Fiji is a dream for active travelers who are into diving, snorkeling, swimming, boating, and other watersports. You can also play golf and tennis, or hike into the jungle-clad mountainous interiors of the islands. Kayaking is popular everywhere, and Fiji has river rafting. Good biking can be had along the many roads skirting colorful lagoons. Here's a brief rundown of my favorite active pursuits.
Some travel companies have tours combing several outdoor activities in one trip. For example, Colorado-based the World Outdoors (tel. 800/488-8483; www.theworldoutdoors.com) includes mountain biking, hiking, river rafting, sea kayaking, snorkeling, and sailing in its "Fiji Multi-Sport" tour. Travelwizard (tel. 800/330-8820; www.travelwizard.com) sells diving and surfing packages to Fiji and French Polynesia. Likewise Fiji Adventures tel. 866/755-3453; www.fijiadventures.com) has diving, surfing, river rafting, and windsurfing expeditions to Fiji.
On the Web, Gordon's Guide (www.gordonsguide.com) compiles adventure tours from around the world. It's a good place to search for Fiji-specific adventure trips in a variety of categories.
