This cache is hidden in a beautiful location, where you can enjoy fantastic views of the harbour. After you have found the cache, you might even like to continue walking west along the public footpath all the way to Poole Quay. The footpath is next to the water all the way round, so you will have a really scenic walk and lots of fresh air!
Regarding my cache, you will discover that it has a Girlguiding theme. You know already that it is called "Trefoil". And you know that it is across the water from Brownsea Island, where Brownies and Guides love to camp. I hope you like what you find inside, but please leave it there for the next seeker to find!
On a practical note, I can tell you that you will be able to reach down to this cache from the public footpath. The cache is hidden in a round, see-through, waterproof tub. Inside the tub, there is a pencil and paper for you to leave a message. As this is a Girlguiding themed cache, it would be really good if you can leave a comment about your favourite Guiding memory if possible!
Good luck and enjoy!
