Safaris can be tailored to different fitness levels. Typical drives last 3-5 hours daily riding in a 4×4 viewing animals with stops. As long as you can sit comfortably through bumpy stretches, you’ll be fine.
Many lodges have pools or massage to rest muscles. Some walking safaris are more tiring, hiking miles across bush finding animals on foot. That requires decent fitness to handle the walking time.
But walking safaris also offer shorter routes or breaks as needed. Discuss your fitness with guides to customize suitable activities. With some strength training beforehand, most moderately active people can fully enjoy a safari.
Seeing incredible wildlife up close makes minor discomforts forgettable. Don’t let fitness worries stop you – with an adventurous attitude, you can find the right safari!
