Edinburgh Geocachers say hi! in United Kingdom and Ireland Posted October 24, 2003 Depending on the clue, some caches are possible to find without a GPS. I did about 20 of them before I bought one. I can recommend 'Billy Goat's Gruff' and 'Path to Arthur's Seat' as being Ok to do without a GPS. Also in the Pentlands, 'A hike in the Pentlands' and 'It hot and windy here' are good walks and provide good enough clues. Happy geocaching.
