My English is not very well . You can go to Noordwijk. I did it before. You get on the train on Amsterdam to Leiden and than you take the bus to Noordwijk strand. At Huis ter duin ( it's a hotel) and from there it's just 10 minutes walk to the beach. with you stuff maybe 15.
Maybe it's a good plan if you ask here for other kiters in Amsterdam. ANd maybe you can ride with them. Dutch kiters are pretty nice so:)..
thanks for everyone's advice! I'll look forward to seeing you on the water. I'm studying Economics and Business Management. See you on the water and good luck with lessons! Do you know where they will be? Myabe I should check out that spot as well.
