Amazing riding, bike hotels (google) are great as you can get good accommodation and food, uplift etc. Eat on the seafront and there are a few decent value hotel options like medusa.
I’ve camped before but fancy a fly and hotel option next time. Trail riding is brilliant, id echo the comments of guiding especially for a long weekend, but with some more time and if your happy pedalling exploring is great. We did the classics but went off the old xc maps too and a bit of nose following and although probably 75% of what we found was overgrown and hard to follow the few trails that were good were brilliant, and they weren’t on the regular stuff.
Although my number one reccomendation, don’t drive down for a long weekend. It’s a bloody long way… if your driving do a week at least.
Also don’t go in high summer, cracking destination for early spring/late autumn when it’s a bit more grisly here. I drove over from the alps in July a couple of years ago and it’s just too hot and too busy. The first 4 days were spent ill with heatstroke and the beach was rammed!
