I have placed a few caches to coincide with my International Geocaching Day 2018 event and decided to set some simple puzzles for them.
All footpaths are fairly flat, hard, gravel paths. I had no issues with a pushchair.
The Cache is a small cliplock hidden at:
N51 48.eigughutchtut hutchunundudrugedud anundud nuninunetutyub fufourug
W000 22. fufourug hutchunundudrugeded anundud fuforugtutyub tutwasho
