A beautiful reseve running into the center of Blenheim, the Taylor River caters for all. Great spot for running, check. MTB? Yep, a quick way to get to the Wither Hills MTB park to access Mt Vernon. Dog Friendly I hope - sure it. Take pooch, mine loves seeing all his dodgy, oops I mean doggy friends.
I hope I can find a cache or two. You'll be right, if it was flooded you could probably jump from cache to cache all the way to Raupos.
Chuck the tunes in (I prefer rock, raw and old school), get out in the fresh air, get cached up and enjoy the day!
