There isn't a better trek than the Mardi Himal trail if you've never done high-altitude trekking before. No previous trekking experience is necessary because the trails are well-paved for your convenience. However, the path can occasionally be difficult, so it's best to be physically and emotionally healthy before starting the hike. You can engage in some straightforward cardio exercises, such as running, jogging, swimming, etc., to prepare for the trek.
