Relatively easy park and grab, located just off the end of the bike trail. Does not require crossing the street or wading in the river.
Congratulations Dud&Plato for original FTF!
If you're traveling the Poudre Trail, you've reached the northmost end of it. Here, you'll find the town of Bellvue (you can see the whole town from where you're standing), and Watson Lake + fish hatchery, as well as a handful of caches.
The area is fairly heavy traffic, especially during evening and midday, so you might have to exercise stealth. Be sure to check out the other caches in the area!
Climbing down the rocks is not necessary. Watch out for bugs and snakes. Cache container has been changed; it is now a small plastic can. BYOP.
