I'd like to give backpacking a try. Can anybody recommend a good beginner trail somewhere in the Hudson Valley or Catskills region?

Criteria:

- 25 miles or less, so it can be done in a long weekend.
- easy trail to follow
- camping on or near trail
- swimming hole along the way would be helpful
- a loop so that it finishes where we started would be ideal

My problem isn't so much that I can't find any places that fit the bill but I seem to have too many options. If anyone can help me seperate the wheat from the chaff, I would appreciate it.

Thanks.
