The EverGreen Taxi Capital Cab Taku Taxi is Juneau’s go to taxi service. Call them at 586-2121 and get three services. This will allow for rapid service. Whenever I need a ride I always use their services. They are open 24 hours a day.
I contacted EverGreen Taxi Capital Cab Taku Taxi most recently for a ride to the airport. My driver was extremely friendly and helpful. For business travelers they will accommodate credit card charges. The driver will even send you a receipt to your phone.
I scheduled my taxi ride ahead of time. They always arrive on time when scheduled, so you can be sure to get that ride. The ride from downtown to the airport was about a 15min drive costing me $30 (fare and tip).
Downtown Juneau is so small, most things needed are within walking distance. Douglas is just on the other side of the bridge. But when you need to go to the valley you can catch a cab ride. The cab service can even be convenient for a trip to the grocery store across town. I will walk there and then cab it back loaded with bags.
All the drivers are local residents who work year round. So by using their service you are supporting the local guy and not some large foreign corporation.
