In 2011, REI Adventures, the travel arm of outdoor gear retailer REI, is celebrating its 25th year of offering great outdoor and active journeys to adventure travelers. To commemorate the occasion, they're passing on a substantial discount to members of the REI Co-Op, giving them 25% off some of their most classic trips.

In all, there are seven trips that the discount is being applied to. Those trips include a classic safari in Tanzania, a trek to Everest Base Camp, cycling in the Loire Valley of France, trekking the Tour Du Mont Blanc, hiking the Inca Trail in Peru, backpacking in Fitz Roy and Paine in Patagonia, and exploring the Alaskan wilderness on foot and kayak. Each of these trips is considered to be one of REI Adventures' signature vacations, offering some of the most amazing and memorable experiences for any traveler.

As mentioned, to take advantage of the 25% discount, you must be an REI member. Becoming a member is simple however, and it offers more benefits than just the discount on these trips. There is a one time fee of $20 for the membership, but it entitles you to take part in special events at REI stores, increased discounts on gear items, and a yearly dividend that is based on the items you purchased. That dividend can then be spent on new gear in the store as well. If you're an outdoor enthusiast at all, then the membership usually more than pays for itself in the first year alone.

Members always receive a discount on REI Adventures trips, but the additional 25% savings is on top of that already discounted price. For instance, the African Safari normally costs non-members $4075. Members get the same trip for $3699, but if you take advantage of the added discount, you can visit the Serengeti for just $2775. Not a bad deal at all.

Dates for the discounted trips are limited, so you'll want to take advantage of them as soon as possible. To get more details on these adventures and the dates when they are available, click here.
