Siem Reap is small enough for most of its attractions to be within walking distance. Otherwise, visitors can choose between taxis, tuk-tuks, rental cars, and motorcycle taxis to get around the city. Scooter or bicycle rentals are also options, though motorcycle accidents involving tourists are common enough for Siem Reap's authorities to periodically ban rental outlets from servicing foreigners.The roads in and around Siem Reap are generally poor and Cambodia has one of the highest rates of traffic accidents in Southeast Asia. Wearing a helmet on scooters and motorcycles is compulsory (there are spot fines).Tourists mostly use tuk-tuks for travel within the city. Indeed, English-speaking tuk-tuk drivers can double as very effective and informative guides. It's important to negotiate rates with them before setting off.
