Sunny Portugal with Porto From $3,299 pp*

You’re a leisurely traveler. You typically take it easy and discover the energy of a new place by people-watching or soaking in the atmosphere at a local café. You can climb at least one flight of stairs, board a coach, and walk unassisted at a relaxed pace for up to 60 minutes without difficulty. You can easily handle altitudes up to 5,000 feet.

You like a balanced approach to travel. Walking two to three miles over the course of a day is no problem for you. You can partake in a two-hour leisurely walking tour, covering up to two miles (with included breaks). You can handle a variety of terrains, from cobblestone streets to moderate hills with relative ease and without assistance. You can climb two flights of stairs with ease. There may be 1 to 2 days on this tour when walking tours can cover 3 to 4 miles over uneven terrain. You can handle altitudes up to 6,000 feet.

You’re an on-the-go traveler. You don’t want to miss a thing, so walking and standing for longer periods of time (2-3 hours) isn’t a big deal. A moderately paced two-and-a-half-hour walking tour, covering several miles, hills, and uneven surfaces, is no problem for you. Walking four miles over the course of a day is very doable, as is climbing into and out of various modes of transportation (tuk-tuk, cable car, zodiac, etc.). You can climb three flights of stairs easily and handle altitudes between 6,000 and 9,000 feet. Expect some longer days balanced with free time to recharge or set out on your own adventure. This level is not a fit for travelers who require mobility assistance devices.

You’re ready to seize the day, whatever it may bring. You lead an active life at home (walking, biking, and half or full day hikes are things you may enjoy) and 10,000 steps a day is normal for you. You can handle longer walking tours (more than 3 hours covering 3+ miles at a steady clip) and activities that involve traversing uneven terrain, steep slopes, standing for periods of time, and varying altitudes and temperatures. You don’t mind being on the go with some early starts, late-nights, and full days. You can handle altitudes of 9,000 feet or higher with little to no issue. This level is not appropriate for travelers who use wheelchairs, walkers, and other mobility assistance devices.
