Primal scream: Hippos luxuriating in a Tanzanian waterhole (Corbis)
PRIMAL: TANZANIA
Start your marriage off with a roar on a wildlife-watching trip to Serengeti National Park, home to several million animalsincluding 1.5 million wildebeests. Visit during the dry season, July through October, when animals congregate around dwindling watering holes, or January through March to witness wildebeests calving by the thousands.
Private luxury camping is the way to goobserve lions, zebras, hippos, giraffes, cheetahs, leopards, gazelles, impalas, and ostriches from a Land Rover; cooks prepare your meals. Africa Adventure Consultants can customize a honeymoon safari (12- to 14-day trips cost $250-$750 per person per day, not including airfare; 866-778-1089, www.adventuresinafrica.com).
SULTRY: FIJI
Boredom is not possible at the Namotu Island Blue Water Sports Resort. But boardom is. In this private island kingdom you spend your days surfing, windsurfing, and kitesurfing the Pacific rollers pounding the five-acre spread of sand on the outer fringes of the Mamanuca Islands.
When you're not catching Namotu Lefts, Wilkes Pass, Swimming Pools, and other notable pipes, you stay in one of a handful of traditional Fijian bures, simple wood-frame huts ($2,510 per person per week; Waterways Travel, 800-928-3757, www.waterwaystravel.com).
VIGOROUS: MAINE
A good paddling is one idea of honeymoon fun. If it's yours, tackle some of the Maine Island Trail (www.mita.org), a 325-mile coastal route from Casco Bay to Machias, by sea kayak. Small, public islands along the trail, some of them part of Acadia National Park, allow you to overnight in wilderness.
The tides and currents are challenging, so if you want to go with an outfitter, try Maine Island Kayak Company (800-796-2373, www.maineislandkayak.com) or Old Quarry Ocean Adventures (207-367-8977, www.oldquarry.com).
