December – 2 weeks, adventure and chill

Hi! First time posting on reddit. Me and my partner are looking for honeymoon ideas for 2 weeks this December. Budget approx £7000 from the UK

looking for: one week adventure – treks, waterfalls, nature one week chill – all inclusive 7 days

Ideally looking in the Americas Have looked at Costa rica which seems top of the list but open to other options. Have looked at staying the chill week in the Caribbean but not sure what do for the first week of adventure, happy with any other close by countries

Thank you!
