<h2>Hiking and Horseback Riding in Costa Rica</h2>

Provider: Gap Adventures

Length: 9 days

Price: $499 + $200 local payment

You could pay a lot more for a Costa Rican adventure, but why should you? The <a href="http://www.gapadventures.com/trips/costa-rica-quest/CRQ/2009/" target="_blank">Costa Rica Quest</a> is one of the best bargains to the adventure country, offering more time, activities, and inclusions than similarly priced trips.  

This trip includes a horseback tour of the majestic Monteverde cloud forest, which is similar to a rainforest, with much of the moisture coming from the constant clouds above. And, there's still plenty of free time for optional activities like soaking in hot springs, whitewater rafting, swimming, or kayaking.

<strong>Trip Planning</strong>

Guaranteed departures for 2009 leave on September 19, 26, and 30; October 7, 10, 17, 24, 28, and 31; November 4, 7, 11, 14, 18, 21, 25, and 28; and December 2, 5, 9, 12, 16, 18, 19, 20, 21, 23, 26, 28, and 30. Eight nights' accommodations in hotels are included, as is a horseback riding trip in Monteverde and a guided trip through the cloud forest. Additional optional activities include a day of rafting, a cave tour, a volcano hike, a visit to local hot springs, admission to butterfly gardens, canopy zip lines excursions, dolphin watching, surfing lessons, and much more. No meals are included, and a $300 food allowance is recommended. Airfare is also additional.
