1. What was the most memorable or exciting part of your holiday?

Trekking with the most amazing mountain backdrop for several days, in Torres del Paine, culminating in the climb up to Las Torres themselves; there just aren't the words to do this place justice.

2. What tips would you give other travellers booking this holiday?

Do some walking beforehand, if you want to get the most from it. Also, don't forget a camera, or you will be truly sorry!

3. Did you feel that your holiday benefited local people, and minimized impacts on the environment?

Since we stayed, ate and drank locally, this should be a positive thing. Minimized environmental impacts is a bit tricky, after a 12-hour long-haul flight and lots of internal flights and long drives, but our final choice to walk lots instead of simply tour in a minivan should help a little.

4. Any other comments?

This is easily one of the best holidays I've ever been on, and my first small-group holiday, which I enjoyed more than I expected (as a general lone-traveller).

We now includes a small charge in the price of its holidays which goes to Climate Care's carbon offset schemes - this has been implemented since Mr Senior booked his holiday.
