Travel: What's the best way to...

Show you're serious about sustainable transport? Sign up for a summer work camp organised by Sustrans, the cycling charity (0117-929 0888) to establish the National Cycle Network. It starts around Loch Venacher in Scotland, 31 May to 14 June, moving south via Scarborough, Lincoln, Leicester, Thame, Sirhowy Valley and Chippenham, finishing at Heligan Gardens in Cornwall, 13 to 27 September. Join for as long as you wish.

Take a botanical tour of Brazil? Join the Friends of Kew (0181-332 5922) for their annual trip to study the flora and fauna. Led by Dr Peter Gasson of the Royal Botanic Gardens, it departs on 7 August for two weeks - including a week-long cruise on the Amazon. The price is pounds 2,538.

Get to Wembley? Except on days like last and next Saturday, you can visit the changing rooms, jog through the players' tunnel and sample the view from the Royal Box on a tour of the stadium (0181-902 8833). Tours take place most days, departing 10am to 4pm (3pm in winter). Admission prices are considerably lower than for the Cup Final: pounds 6.45 for adults, pounds 4.50 for under-15s and senior citizens.

Kill time at Singapore airport? Take the free tour. The airport authority offers a two-hour coach trip around the island, free to any passenger with enough transit time.
