Come to Tolmers Activity Centre (EN6 4JS)&#8200;and try your hand at building a raft on the lake! First of all you will have to construct it (we will help)&#8200;and then see if it will float!&#8200;Don’t worry if you need to arrive a bit late, that is fine, however places must be booked in advance via the website. Wear swimming stuff under your clothes and bring a towel. Just in case.....
