Depending on where you stay, you can walk to most parts around town. You can catch a Xe Om (motorbike taxi) from most corners, so if you're going somewhere farther out of town, you have a fast way to get there. Taxis are also abundant and reasonable in price.
You can also rent a motorbike by the day.
TO/FROM THE AIRPORT
The Vietnam Airlines shuttle bus between Lien Khuong Airport and Dalat (35,000d, 30 minutes) is timed around flights, leaving from the door of the terminal and, in Dalat, from in front of 40 Street of Ho Tung Mau, two hours before each departure.
Private taxis can be hired to make the trip for around US$12, while a motorbike taxi should cost about USS10.
Pedal power is a great way of seeing Dalat, but the hilly terrain and long distances between the sights make it hard work. Several hotels rent out bicycles and some provide them free to guests. It's also worth looking into cycling tours.
Dalat is too hilly tor cycles, but a motorbike is a good way of getting around. For short trips around town (15.000d), xe om drivers can be flagged down around the Central Market area. Sell-drive motorbikes are US$6 to US$8 per day.
