My husband and I will be in Hawaii for 2 weeks in May celebrating our 5th wedding anniversary. We will be spending 8 days on Kauai and 6 days on Maui. We are looking for activities off the beaten path, and usually try to avoid crowds and tourists. We are active and enjoy hiking, exploring (both on foot and in Jeep), and relaxing on the beach. A few ideas we have are hiking part of the Kalalau Trail, possibly kayaking along the Na Pali Coast, and hiking the Secret Tunnels trail. We aren't sure about some of the catamaran or Zodiac rides along Na Pali, but my husband would love an 'adventurous' sailing expedition that isn't crowded - does this exist?!? Any activity suggestions would be helpful!
