To get to this cache, you can follow the trail along the creek from parking at Maple Ridge Lodge, but it is also accesible from other trails in Mt. Airy. The cache is a bit uptream from the pond. Some climbing is required, and you may get your feet wet depending on the water level. This does not mean, however, that the cache is in the pond. Please make sure that the cache is secured back where you found it.
A few feet off the trail is a cliff that overlooks the pond and can be used to jump from. It is your responsibility to excercise caution if you choose to jump. Make sure the water is deep enough before hand by swimming in first, and also check that there are no rocks or anything that could hurt you. Where I jumped in the water was just above 6', so land on your back if you don't want to shatter your feet on the bottom ;)
If you're up for it, you can follow the creek further back until it leads you to the highway. The is no cache here, but this is where the creek passes under the highway. The tunnels are very long and lead to a bridge on the other side of the highway (West Fork Road) were you can continue to follow the creek as far as you want. Again, if you choose to do this, you are responsible for your own safety. Be smart and do not go in the tunnels when there has been, or you are anticipating, heavy rain. Flash floods could be deadly if you are caught in one while in the middle of the tunnels.
Have fun and be safe!
