散歩 and 遠足: walks and planned outings
Distinguish walking for leisure from an organized outing and its preparation.
Taking a walk
散歩 (さんぽ) means a walk or stroll. 「川沿いを散歩しました」 means taking a walk along the river.
「犬の散歩に出ました」 means going out to walk the dog. に marks the purpose of going out.
An organized outing
遠足 (えんそく) means an excursion, often a school outing. 「学校の遠足で動物園へ行きました」 describes visiting the zoo on a school outing.
「遠足の準備をしています」 means preparing for the excursion. It does not report arrival at the destination.
The name does not determine transport
「遠足では電車を使います」 says the excursion uses a train. 遠足 alone does not require every segment to be on foot.
「散歩の予定でしたが、雨でやめました」 says a walk was planned but abandoned because of rain. The planned action was not carried out.
Does 遠足 require walking for the entire journey?

No. Check the plan or sentence for the actual transport used.
