PARK HOURS: 5am to 10pm
BRING A PEN - Would suck to not be able to leave your mark on the log.
When you have a Cliffside Park, you should have a cache on said cliff side. Now, this cache isn't all that high up the cliff, say 15 feet above and about 15 feet back from the creek. The climb up is a bit steep and has many loose rock, so care is in order.
There is another barrier to accessing the cache. Rapid Creek. You see, the cache is on the cliff side of the creek. That in itself wouldn't be such a problem. I have provided an image of the park with rough property lines. As you can see, you can not reach the cache location via a land route without crossing private property. Also, the terrain would not really support a land approach. So, a creek crossing is in order.

As with any water crossing, you need to assess the situation for yourself. While I used a kayak, your method may vary. I can think of wading, kayaking, canoeing and tubing. I guess it really depends on the current flow. It was high the day I made the crossing. The below image was just after the cache placement. The cache hide is in the image.

As previously stated, the only legal access (Unless you know one of the two (2) neighbors) is to cross the creek.
