for tourism. They need to make a lot of changes and lower their unreasonable prices.
