Why Intrepid Travel Is the Best Overall Choice

Intrepid is a good fit when you want an active trip without the demands of an expedition.

Its trips typically include:

  • A locally based trip leader
  • Cultural activities and outdoor experiences
  • Free time rather than a fully scheduled day
  • Local transport or locally run experiences where appropriate
  • A maximum group size of 16, with most trips averaging around 10 people
  • Trips designed for different fitness levels and travel styles

The group size creates a social atmosphere without making it difficult to use local restaurants, accommodation and transport. Intrepid also offers family, premium, cycling, hiking, wildlife, sailing and multi-active trips.

Choose Intrepid if you are traveling solo, want a mix of adventure and culture, or need a wide range of destinations without joining a large tour group.

When G Adventures Is a Better Choice

G Adventures is a better fit when you value itinerary flexibility, a broad choice of travel styles or a more informal group atmosphere.

The company describes its trips as locally guided and flexible. Its current Plus itineraries commonly list a maximum of 12 travelers, although the limit depends on the trip. Some itineraries also include community-based experiences and optional activities, giving you more control over how much you do each day.

G Adventures suits:

  • Solo travelers who want structure without a formal atmosphere
  • First-time international travelers
  • People comparing several destinations or budget levels
  • Travelers who want free time and optional activities
  • Trips involving overland travel, wildlife or cultural immersion

G Adventures is the strongest alternative to Intrepid for mainstream international small group adventure travel.

When Exodus Adventure Travels Is the Better Choice

Choose Exodus Adventure Travels when the activity itself is the main reason for taking the trip.

Exodus specializes in hiking, cycling, wildlife, trekking and active cultural trips. Its guided groups usually contain 8 to 16 travelers, with an average of about 10 to 12. Each trip includes an activity level, along with information about walking distances, terrain and physical requirements.

Exodus is a good fit for:

  • Walking holidays
  • Cycling trips
  • Mountain and trekking itineraries
  • Travelers who want clear fitness requirements
  • People who care more about the route and guide than nightlife or group socializing

Choose Exodus when "adventure travel" means hiking, cycling or trekking rather than sightseeing with occasional outdoor activities.

When Backroads Is Worth the Higher Price

Backroads is best for travelers who want premium active travel with strong logistical support.

Backroads focuses on biking, hiking and multi-adventure travel. Its average departure includes about 14 guests, but maximum group sizes vary by trip type. Hiking and walking trips generally accommodate up to 20 guests, while biking and multi-adventure trips can reach 26 guests.

The company uses multiple Trip Leaders and gives guests flexibility over how actively they participate each day.

Backroads makes sense if you want:

  • Higher-end accommodation and trip logistics
  • Cycling or hiking with support vehicles
  • More personal assistance on the route
  • A polished experience for couples, friends or solo travelers
  • An alternative to standard small group tours

Backroads is not the best choice if your priority is the smallest possible group. Its appeal is the quality of the support and the flexibility of the itinerary.

Best Small Group Adventure Travel for Women

AdventureWomen is the clearest choice for women seeking an all-women adventure group.

AdventureWomen has operated women-only trips since 1982. Its departures generally include 8 to 15 guests, with itineraries covering hiking, wildlife, cultural travel, national parks, safaris and expedition-style trips. The company uses five activity levels, from easy-paced cultural trips to more demanding adventures.

AdventureWomen is especially suitable for:

  • Women traveling alone for the first time
  • Women who want a supportive group environment
  • Travelers aged 45 and above who prefer a mature social mix
  • Trips where cultural connection matters as much as physical activity
  • Travelers who want premium accommodation and smaller departures

Is REI Adventures Still the Best Option?

No. The former REI Adventures program is no longer the current option. REI announced that it was exiting its Experiences business, including its previous adventure travel operation.

REI now offers REI Travel, with trips operated by Intrepid Travel. The current program includes small group trips with 4 to 12 other travelers, including US destinations such as Yellowstone, the Grand Tetons and Sedona.

REI Travel is worth considering if you:

  • Are an REI Co-op member
  • Prefer US national park trips
  • Want an Intrepid-operated itinerary
  • Value REI-specific discounts or member benefits

What Should You Compare Before Booking?

The company name matters less than the details of the itinerary. Compare these factors before paying a deposit.

1. Maximum Group Size

A company may advertise "small group travel" while using different group limits for hiking, sailing, family or premium trips. Check the maximum for your exact departure, not just the company-wide figure.

A practical guide:

  • 4 to 8 travelers: Very intimate, but with less social variety
  • 8 to 12 travelers: A good balance of access and group interaction
  • 13 to 16 travelers: Still small, with a livelier social mix
  • 20 or more travelers: Better described as a larger guided group

2. Activity Level

Read the daily itinerary carefully. "Adventure" can mean anything from a short guided walk to several hours of hiking with elevation gain.

Check:

  • Walking distance per day
  • Elevation gain
  • Trail surface and technical difficulty
  • Number of early starts
  • Amount of free time
  • Whether activities are compulsory or optional

Exodus and AdventureWomen provide particularly clear information about activity levels. Intrepid and G Adventures also provide trip-specific physical requirement details.

3. Travel Pace

A 10-day trip visiting five cities is not necessarily relaxing just because the group is small. Look for:

  • Number of one-night stays
  • Long driving days
  • Internal flights
  • Overnight trains or boats
  • Rest days
  • Time spent at major attractions

For a first small group adventure, a slower itinerary is usually a better choice than trying to cover an entire region.

4. What the Price Includes

Compare the full trip cost rather than the advertised starting price. Check whether the itinerary includes:

  • Airport transfers
  • Internal flights
  • Park and attraction fees
  • Breakfasts and other meals
  • Equipment rental
  • Optional excursions
  • Tips
  • A single-room supplement
  • Travel insurance

A low headline price can become less attractive when activities, transfers and meals cost extra.

5. Solo Traveler Arrangements

Most major small group operators accept solo travelers. Before booking, check whether you can:

  • Share a room without paying a single supplement
  • Request a private room
  • Join a departure designed for solo travelers
  • See the approximate age range or traveler profile
  • Extend the trip before or after the group itinerary

AdventureWomen states that many of its guests travel solo, while Exodus says more than a third of its travelers join alone.

The Final Recommendation

Start with Intrepid Travel if you want the safest all-around choice. Compare it with G Adventures when flexibility matters more, Exodus when hiking or cycling is the main purpose, Backroads when you want premium support, and AdventureWomen when you want an all-women departure.

Before booking, compare three specific itineraries based on group size, activity level, pace, inclusions and single supplement. The itinerary that fits your travel habits matters more than choosing the highest-rated brand.
