Welcome to geocaching robby j
Every geocache has a difficulty (D) rating and a terrain (T) rating on a 5-star scale. It is known as the D/T rating.
The following information is provided on the GC Forums but note that D/T ratings vary between regions - it is important to read the cache description and logs for further information if concerned about attempting the cache.
Ratings:
Difficulty - Effort needed to solve and find the cache and logbook at GZ.
Terrain - Physical effort needed to arrive at coordinates.
1 star
Easy to find or solve within a few minutes.
The hike is less than 0.5 mile (0.8 km) and wheelchair accessible (attribute required). Most likely paved and flat.
1.5 stars
Easy to find or solve within 10-15 minutes.
The hike is less than 0.5 mile (0.8 km). Most likely flat but may not be wheelchair accessible.

2.5 stars
A mild challenge, but relatively easy for an experienced geocacher.
