Do all the caches on the trail system where GC23 is located. Also, there’s a letterbox hybrid, Kaniakapu, that’s pretty cool. Takes you to the ruins of Kamehameha’s summer palace. Even the locals don’t know about it.

Have fun. I’d go back in a heartbeat. I also did the EarthCache that’s a 5T. Nice little paddle up a river away from touristy stuff. I didn’t do a lot of caching because I was traveling with my friend non-caching Betty. There was also a fun one on the southern tip of the island. Start at the beach where From Here to Eternity was filmed, crawl through a tunnel and then hike up the side of a dead volcano partway to find the cache. I’d have to look up specific GC codes for all these.

I should add that we stayed in Kailua and the only time we went near Honolulu was to fly in and out and to go to Pearl Harbor and Diamond Head. So I can’t speak to any of the caches on that side of the island.

Non-caching Betty, who is smaller than I am, almost backed out, because it gets narrower as you go up. Then she saw a fairly large lady with her family ahead of her and figured she could do this. It must be a “thing” to do, not just for geocaching.
