We're off to Olhos de Agua, near Albufeira and a friend has recommended doing a boat trip from Carvoeiro, to some caves where you can swim. I had a quick Google and it looks great. oes anyone know if it's suitable for a 7 year old and a 10 year old (good swimmers) and if so, where would be a good place nearby to do just a boat trip, without swimming. And how much it might cost? We don't have huge amounts to spend (driving over from where we live in Spain, so it's a cheap holiday for us) and are also committed to doing Zoomarine, so have to budget for that.
Thanks!
