MAPS

maps.google.com
Find your destination then click the little orange man icon to switch to Street View and see your chosen location in 360-degree technicolour, the walking versus driving directions to plan your city break amble, and the hotel finder tool (type "hotels in X" in the search box and select "Businesses" in the search options dropdown. When the hotels are plotted on the map you can click on the pointer icon then through to "more info" for details, reviews, photos and maps), plus link to photos that have been linked to your destination and so much more. There is also www.googleearth.com - satellite imagery allows users to zoom in on streets in photographic quality, and overlay onto a map.

WEATHER

www.metcheck.com
Great for travel within the UK - particularly the 14-day forecast for postcode locations in the UK, which is split into three-hour blocks.

www.weather2travel.com
Check the weather where you're going, or choose your next holiday by temperature. Just enter your month of travel and the site returns a list of destinations where the temperature, humidity and hours of sunlight mean you'll come back with a healthy glow. Alternatively you can pick somewhere wet and windy, if that's what you'd prefer.

FLYING WITH KIDS

www.babygoes2.com
Comprehensive site for parents looking for advice on where to go, what to take, and which travel companies are the most child-friendly.

www.family-travel.co.uk
For destination reports, including attitudes to children, eating out, where to stay and a forum, but it costs £14.95 a year.

www.mumsnet.com
This popular parenting site has no travel section as such but does include holiday reviews, travel forums and great tips for travelling with kids.

DISABLED TRAVELLERS

www.holidayaccessdirect.com
A clean and easy-to-navigate site offering links to special-needs flight services, disabled-friendly accommodation, car rental, insurance, taxis, resort support and mobility equipment suppliers. Also check out www.tourismforall.org.uk for hotel bookings and to order its UK hotel guide.

STAYING IN TOUCH

www.pc2paper.co.uk
Hearing a ping from your inbox versus a rustle through the letterbox - it's no competition: letters beat emails hands down. Or perhaps you want to contact a granny who isn't on the internet. Whatever your reason, this site allows you to send a letter without putting pen to paper - it transfers text and images to a letter and sends it worldwide (30p-86p per letter). It also has a free address book so you don't need to travel with your little black book. Also try www.ppme.co.uk where you can turn a photo into a postcard and send it anywhere for 99p including postage.

RED TAPE AND ESSENTIALS

www.biba.org.uk
Get advice on precautions to take before travelling, get in contact with a registered travel insurance broker, or seek advice if you're having difficulties making a claim.

www.ehic.org.uk
You shouldn't travel in Europe without registering for a European Health Insurance Card, which will entitle you to free or reduced cost medical care if you become ill or have an accident while travelling in Europe.

www.jpmorganclimatecare.com
Busy trying to be a green traveller, but concerned by the amount of air travel to get to those eco-destinations? You can donate money — which is given to projects that reduce emissions — to offset the effects of your trip. Also see www.puretrust.org.uk, which is a registered charity and www.co2balance.com, which has a rail calculator as well as road and air.

HEALTH

www.who.int/en/
Together with www.fco.gov.uk this is a site you should visit before going to a developing country. The country guides are exhaustive, with all the data you need to know, and lots more besides, concerning the incidences of disease and level of health care.

www.travelturtle.com
Travel health advice, by country, by disease and by vaccination. The site has gleaned information from its sister site, Pulse, an online resource for GPs, so its advice has been provided by certified medical practitioners.
