The dry season from September to May offers the clearest skies and most reliable trekking conditions, especially if you're planning trips to the Simien Mountains or multi-day circuits. The rains (June-August) can make highland trails slippery and cloud out views, though the landscape turns vivid green. December to February is peak season and warmest.

Day trips around the lake and city tours can often be arranged with a day or two's notice, but if you're planning a 4-5 day northern Ethiopia circuit touching Gondar and Lalibela, booking at least a week or two ahead gives you better guide availability and smoother logistics. Check before you go if you need permits for the Simien Mountains.

Yes. Most visitors hire guides for both city tours and anything beyond Bahir Dar - the history and cultural context at monasteries, rock churches, and ruins is dense, and a good guide transforms the experience. Private guides are commonly booked for flexibility, especially on romantic or custom itineraries.

The city center is walkable, but for Lake Tana boat trips, the Blue Nile Falls, and outlying sites, you'll want to arrange transport through your tour operator or hotel. Most multi-day tours include vehicle and driver as part of the package.

Day trips usually cover guide, transport, and entry fees; longer circuits typically add meals and accommodation. Check before you go on specifics - inclusions vary between operators. Romantic tours and private experiences often give you more control over pace and stops.

City tours and gentle Lake Tana boat days work well for mixed abilities. Longer treks to the Simien Mountains or multi-day historical circuits involve altitude, hiking, and rough roads - check the difficulty level before booking and discuss any mobility concerns with your operator.
