Your Adventure Wedding Proposal Ideas

Hot Air Balloon
Organise a sunset/sunrise hot air balloon ride and propose while her head's in the clouds.

Field Writing
Mow the question "Will you Marry Me" into a field and then organise a romantic flight over the field and then once the question has been asked head off for a romantic meal somewhere special.

Sky Diving
Take your partner on a sky diving adventure. It's an untaimed and intense emotional exprience. After you pull your shoot, you'll both land traped under you parachute. Ask her to help you out of your chute and when she lifts it, be on one knee holding a ring, asking for her hand in marriage.

Bungee Jumping
Take her bungee jumping. When your partner gets to the the top reveal the letters "Will you marry me? Jump if you want to!" at the bottom.
