Biking & Country Walking -- Walking or riding along the Delaware River or along the canals built for coal hauling on either side of the river can be the highlight of a summer. The following two routes are particularly convenient: The first is between Lumberville and the point, 3 miles south, where Route 263 crosses the Delaware into New Jersey. The towpath along the canal on the Pennsylvania side is charming, and Lumberville's historic (and newly renovated) Black Bass Hotel (tel. 215/297-5770; www.blackbasshotel.com) is a great riverside destination for breakfast or lunch, as well as dinner or an overnight stay.
The second route, also just south of Lumberville, follows River Road (Rte. 32) south and west to Cuttalossa Road, which winds past an alpine chalet, creeks, ponds, and grazing sheep clanking their antique Swiss bells. In Frenchtown, New Jersey, the fleet of bikes for hire by the hour or day at Cycle Corner of Frenchtown, 52 Bridge St. (tel. 908/996-7712; www.thecyclecorner.com), includes sport/mountain, tandem, and recumbent models, plus kid-friendly trailers and trail-a-bikes; call for hours and prices.
Canoeing & Tubing -- The award for relaxing family fun goes to Bucks County River Country, 2 Walters Lane, off Route 32, Point Pleasant (tel. 215/297-5000; www.rivercountry.net). You can drift down the Delaware -- which stays above 70°F (21°C) all summer and moves at a leisurely 1 1/2-mph pace -- from Upper Black Eddy and Riegelsville back to headquarters 8 miles north of New Hope. Rates are $17 to $48 per person for activities that include tubing, canoeing, rafting, and kayaking (novices can opt for the new single and double sit-on-top kayaks).
Horsing Around in Bucks County -- With admission a mere five bucks a carload, Tinimcum Park Polo Club (www.tinicumpolo.org) matches are a bargain-priced family outing. Boys will relish the excitement of the arduous physical sport, while girls will be thrilled by the equine ballet. Matches are played at Tinimcum Park, 974 River Rd., Erwinna, from 2 to 4pm on Saturday, mid-May to early October, conditions permitting (call the Polo Hot Line on Sat morning; tel. 908/996-3321). You can park on the sidelines and tailgate; there are also a snack bar and a tent with chairs available to the general public. Crowds here are fun and friendly.
