Be safe if you plan on using a raft down there man. I havnt seen the levels in a while, but with all the rain tonight, it will probably be moving pretty good.

There's only 2 entrances that I know of for the refuge. The one that follows the river, and the main one just before that and that gate always stays locked. Your looking at a good hike anywhere on the refuge. Theres a high wall on that pretty much runs the length of the refuge on the east side. There's a few places at the beginning to get up and a few near the end, but you can hang it up trying to get over it in the middle unless you have climbing gear.

Good luck and stay safe.
