Start planning a trip to Lord Howe Island. We are in mid 50s and early 60s. Will do snorkeling, swimming in peaceful sea as we are average or below average ocean swimmer. Track walk is ok. perfect 1-2 hours maximum on near flat easy track. So it could be hard for Mt. climb. Will hire a bike (hopefully on paved road) to go around island. Just wondering how long we should plan to stay at island. Also, what is best season for us to go to the island.
