We landed at the Jekyll Island Airport which is non-towered and used our cell phone to call the Jekyll Island Club Hotel and they sent a van right over to pick us up.
We rented some bicycles from them, nothing spiffy, just single gear coaster-brake bikes that took a little getting used to, and did a pleasant cycle of the north end of the island.
The trip was partly for a getaway and partly to flex my wings by doing a longer flight in the Diamond DA-20 two seater aircraft. This is a new plane and is a delight to fly. I wish it had more cargo-carrying capacity so I could realistically look at it for a flight up to Canada, but everything’s a trade-off in aviation.
For this reason I expect that any serious trekking will be done in something like the venerable Piper Warrior II workhorse.
By the way, I’ve been to Hilton Head Island (just North of Jekyll Island) a couple of times and found it to be fairly cold and uninviting. It is very obvious that the locals don’t really want you there and they take pains to ensure that you know this. The beaches are largely inaccessible unless you are staying at one of the resorts or unless you know someone locally who can point you in the right direction.
A big exception were the local Hilton Head airport FBO folks at the Carolina Air Center they were great and if I ever do visit Hilton Head again it will be almost solely on the strength of their efforts.
