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 regular size cliplock with a few swaps, hidden at:
N51 48. TESB, TESB, ROTS
W000 22. TPM, TLJ, AOTC
