The Eiffel Tower © Discover Adventure

The ‘WOW’ factor: Recognisable as one of the most famous structures in the world, the Eiffel Tower, or, as the French nickname her, ‘The Iron Lady’ (la dame de fer), is almost too easy to dismiss, because it is as familiar to us, as ‘Big Ben’ is. Erected originally as the entrance arch to the World’s Fair of 1889, it is Paris’s tallest landmark and the attraction that generates more visitor revenue than any other in the world. It is for that reason and, of course, its striking structural beauty and iconic status that it warrants recognition in our list of ‘must-sees’. Enjoying a Discover Adventure Trek is one way to make a visit even more memorable.

Did you know?: Interestingly, the Eiffel Tower is France’s second-tallest structure, since the late-2004 opening of the Millau Viaduct, which passes over the Tarn Valley in southern France. There are 300 steps from ground to the first floor and another 300 steps to the second floor. Restaurants exist on both upper levels. The third level is accessible only by elevator, even though it also has many steps to its observation platform. The Tower is made from 18,038 separate pieces of puddle iron, with two-and-a-half million rivets holding it together. The Tower can expand by around 15cm in warm weather. Only one fatality was reported during its two year construction period.

Experience: How do you wish to travel to Paris? You can drive, catch the train, or fly. Between September to mid-June, only the stairs are available, between 9.30am to 6.00pm. The costs to reach the second floor are Euros8.10 for adults and Euros4 for children, with Euros13.10/9 for the third floor. If you wish to book a table in either of the restaurants, it is advisable to plan ahead. (www.tour-eiffel.fr; www.eiffeltowerrestaurant.com)

If you wish to join the Discover Adventure trek, it commences and culminates at the Tower, walking past all of the key Parisian sights, and takes place during Bastille Weekend (departing 12th July 2013), with plenty of opportunities to see the marches. The trek includes two nights’ B&B, return travel by Eurostar, lunches, water and snacks for £300pp, or a fund-raising target of £750pp, if raising money for charity (£99 registration fee applies; www.discoveradventure.com).

Eurostar can cover the rail distance from London to  Paris, in reality, quicker than any other form of transport and the current scheduled time is 2 hours and 15 minutes from £69 return. (www.eurostar.com)

If you wish to fly, bear in mind that you will need a taxi or bus from the airport to Paris city centre and British Airways can provide a one-way ticket from Heathrow for £69 per head. (www.britishairways.com/Paris)
