We love our caches - and we've started a bookmark list of our favorite Caches..
However if you're looking for 2 awe inspiring caches - yes you need a 4x4 to get to both -
Botanie Mountain - GC155KN - We put a video of the area here: ca.youtube.com/watch?v=sxLBUkCCO-A
This one involves no hiking - it's a straight up drive, it's up near Lytton
The other is Higher then a Kite <below> - GC1FX0F - it's near bridal falls. On the way up you can stop and get some really cool caches - but at the top - you're at the top of the world - this one you have to walk about 300 meters
And if you happen to need a ride and willing to pay gas - we'll provide the transport - but if you have milestones to mark - they are both very worthy
